SoundWire Audio Communication System
SoundWire lets you stream any music from your Windows or Linux PC to your Android mobile devices. Use it as:
A wireless extension of your PC-based music or home theatre system
A remote speaker or wireless headphones
way to listen to music and movies from your computer anywhere in your house or
out on your deck
SoundWire does audio mirroring. You can use any music player on your PC or laptop like Spotify, YouTube, or iTunes and send the sound directly to your Android device. SoundWire lets you listen to the free version of Spotify on your phone.
SoundWire has low latency (audio delay), which means it can even be used to listen to the soundtrack of a movie or YouTube video while you watch. (Note you must adjust the buffer size in app settings for low latency, see below.) There are other uses too... SoundWire can work as a baby monitor or listening device with any Windows computer such as a netbook that has a built-in microphone. Or hook up turntables to your computer's line input and stream a live DJ set to another part of the house or anywhere else over 3G/4G.
Real-time audio capture and streaming to multiple clients
Excellent sound quality (44.1 / 48 kHz stereo 16-bit, PCM or Opus compression)
Easy to use
Compression option greatly reduces network usage
Stream music from PC to PC running x86 virtualized app
Save everything you hear to a file (MP3 or WAV)
SoundWire Server Setup
Before using SoundWire on your Android device you must install and run the SoundWire Server application on the Windows or Linux PC/laptop/tablet which is your source of music, web audio streaming, or other sounds.
Download SoundWire Server at georgielabs.net. Depending on your PC operating system choose the Windows
7/8/10, Windows XP, or Linux version as appropriate. Raspberry Pi is also
supported. Do not obtain the server from any other web site. Open the ZIP file
and run the installer inside. You must answer yes ("Allow access") to
the Windows Firewall prompt (select both private and public networks). For the
Linux version see the README.txt file for instructions.
Open your favorite PC music application
or web site like YouTube, Spotify, or iTunes
Run the SoundWire Server
program and select the audio source. On Windows 7/8/10 the default settings
should capture what you hear now (“default multimedia device”). On Windows XP
you should select the audio source named “Stereo Mix”, “Wave Out Mix”, “What U
Hear”, or a similar name. On Linux follow the instructions in the README file. You
can send any audio source to your phone, including speaker output, microphone,
line input etc.
4. When music is playing check the SoundWire Server level meter. This shows the volume level of sound being transmitted to your Android device. It shouldn't be too loud (frequent red indication which could mean distortion) or too quiet. Occasional brief red indication is ok. Adjust the level using the volume control of your music player. If an Audio Input slider is shown on the SoundWire server use it as well. On Windows 7/8/10 you can also use the Audio Output slider, but this should normally be set to maximum. On Linux use Pulse Audio Volume Control to show and control volume levels. On Windows XP the Audio Output slider controls your PC speaker volume, not the transmitted audio level.
SoundWire Android App Setup
When the server is running and the level meter shows music
playing, start the SoundWire Android app.
Press the "Connect"
button (coiled wire image) to connect to the server and begin listening. If the
server address box is blank SoundWire will automatically locate the server. When
the wire glows you have a good connection.
If auto locate doesn’t work, or
you have more than one server, enter your server address in the text edit box
before connecting. The server address (IPv4) is shown on the upper left of the
SoundWire Server window, for example: 192.168.1.201. In some situations the
address shown by the server may not be correct, you can find it using ‘ipconfig’
in a command window (look for IPv4 address) or ‘ifconfig’ on Linux. Note that
the SoundWire Server does not choose or control its IP address, that’s
determined by your network configuration.
You can use a long press on the connect button to do auto locate even if the address box is not blank. If you don’t hear any sound check that the level meter on the server shows audio being played and that the status is “Connected”. If the server connection is lost for more than a few seconds you may have to press the connect button again (use the "continuously reconnect" settings option to do this automatically). If you have trouble please see Troubleshooting Tips, below.
Recently Used Server History
Press the “triangle” button beside the server text box to choose from a list of up to four recently used server addresses. This may be useful if you run more than one SoundWire server, or your server address changes frequently and you don’t use auto locate. After selecting the desired address press the connect button. To clear the server history long-press the triangle button. If you run DNS on your network or connect over a WAN you can enter any alphanumeric host name by turning on "Enter alpha server name" in app settings.
Equalizer (Graphic Equalizer, eq)
On devices which support the Android equalizer you can improve the sound of your music using Equalizer and Bass Boost/Surround controls. Press the menu button (three dots) and select “Equalizer”. Turn it on, then adjust as desired. Note: Headphones/Bluetooth must be connected to adjust Bass Boost. Turn the equalizer off to hear the sound without any effects or eq. If the equalizer doesn’t work, see Troubleshooting below.
SoundWire Full Version and Multiple Connections
The full version of SoundWire fully enables Opus audio compression and supports up to 10 connections at once, allowing many different Android devices to receive audio from the server at the same time. It also has a special Pro Mode to set and display buffer latency precisely in milliseconds. SoundWire full version has no ads and no identification voice. For best use of wireless network bandwidth when running several connections you should turn on compression in each Android device and connect the SoundWire Server computer to your network using a cable, not wireless.
Changing SoundWire Settings
Press the menu button (three dots) and select “Settings” to change SoundWire settings. Some setting changes require SoundWire to reconnect, so you may hear a momentary audio gap.
Audio buffer size: This setting controls audio latency. Small buffer sizes give lower latency (shorter audio delay), but can cause choppy sound. Large buffer sizes help eliminate choppy sound, but increase latency. At low buffer sizes SoundWire is fast enough to play audio from movies while watching in real time, although you will need a good WiFi signal and may still notice minor audio glitches. Some Android devices may not handle very small buffers well, if so then increase the buffer size. Don’t use a Bluetooth speaker/headset when you want low latency because Bluetooth often has terrible latency. When you don’t need very low latency select a larger buffer size like 128k. With the SoundWire full version app you can set the buffer size precisely in milliseconds when Pro Mode is enabled. Note that some Android devices place a fairly high limit on the minimum buffer size when not using native audio, so you may want to set native audio to “Auto” in app settings if you haven’t already. Phones and tablets which support Android low-latency audio should also have native audio set to “Auto” for best latency performance, with the correct audio sample rate set at the server. See “Android Native Audio” below for additional tips on latency.
Audio compression: By default SoundWire sends uncompressed audio (PCM) over the network. Turning on audio data compression greatly reduces the required network bandwidth by 90% or more, with virtually no increase in latency. The default bit rate is 128 kbps but may be changed to 256 or 64 kbps (VBR target rate). SoundWire uses the advanced Opus codec which has excellent sound quality at 128 kbps, so you should not normally need to change the bit rate. For voice-only audio a 20 kbps rate is provided, but be careful not to use this setting for music since it results in low-quality monophonic sound. Turn on compression whenever reduced data usage is desirable, e.g. weak WiFi signal or with 3G/4G cell networks. Compression can reduce audio dropouts and make latency more consistent if your WiFi performance is poor. SoundWire may use slightly more battery power when compression is on. Compression requires the full version of SoundWire, in the free version compression will work for a 10 minute trial period.
Connect on start: Connect to the server as soon as the app starts. Uses the last server address entered, or auto-locate if the server address box is blank.
Auto reconnect: Keeps trying to reconnect continuously if the server connection is lost. This may help if you have a poor WiFi connection. Use the “Disconnect” button Ⓧ to stop trying to connect. Note that when this option is on you should always exit SoundWire when you’re finished using it, or disconnect, otherwise your phone will stay awake and run down the battery.
Auto reconnect on settings change: Normally on, turn this off to prevent audio interruptions when changing settings. If turned off you’ll have to disconnect Ⓧ and reconnect manually to make certain setting changes take effect (as indicated by a brief message).
Enter alpha server name: The server address entry field normally uses a numeric on-screen keyboard for convenience when entering IP addresses. If you’d like to enter host names (alphanumeric) then enable this setting. You may also need to enable this setting in rare cases if your numeric keyboard doesn’t include a dot.
Android Native Audio: This
selects an alternate internal audio path (OpenSL ES native audio) which may
perform better or have lower latency on some devices. There are three possible
settings as follows:
Auto – Use native audio with small buffer sizes (32k / 190 ms or less), and standard audio with larger buffer sizes. Recommended for devices that support low-latency audio (Android 4.2+).
Standard audio – Do not use native audio, recommended for devices that don’t support low-latency audio. The standard audio path is more reliable on most Android devices.
Android native audio – Always use native audio, select if the native path performs better on your device even at larger buffer sizes, for example if Auto/Standard have problems.
On modern devices that support low-latency audio the low-latency support only works at a specific audio sample rate (44.1 or 48 kHz) that depends on your device. The required sample rate will be displayed when you click on this option. To minimize latency set your server audio configuration to match the displayed sample rate (see Selecting 48 kHz / 44.1 kHz Audio under Advanced Settings, below).
Mute audio on calls: Normally on, turn this off to continue hearing SoundWire audio during phone calls.
Pro Mode: Turning on Pro Mode lets you set the buffer size precisely in milliseconds, and displays the current buffer latency in real time while connected. This is useful in situations where a specific latency is desired. A new Latency Steering setting appears in the settings menu to control how aggressively SoundWire attempts to achieve the target latency (approximately buffer size divided by 2). Note that the actual audio latency will be higher than the indicated audio buffer latency because many other factors contribute to latency, such as your Android device’s internal audio path and server-side buffering. Use your ears, not the displayed numbers, as the final judge of latency performance. Note: Pro Mode requires the full version of SoundWire.
Server port number: See Advanced Settings, below.
PC to PC Sound Transmission
You can run the SoundWire Android app on any PC under Windows or Linux using virtualization. This lets you send sound from one PC to one or several other PCs. See our simple instructions on how to run Android and SoundWire on a PC using VirtualBox or VMWare.
Low Latency Audio
SoundWire performance and audio latency depend on the software & hardware capabilities of your phone or tablet. Follow these steps for lowest audio latency.
· Make sure you have a good WiFi signal with no interference, and that your wireless network infrastructure (router etc.) is working well. For example, restart your router before a SoundWire listening session.
· Don’t use a Bluetooth speaker/headset when you want low latency because Bluetooth often has terrible latency or latency that builds up or changes arbitrarily. Used a wired speaker/headset.
· Set a small buffer size (8 - 16k, or with pro mode on 40 - 60 ms). If you notice audio glitches then increase the buffer size or turn on compression.
· Turn compression off in SoundWire app settings, unless you need compression on for other reasons like network performance.
· On Android 4.2 or later check whether your Android device supports low latency audio by clicking the Android Native Audio option in app settings. If a message appears which says “Your Android device supports low-latency audio at 44.1/48.0 kHz” ensure native audio is set to "Auto". If the indicated audio sample rate is not the same as being used by your SoundWire server (44.1 or 48.0 kHz) then in Windows 7/8/10 change your output device (speaker) sample rate using the Windows Sound control panel. On Linux or RPi set the SOUNDWIRE_SERVER_SAMPLE_RATE environment variable to 44100 or 48000. See Selecting 48 kHz / 44.1 kHz Audio under Advanced Settings, below, for more information.
· If your phone or tablet does not support low latency audio, try the Android Native Audio option set to Auto or Standard and choose whichever setting appears to give lower latency according to your ear (not numbers shown on screen). If you do not see the Android Native Audio option under Device settings then native audio is not supported on your device.
For more information see the descriptions of the Audio Buffer Size and Android Native Audio settings, above.
Under normal conditions SoundWire allows the latency to vary over a fairly wide range for a given buffer size. This is done to minimize audio artifacts. If you need more consistent latency, for example when listening from more than one Android device, do the following:
· Use SoundWire full version on all Android devices
· Turn on Pro Mode, then set the latency steering option to "Very Tight" on all Android devices (this will make SoundWire try to maintain a specific latency)
· Set your audio buffer size in milliseconds to 500, resulting in a target buffer latency of 250 ms. Use a lower value if you require lower latency.
You may hear more audio artifacts when using SoundWire in this way. When done you should change latency steering back to “Normal”.
Using SoundWire Over 3G/4G
It’s possible to use SoundWire over cell data networks instead of WiFi. We recommend using SoundWire full version with compression turned on. You'll need at least 150 kilobits/sec consistent download speed on your phone and should have an unlimited data plan. You must configure your router to forward UDP port 59010 to your PC. When connecting, enter the correct IP address or host name (don’t use auto locate). To enter a host name turn on the “Enter alpha server name” option in the app (otherwise you can only enter numbers). Unless your PC is connected directly to the internet, don’t use the IP address displayed by the Soundwire server. Use the IP address obtained by your router instead. You can find this address by visiting http://www.tracemyip.org with a browser on your PC. If SoundWire warns that WiFi is not enabled you can ignore this warning when connecting over 3G/4G. Select the largest buffer size (512k) in the Android app settings, and check that compression is on. You might need to set an even larger buffer if you get dropouts, if so turn on Pro Mode and try a buffer size of 4000 or 5000 ms. If you set a large buffer size and see the message “Could not initialize audio playback” then the buffer size is too large and should be reduced, or turn on the Android Native Audio setting to allow large buffers up to 8000 ms.
Using SoundWire Over WAN
To use SoundWire over a Wide Area Network follow the same steps as for 3G/4G above. For example, your phone may be connected to WiFi at work or at a friend’s house and communicate with the SoundWire Server running at your home.
Using SoundWire With Bluetooth Tethering
It's possible to use SoundWire over a Bluetooth tethering network connection. This may be useful if you have a poor WiFi signal, or no WiFi access point. Follow these steps.
· Set up Bluetooth tethering between your PC and Android device (phone) in the normal way.
· To test that it's working, disable the regular network/WiFi on your PC and check that the PC can access the internet through your phone's internet connection (if phone has one).
· Auto-locate won't work, so you'll need to enter the correct IP address in the SoundWire app. The Bluetooth IP address will probably not be displayed by the server, to find the address do this: In Windows open a command window (cmd). Type 'ipconfig' and look for "Bluetooth Network Connection", IPv4 Address. Use this address in the SoundWire app.
· If the address starts with 169.254 then your Bluetooth tethering connection did not obtain an IP address properly, disconnect Bluetooth and try again.
· If sound is choppy your Bluetooth tethering connection may be too slow, turn on compression or increase the audio buffer size.
It’s also possible to use SoundWire over WiFi tethering or USB tethering using a similar procedure.
How to Stream Both Microphone (Headset Mic) and Speaker Audio From Your PC to SoundWire
In SoundWire Server make sure your speaker output is selected (normally “Default multimedia device”). Then in Windows,
Right click on the small speaker
in the bottom right of your PC screen. Select Recording devices tab.
Select your microphone in the
list, click Properties (or double click on the microphone entry).
3. Switch to the “Listen” tab, check “Listen to this device”. Click Ok.
While Listen is checked your microphone will be audible through your speakers so you may want to turn down your speakers. You should hear both your microphone and your speaker output in SoundWire. If you mute your PC speakers this might block microphone audio, so unmute and turn your speaker volume very low.
Recording Audio to a File
On SoundWire Server press the round red button to start saving audio to a file in MP3 or WAV format. When done, press the stop button. Does not require an active connection. Note: This feature is not available on the Linux versions of the server, we suggest using Audacity to record audio on Linux. Due to software patents GeorgieLabs cannot distribute MP3 encoding software with SoundWire. To save in MP3 format you must install the LAME MP3 encoder (lame_enc.dll) on your PC, see this page for instructions (Windows section). If you need to edit or change levels in your saved MP3 music try the excellent mp3directcut.
Other Useful Apps
You may want to use an Android remote control app together with SoundWire to control PC music software from your phone. Some good choices include: Timote (Spotify remote), Remote for iTunes, Android VNC, and Unified Remote.
Can’t connect/locate server: Check the network connections on your phone and PC. Auto locate may not work in some cases, so enter the correct server address. In some cases the server might not display the correct address, e.g. multiple network interfaces, or server is behind a router. Use ‘ipconfig’ in the Windows command prompt to see all network addresses (IPv4). Check your firewall settings on the PC. When you first start SoundWire Server it should ask you to allow a firewall exception ("Windows Firewall has blocked some features of this app"), you should answer yes ("Allow access"). You can uninstall & reinstall the server to get this question again (if it doesn’t appear the exception is in place). You may need to manually open a firewall port -- the default port number is 59010 UDP, and 59011 UDP for auto locate. Depending on your network configuration, you may need to open or forward ports in more than one place (e.g. multiple routers/firewalls). In rare cases you may need to change the port number used by SoundWire. To change the port number see Advanced Settings, below. Ensure that the server level meter shows sound being played. If the server reported an error such as “unable to activate audio device” and the level meter isn’t moving then connections will fail until you successfully select an audio input.
Audio is choppy: First try restarting your wireless router. Try selecting a larger buffer size in the SoundWire app settings. Also try turning on audio compression. If this doesn’t help you probably have a poor WiFi connection. You will need a fairly good WiFi signal (2 to 4 bars out of 4) to avoid choppy sound and dropouts. SoundWire shows a warning if you have 2 bars or less out of 4. Heavy network use by other computers on your home network, or high CPU use by other programs running on your PC or phone can also cause choppy sound. Some network problems like interference can cause choppy audio even with a strong WiFi signal. Try setting your wireless access point to a different channel. If your access point has simultaneous dual band try disabling one band.
Can't enter a server address/name with letters or dots in it: Turn on the "Enter alpha server name" option in app settings.
Volume level is too low: Try turning up the volume in your PC music player software and on your phone. On Windows 7/8/10 ensure the “Audio Output” level on the server is all the way up and unmuted. If the server shows an “Audio Input” slider try turning it up. If volume is still too low on Windows 7 open the volume mixer by right-clicking the small speaker icon 🔊 on the bottom right of your screen and selecting “Open Volume Mixer”. Find the volume control for your music player software or web browser and turn it up to the line (not higher, because that may mess up other levels). On Linux try adjusting levels in Pulse Audio Volume Control.
Volume level is too high (level meter shows red frequently or sound is distorted): Turn down the volume in your music player software. If the server shows an “Audio Input” slider adjust it first.
Latency (audio delay) is long: See the section on Low Latency, above.
Equalizer doesn’t work: The equalizer may not be supported on older Android devices. In this case the Equalizer menu option won’t appear. If the equalizer option appears but doesn’t seem to work at certain times, try setting Android Native Audio to “Standard” in app settings.
Message “Could not initialize audio playback” appears when trying to connect after setting a large buffer size: This can be caused by buffer size limits on certain Android devices when using the “standard” audio path. Reduce your buffer size setting. If you really need a very large buffer then go to the Android Native Audio setting and change it to “Android Native Audio”, this enables buffer sizes up to 8000 ms.
Audio gets choppy or stops when screen turns off: This is a known problem with WiFi on some Android devices when on battery power. You might be able to fix it by changing settings. First check that the "Wake Lock" option in SoundWire settings is selected (but not “Screen On Wake Lock”). Next check your phone’s WiFi sleep policy: Go to System Settings > Wireless networks > Wi-Fi > press "Menu" button > Advanced > Keep Wi-Fi on during sleep > change to "Always". If this doesn’t help, enable the SoundWire “Screen On Wake Lock” option, or plug in your phone.
Audio is smooth but quality is bad or not enough bass (server on laptop or tablet): Your PC may be processing audio in an undesirable way, for example laptops may reduce bass to avoid overloading tiny built-in speakers. To fix it go into the Windows Sound control panel, playback device properties, and turn off all sound effects and enhancements like SRS, e.g. Realtek Audio Manager. Also if compression is enabled in the SoundWire app make sure the bit rate is set to 128 kbps or higher. If you've ever turned on the Android equalizer/bass boost/surround in SoundWire then open the equalizer control panel (menu > Equalizer) and turn it off.
Can’t capture speaker output, Stereo Mix not available (Windows XP only): Some PC sound hardware doesn't support capturing speaker audio from Wave Out Mix / What U Hear / Stereo Mix. You may be able to activate the stereo mix option in settings. Alternatively use a short patch cord with two 1/8" stereo plugs to connect your PC audio output to the input, then select “Line In” or “Microphone” in SoundWire Server. More information and pictures here. Consider upgrading to Windows 7 or later since these versions of Windows do not need Stereo Mix to monitor the audio output.
Can’t turn down PC speakers without losing SoundWire audio: Your PC may not allow you to turn down or mute the speaker output without affecting the sound transmitted by SoundWire. If muting the speaker also cuts out SoundWire audio then you must keep the main speaker volume turned up and unmuted. In this case you can silence laptop PC speakers by plugging something into the headphone jack like a connection cable or spare headphones. On Linux you can silence speakers by selecting profile “off" in the Pulse Audio Volume Control configuration tab.
Can’t capture audio from a Windows 7/8/10 application: Some professional music applications on Windows access the audio hardware in “exclusive” mode, or use third-party audio drivers like ASIO. This prevents SoundWire from capturing their audio. You may be able to use the Stereo Mix input source, if not use the patch cord trick described above. This problem can also be caused by DRM music material.
About SoundWire Audio Communication
Capturing and streaming audio in real time with low latency is not easy. Even minor network communication dropouts can make audio sound choppy. SoundWire communicates with the server using an optimized reliable network protocol, and uses concealment techniques to make dropouts hard to notice if they occur and can’t be corrected in time. Increasing your buffer size setting will make audio smoother but also increases latency. Turning on audio compression can also reduce dropouts by reducing network load.
Audio / Surround:
Your Windows speaker outputs may be configured for 5.1 or 7.1 surround sound, or some other multichannel configuration using the Sound control panel (if supported by your audio hardware). In this case you can choose which pair of channels to send to your Android device using controls which appear in the SoundWire Server window. Depending on the number of surround channels available you can choose between the following options:
· Front L/R – front left and right channels
· Fr C/LFE – front center and LFE (low frequency sounds)
· Side L/R – side left and right channels
· Back L/R – rear left and right channels
Normally you should choose Front L/R, which is the default setting.
Selecting 48 kHz / 44.1 kHz Audio: To switch between 48 kHz and 44.1 kHz sample rate audio you must configure your SoundWire Server computer appropriately. On Windows 7/8/10 set the sample rate for your speaker output to 48000 or 44100 in the Windows Sound control panel (right click on the small speaker icon 🔊 in the bottom right of the screen, select Playback tab, find your speakers in the list, click Properties, Advanced). When done restart SoundWire Server. On Linux and Raspberry Pi define environment variable SOUNDWIRE_SERVER_SAMPLE_RATE giving it the value 48000 or 44100. Make sure to configure the Linux Pulse Audio sample rate to match, otherwise sample rate conversion will be required, reducing audio quality and placing extra load on the CPU (see Linux README.txt). When done restart Pulse Audio and SoundWire Server. Note that using the 48 kHz setting may reduce sound quality for typical audio sources like web sites and MP3 files because sample rate conversion from 44.1 to 48 kHz is required. However some Android devices may need 48 kHz audio to enable low-latency audio support. Unless you know your audio source material is 48 kHz you should use 44.1 kHz audio in SoundWire Server (the server will warn you about this when it starts, one time only). An exception to this rule is if your Android device supports low-latency audio at 48 kHz and you want to minimize latency, then you should configure the server for 48 kHz (see the description of the Android Native Audio setting above for details).
Network Port #: To change the network port number used by SoundWire Server set the environment variable SOUNDWIRE_SERVER_PORT to the desired number and restart SoundWire Server (see instructions for setting environment variables in Windows here). You must then set the same port number in the SoundWire Android app, under advanced settings. You can also enter the port number after the server address separated by a colon or comma, e.g. 192.168.9.149:50000 or 192.168.9.149,50000. Soundwire also uses the next port number (one higher) for auto locate. You can use command line parameters to set the port number when starting SoundWire Server instead of the environment variable, see “Multiple Audio Channels Using Multiple Network Ports” below.
Multiple Audio Channels Using Multiple Network Ports: SoundWire Server normally lets you run only one instance of the program, allowing you to stream one stereo audio channel from that PC. Under Windows and Linux it’s possible to run multiple servers, each set to a different network port number. Then by selecting a different audio source for each server you can stream multiple stereo audio feeds (or different surround channel pairs) to different Android devices. You must start each instance of SoundWire Server using the -p command line option to set its port number, for example
SoundWireServer –p 59010
SoundWireServer –p 59020
SoundWireServer –p 59030
This runs three instances of the server set to use the indicated port numbers. In the Android app set the desired port number under advanced app settings, or enter the port number after the server address separated by a colon or comma. Change the port number to listen to a different audio source. Don’t forget to open the additional ports in your firewall(s). An easy way to specify the -p command line option is to add it in the target string of a desktop shortcut. Create multiple desktop shortcuts for the SoundWire Server program, then edit shortcut properties to make each target string specify a different port number. When using SoundWire Server in this way each server instance shows its port number in the title bar for identification. On Linux use Pulse Audio Volume Control to select different audio sources for each SoundWireServer instance.

Music Level Meters and Visualizers
The SoundWire Android app has a minimal user interface with no audio level meters or visualizers. We expect that you’ll switch away from the app as soon as music starts playing. Instead, SoundWire sends accurate stereo metering data to GeorgieLabs Music VU Visualizer Widgets app (if installed). Music VU can be used to display audio level meters, spectrum graphs and waveform visualizers on your home screen while listening to SoundWire. Music VU visualizers also work with other music players on your Android device.
