Using SoundWire, you can expand the availability of sound to an apartment or office where there is a Wi-Fi network. ### Description of the task The task consists of three parts: 1)**sound source**- webcam with microphone, sound card input or Shortwave or WebSDR program in the browser 2)**server for digitizing and transmitting sound over the network** soundWire (free) for Linux 3)**sound client for playing on a smartphone speaker**- SoundWireFree for Android OS ### Why SoundWire? I didn't want to use other servers and clients, such as Shoutcast or Tizonia, since the SoundWire option seemed simpler. ### About the SoundWire server There are versions of the SoundWire server for various operating systems: \*Windows 7/8/10/11 - Linux 64-bit (3.0 Qt5) - Linux 32-bit (2.1.2 Qt4) - Raspberry Pi 32/64-bit (3.1 & 2.1.2) \*WinXP - Linux (all) The distribution download is available from the home page . Since I have Linux Green x64 and Linux Mint x64 OS, so I downloaded the version [Linux x64 QT5](https://georgielabs.net/SoundWire_Server_linux64.tar.gz)(tar.gz archive). ### SoundWire Server Installation Server (PC): - File **SoundWire\_Server\_linux64.tar.gz** unpacked to ~/Downloads/SoundWireServer folder - Started the SoundWireServer server: To work, you need a library - the libportaudio2 dependency. ``` sudo apt install libportaudio2 ``` To work, you need to open two UDP ports to the outside on the PC firewall: ``` sudo ufw allow 59010/udp sudo ufw allow 59011/udp ``` Starting the server. ``` cd ~/Загрузки/SoundWireServer/ ./SoundWireServer ``` The server begins to “record” sound in the system and broadcast it to the network. More precisely, the server starts transmitting data when connecting to port 59010 of the client. The second port 59011 is used to locate the server. You can set the sound source in the "Volume Control" PulseAudio `pavucontrol`, which is launched by the "Open Pulseaudio Volume Control" button or in another way. In the "Volume Control" we change the sound source, for example, to a webcam, which will be located next to the radio station being received. **Setting up pavucontrol for a webcam:** [ ![webcam](https://ra1ahq.blog/images/7/3/8/b/f/738bffeea587cbdb7f3ad4f713d0a2c3a849d77d-webcam.png "webcam")](https://ra1ahq.blog/images/5/1/6/f/c/516fc8d30ec82f7b64a3bdf7bde8882b528edfae-webcam.png) **Webcam with microphone:** [ ![mic](https://ra1ahq.blog/images/8/6/7/e/0/867e059725b284146712b86c9db5f007851b6eb9-mic.webp "mic")](https://ra1ahq.blog/images/0/2/8/c/7/028c78f1f9ea366d9ba2488f5144c1bc3eeff039-mic.webp) If the goal is to broadcast sound from an application, for example, Shortwave (Internet radio station), we start playback in it. The sound source in this case is **Easy Effects sink**(removal of sound from the program) [ ![shortwave_radio](https://ra1ahq.blog/images/e/d/f/7/0/edf70d1e4e02aa8b72e2cac8f58faf5462ce395e-shortwaveradio.png "shortwave_radio")](https://ra1ahq.blog/images/3/8/2/f/6/382f630526cdc6c528479af467b504640d32ccbe-shortwaveradio.png) **Setting up pavucontrol for Shortwave:** [ ![easyeffects](https://ra1ahq.blog/images/9/3/8/6/b/9386b73dbcc9199a5aa120b714f70c1fb178c8d3-easyeffects.png "easyeffects")](https://ra1ahq.blog/images/d/2/d/4/8/d2d48f43cd2cabc60f11d727e405825f3ad2ea95-easyeffects.png) **Permanent server IP address** It is necessary to fix the IP address - instead of dynamic IP, make it static (on the router). Then, write down the IP address of the computer running the SoundWire server ``` ip addr ``` **Upsampling frequency from 44100 to 48000 Hz** Terminated the SoundWire server and set the sample rate variable and started the server: ``` export SOUNDWIRE_SERVER_SAMPLE_RATE=48000 ./SoundWireServer ``` ### Installing and configuring the Android client The client application can be installed from the store **Google Play**: \*[I recommend "SoundWire - Audio Streaming"](https://play.google.com/store/apps/details) We launch the server on the PC. On the client in the application, you need to specify the server IP address and press "Enter", when connected, the spiral symbol in the window will light up more brightly. [ ![client](https://ra1ahq.blog/images/b/e/2/0/5/be205de9c39cea92cc7ab8b1b95784e35a84fa90-client.png "client")](https://ra1ahq.blog/images/6/b/e/4/f/6be4fa1263ed43a177a48924b81d6d0e7ccdfedd-client.png) ### Problems and solutions 1\) The free version displays the message “Free version” once every 30 minutes. You can buy [full version of SoundWire](http://play.google.com/store/apps/details), but you can do nothing. 2\) No sound - set the sound source in pavucontrol to "*Monitor of Build-In Audio Analog Stereo*" or webcam. 3\) Sometimes the sound is interrupted. - if you view pages in a web browser, the processor performance is not enough. Also, in the Android client settings, check the buffer size - I recommend 64 or 128 kB. [ ![buffer](https://ra1ahq.blog/images/2/4/e/e/a/24eeaf84f30c28bd7b1e325d651f8f29513cc4af-buffer.png "buffer")](https://ra1ahq.blog/images/5/d/c/a/a/5dcaa08fd7a88ebe05ac4478d5294c80ca9a7929-buffer.png) ### Network speed requirements Download speed 250 kbit/s, upload speed 120 kbit/s.
