popuset

portaudio opus network streamer

Build instructions

Make sure you have libportaudio, libzmq and libopus installed. For example, on OSX, run:

$ brew install portaudio zmq opus

On Debian-based systems run:

$ sudo apt-get install portaudio19-dev libzmq3-dev libopus-dev

Then, checkout the sources and run make inside the source directory.

Usage

popuset implements a fully connectable audio mesh network. Each instance of popuset can be instructed to open a single device (for input, output, or both) and listens for incoming connections (on port 5040 by default, settable with the --port/-p option). popuset instances are targeted at eachother using the --target/-t option. To send audio from computer A's microphone to computer B's speakers, you would therefore instruct computer B to open its output device (using the --device/-d option). You would then tell computer A to open the microphone audio device (via the --device/-d option) and target it at computer B with the --target/-t option. Note that multiple popuset instances can target the same output instance, and they will all be mixed together in realtime.

You can "log" input/output audio to .wav files using the --log/-l option. This is useful for debugging, or just recording audio that other users are sending your way.

Raspi notes

Since we need a newer version of libzmq than is given us by the distribution packages, we need to download/compile it ourselves. First, download/install all necessary dependencies:

$ sudo apt-get install autoconf automake g++ gcc libtool portaudio19-dev libopus-dev

Next, download/compile/install libzmq. Note that this took 25 minutes on my raspi.

$ git clone https://github.com/zeromq/libzmq.git
$ cd libzmq
$ ./autogen.sh
$ ./configure --without-libsodium --without-pgm
$ make
$ sudo make install

Finally, download/compile this puppy:

$ git clone https://github.com/staticfloat/popuset.git
$ cd popuset
$ make
