Cross platform audio streaming over TCP socket demo.

• Both client and server are fully multithreaded.
• Audio can be streamed compressed using Opus codec (Not available by default.).
• Change main settings of streaming without need to recompile the application.
• Support multiple clients connected to the server.
• Clients can see a real time level meter.
• Clients can record the sound.
• Audio can be buffered to reduce the occurrence of buffer underrun in the client side.
• On the client side is possible to set a volume that are directly applied to audio samples.

This application has two modes of usage:

First mode: Configured to compress audio using Opus codec and them stream it.

Second mode: Configured to transmit raw/uncompressed data directly. (default)

Both methods require Qt 5.x.x and Qt Creator.

If you're not intended to compress the audio and just play with raw/uncompressed audio, ignore these steps and go to the second mode of usage.

To enable Opus in your project you need to compile opus for each platform that you are planning to use it.

If you are using windows download it here: https://www.opus-codec.org/downloads/

And see the instructions to compile it: http://lists.xiph.org/pipermail/opus/2013-January/001901.html

Or the instructions to download and compile on Linux/Mac: https://trac.ffmpeg.org/wiki/CompilationGuide/Quick/libopus

Beyond Opus you will need r8brain-free-src (Sample rate converter designed by Aleksey Vaneev of Voxengo), just get it from this address: https://github.com/avaneev/r8brain-free-src

In common.pri file set the appropriate includes and libraries for Opus on your platform and put r8brain-free-src in a subdirectory of the server, like this: AudioStreaming/Server/r8brain

Enable Opus by uncommenting the first line to CONFIG += WITH_OPUS.

Run qmake and rebuild it and you must be able to use it with Opus codec.

In uncompressed mode no extra effort is needed, just get the sources and compile it.
