The Synthesis ToolKit in C++ (STK) is a set of open source audio signal processing and algorithmic synthesis classes written in the C++ programming language. STK was designed to facilitate rapid development of music synthesis and audio processing software, with an emphasis on cross-platform functionality, realtime control, ease of use, and educational example code. Optional dependencies: * oss, for OSS audio API support * jack-audio-connection-kit, for JACK audio API support Build Options: STK has 3 audio APIs to choose from, that you can control passing the AUDIOAPI variable value to the slackbuild. AUDIOAPI=alsa (default, choose native ALSA API support) AUDIOAPI=oss (choose native OSS API support, requires oss) AUDIOAPI=jack (choose native JACK server API support, requires jack-audio-connection-kit)
