RTcmix – digital signal processing and sound synthesis language

RTcmix is a digital signal processing and sound synthesis language. RTcmix was derived from cmix.

In certain respects, RTcmix is similar in function to other extant unit-generator-based software languages such as CSound, SuperCollider and (to a lesser extent) JSyn and Max/MSP.

This is free and open source software.

The project provides the following components:

• A library of low-level C/C++ functions and objects for performing most contemporary digital audio and signal-processing tasks
• A substantial set of pre-coded “instruments” instantiating a variety of DSP and sound-synthesis algorithms (click here for a list)
• A fully-featured command-parsing language to allow easy incorporation of algorithmic control procedures in sound generation
• An option to allow the Perl or Python programming languages to be used as the control/command-parsing environment for RTcmix
• A robust and sample-accurate scheduler for timing and arbitrary event-scheduling
  an ’embedded’ RTcmix object and associated library to enable the entire RTcmix language (scheduler too!) to be compiled and used seamlessly within other C/C++ applications
• A TCP/IP socket interface for external control of RTcmix from other processes or machines
  the physical model and PhISEM routines from Perry Cook and Gary Scavone’s Synthesis ToolKit (STK) as well as affiliated RTcmix instruments using the stk routines
• The ability to read/write most contemporary soundfile formats by via Bill Schottstaedt’s sndlib
• A package of examples showing RTcmix use with MIDI, X11/motif, wxWindows, Lisp, Open Sound Control (OSC), OpenGL, etc.
• A set of command-line utility programs for playing and manipulating soundfiles
• A Max/MSP rtcmix~ object, available for both macOS and Windows XP versions of max/msp.
