The Sound Object (SndObj) Library is a C++ object-oriented programming library for music and audio development.
[1] It is composed of 100+ classes for signal processing, audio, MIDI, and file I/O.
The library is available for Linux, Windows, Mac OS X, IRIX, and other Unix-like systems.
The library development is now a cooperative project hosted by SourceForge.
The Library also provides bindings for Python (aka PySndObj),[2][3] Java and Common Lisp (through CFFI).
