Sound Processing Kit - SPKit, a C++ object-oriented class library for audio signal processing
Sound Processing Kit is an object-oriented class library for audio signal processing. Sound Processing Kit (abbreviated as SPKit) includes classes for various signal processing tasks, but most importantly, it introduces a way of implementing sound processing algorithms in a simple object-oriented manner. Sound Processing Kit is implemented in C++.
SPKit is designed to be portable. The current version requires a bare-bones C++ 2.0 compatible compiler (templates and exceptions are not needed). ANSI C standard libraries are required. The source code should compile with little or no modification on most UNIX compatible platforms.
There are three versions of the SPKit class library: a “generic” version, a libaudiofile version, and an SGI version. The generic version is the most portable one and does not require extra libraries audio file I/O. On the other hand, the number of supported sound file formats is very limited. The libaudiofile version requires the Audio File Library system for file I/O. Audio File Library is with many Linux distributions and has been ported to other operating systems as well. The home page of Audio File Library is at audio files. The SGI version is written specifically for the SGI/IRIX system.
