CLAM is a software framework for research and application development
on the audio and music domain. It provides means to perform complex
audio signal analysis, transformations and synthesis. It also provides a
uniform interface to common tasks on audio applications such as accessing
audio devices and audio files, thread safe communication with the user
interface and DSP algorithms recombination and scaling.
