Q-Audio

Q-Audio is a digital audio interface for Q. The package contains three modules which together provide the basic functionality needed to write digital audio applications. The audio module implements a (nearly) real-time audio interface on top of the PortAudio library. The sndfile module allows you to access sound files in various formats using libsndfile. The wave module provides basic operations for creating and manipulating wave data, including operations to convert sample rates, to calculate Fourier transforms, and to display wave data in a GGI visual.
