cPortaudioWavplayer

Description

This component can play wavefiles directly to a portaudio output device. Multiple wave files can be specified as inputs and they can be played via smile messages containing the index of the sample to play. Concurrent play requests will be discarded (TODO: mix the output). All wave files must have the same sampling rate.
