Overview
One shot player with trigger pin
Discussion
WAV file player in which playback is triggered via an input pin. The input .trigger is a Boolean value which, if set, starts playback. The trigger must be an impulse of length 1 frame, or the initial frame of the WAV will be repeated while .trigger remains set. When .trigger is reset to 0, playback continues from the second frame until it stops at end of the file. If .trigger is set again while in the middle of playback then playback will restart.
...
The module supports only mono playback and first channel of the input wave file is used if it is a multi-channel wave file. Internally the module stores wave data as float values.
