Samples file format

Format for the Orba2 factory samples is PCM signed 16-bit little-endian 48000hz

Mono and stereo seems to work both.

Using non 48khz samples still work, but playback will still happen in 48khz. As result, sample is played in the different speed and pitch is changed. For example, 44khz samples will play 1.08844 faster and became out of tune. This can be compensated by pitch= setting in SampledSound.

Warning:

Audacity seems to lie about file format it is using, and is silently doing some file conversions. Don't trust it. If you are getting bitcrushed broken sound from orba, it is most probably caused by the wrong file format. (not 16 bit, or not pcm)
