The sound circuitry digitizes and records sound as 44.1 kHz 16-bit samples. If a sound sampled at a lower rate on another computer is played as output, the Sound Manager transparently upsamples the sound to 44.1 kHz prior to outputting the audio to the Screamer sound IC.
When recording sound from a microphone, applications that are may be affected by feedback should disable sound playthrough by calling the Sound Manager APIs.
