Sound - 37

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 Burgundy sound IC.

The preferred sound sampling rate for output is specified in 

the Monitors and Sound control panel when the sound input 

is not in use. The preferred output sampling rate is 

overridden by the setting of the input sampling rate, 

because the input and output sampling rates are physically 

locked together. The sound output sampling rate is always 

44.1 kHz.

When recording sound from a microphone, applications that 

are concerned about feedback should disable sound 

playthrough by calling the Sound Manager APIs.
