40h
Set digitized sound transfer Time Constant
Output 40h, bTimeConstant
Remarks Set the digitized sound I/O transfer Time Constant.
Time Constant is the sampling rate representation used by the DSP. It is calculated
as:
Time Constant = 65536 - (256 000 000/(channels * sampling rate))
The channels parameter is 1 for mono, 2 for stereo.
Only the high byte of the result is sent to the DSP.
