TSignalCoreAudioIn.SamplingFrequencyHW Property
|
DSP Master VCL
|
|
|
Specifies the sampling frequency of the recording hardware.
property SamplingFrequencyHW: Double;
When SamplingFrequency and SamplingFrequencyHW are not equal a rate conversion will be applied. The quality and speed of the rate conversion depends upon the values of Ripple and TransBW properties. For good result set Ripple to 1E-6 (120dB noise suppresion) and transBW to 0.1 (upper 10% of total bandwidth will be attenuated).
