KSPROPERTY_AUDIO_SAMPLING_RATE

The KSPROPERTY_AUDIO_SAMPLING_RATE property specifies the rate at which a node samples its input stream in order to produce its output stream.

Usage Summary Table

Get	Set	Target	Property descriptor type	Property value type
Yes	Yes	Pin	KSNODEPROPERTY	ULONG

The property value (operation data) is of type ULONG and specifies sampling rate. This rate is expressed as the number of samples per second (the sampling frequency in Hz).

Return Value

A KSPROPERTY_AUDIO_SAMPLING_RATE property request returns STATUS_SUCCESS to indicate that it has completed successfully. Otherwise, the request returns an appropriate error status code.

Remarks

The miniport driver should return an error on a set-property request if the node does not support the specified sampling rate.

This property is used to control the sampling rate for the following node types:

• ADC node (KSNODETYPE_ADC)

• DAC node (KSNODETYPE_DAC)

• SRC node (KSNODETYPE_SRC)
