Retrieves the balance of the audio stream of the preview output.

Parameter	Description
pCapture	Pointer to an IltmmCapture interface.
pBalance	Pointer to a variable to be updated with the balance value. Possible values range from -10000 to 10000, where -10000 indicates that the right channel is receiving no signal, 10000 indicates that the left channel is receiving no signal, and 0 indicates that both channels are getting the same amount of the audio signal.

Returns

S_OK	The function was successful.

Comments

Units correspond to .01 decibels (multiplied by -1 when pVal is a positive value). For example, a value of 1000 indicates -10 dB on the right channel and -90 dB on the left channel.

This property gets only the balance of the preview output.
