IAMAudioInputMixer::put_Loudness method (strmif.h)
put_Loudness method enables or disables the loudness control.
HRESULT put_Loudness( BOOL fLoudness );
Specifies whether loudness is on or off. Use one of the following values.
|TRUE||Sets loudness on.|
|FALSE||Sets loudness off.|
If the method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.
Loudness boosts the bass of low volume signals before they are recorded, to compensate for the fact that the ear does not hear quiet bass sounds as well as other sounds.
