-2147483648 is -Infinity decibels (attenuation),
-2147483647 is -32767.99998474 decibels (attenuation), and
+2147483647 is +32767.99998474 decibels (gain).
A decibel range represented by integer values -2147483648 to +2147483647, where
This scale has a resolution of 1/65536 decibel.
A KSPROPERTY_AUDIO_BASS property request returns STATUS_SUCCESS to indicate that it has completed successfully. Otherwise, the request returns an appropriate error status code.
The filter will succeed a KSPROPERTY_AUDIO_BASS set-property request that specifies a value that is beyond the range of the filter but will clamp the value to the supported range. In a subsequent request to get this property, however, it will output the actual value used.
A tone node can support properties for controlling treble level, mid-frequency level, bass level, and bass boost. For more information, see KSNODETYPE_TONE.
