YNAMIC BASS BOOST CONTROL
Bass boost is one of the sound features as defined in the
“USB Device Class Definition for Audio Devices”
The bass boost control request data
bBassBoost
controls
the position of the bass boost switch. The position can be
either on or off. When
bBassBoost
is true the bass boost
is activated. When
bBassBoost
is false the bass boost is
off.
When clipping prevention is active, the bass is reduced to
avoid clipping with high volume settings. Bass boost is
selectable via the configuration map (see Table 6).
If byte 19H is loaded with 00H, bass boost is not reported
to the USB host by the device.
Clipping prevention
If the maximum of the bass plus volume gives clipping, the
Bass is reduced. Clipping prevention is selectable via the
configuration map.
De-emphasis
De-emphasis is one of the properties which is not
supported by the USB. De-emphasis for 44.1 kHz can be
predefined in the configuration map selected at start-up of
the UDA1331H.
