// enabled in order to prevent an outside user from overriding compression
|
|
// settings. It doesn't do anything in its implementation, except for
|
|
// delegating the const methods and Enable calls to the real GainControl, so
|
|
// AGC can still be disabled.
|
|
//
|
|
// 2) It is injected into AgcManagerDirect and implements volume callbacks for
|
|
// getting and setting the volume level. It just caches this value to be used
|
|
// in VoiceEngine later.
