IBasicAudio::get_Balance

The get_Balance method retrieves the balance for the audio signal.

Syntax

HRESULT get_Balance(
  long *plBalance
);

Parameters

plBalance

[out] Pointer to a variable that receives the balance.

Return Values

Returns an HRESULT value. Possible values include the following.

Value Description
E_NOTIMPL The filter graph does not contain an audio renderer filter. (Possibly the source does not contain an audio stream.)
E_POINTER Null pointer argument.
S_OK Success.

Remarks

The balance ranges from -10,000 to 10,000. The value -10,000 means the right channel is attenuated by 100 dB and is effectively silent. The value 10,000 means the left channel is silent. The neutral value is 0, which means that both channels are at full volume. When one channel is attenuated, the other remains at full volume.
