IBasicAudio::put_Balance (Compact 2013)

3/26/2014

This method sets the balance of the audio signal.

Syntax

HRESULT put_Balance(
  long lBalance
);

Parameters

  • lBalance
    [in] Value to which to set the Balance property.

    The allowable input range is -10,000 to 10,000.

    A value of 0 sets a neutral balance: both left and right speakers are given the same amplitude audio signal.

Return Value

Returns an HRESULT value.

E_INVALIDARG is returned for values outside the allowable input range and E_FAIL is returned if the underlying device returns an error.

Remarks

As with the Volume property, units correspond to .01 decibels (multiplied by -1 when lBalance is a positive value). For example, a value of 1000 indicates -10 dB on the right channel and -90 dB on the left channel.
