ILMFAC3Encoder Interface

This is the interface for the LEAD AC3 Encoder.

Interface Properties:

long OutputBitrate

Sets the output bitrate of the compressed audio data. Bitrate denotes the average number of bits that one second of audio data will take up in your compressed bitstream. The unit is in kbps. To calculate the number of bytes per second of audio data, divide the bitrate value by eight. Bitrate represents the strength of compression. Also the bitrate has influence on quality. The higher the bitrate, the higher the quality.The valid bitrate values are: {32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256, 320, 384, 448, 512, 576, 640}. |

BOOL SimulateSurround

Enables or disables surround feature simulation.

Possible values are:

long OutputChannelsFlag

A flag that specifies the number of output channels.

Possible values are:

Interface Methods:

HRESULT ResetToDefaults()


Reset the AC3 encoder option values to the default values.


S_OK if connected; otherwise, S_FALSE.
