This is the interface for the LEAD AC3 Encoder.
| Type | Name | Description |
|---|---|---|
| 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: |
| • TRUE: Enables surround feature simulation. | ||
• FALSE: Disables surround feature simulation. This property works only if LENCAC3_FORCE_6CHANNELS flag is selected. |
||
| long | OutputChannelsFlag | A flag that specifies the number of output channels. Possible values are: |
• LENCAC3_UNCHANGED: [0x00] The number of output channels equals the number of input channels. |
||
• LENCAC3_FORCE_MONO: [0x01] The number of output channel is 1. |
||
• LENCAC3_FORCE_STEREO: [0x02] The number of output channels is 2. |
||
• LENCAC3_FORCE_6CHANNELS: [0x06] The number of output channels is 6. |
Reset the AC3 encoder option values to the default values.
S_OK if connected; otherwise, S_FALSE.
