LEAD MP3 Encoder User Interface
Options for the LEAD MP3 Audio Encoder can be set manually through the encoder property page, which is shown in the figure below:
Changes will be applied only when the filter's state is stopped with the ability to set them permanently by selecting Apply, OK, or to abandon changes by selecting Cancel. Positioning the mouse pointer over a control displays general information about that control.
The following table shows the controls and their descriptions:
| Control | Description |
|---|---|
| Input channels static text | Shows the number of input channels. |
| Output channels static text | Shows the number of output channels. |
| Output Bit Rate - list box | Sets the output bitrate of the compressed audio data. The unit is in kbps. |
| The bitrate is the average number of bits that one second of audio data will take up in your compressed bitstream. | |
| 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 influences 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, and 320. | |
| Output channels - list box | Specifies the number of output channels of compressed data. |
When Unchanged - As Input is selected, the number of the output channels equals the number of input channels. Otherwise, the number of output channels will be forced to be the value selected. |
|
| Output Sample Rate - list box | Specifies the output sample rate, in samples per second (Hz), of the compressed audio data. |
| The valid sample rate values are: Input sample rate, 32000, 44100, and 48000. |
