Opus Audio File Encoding Dialog

On saving an audio file in the Opus file format, you can adjust the encoding settings.

You can open the Opus Audio File Encoding dialog from most places where you can select an output file format.

Example

Open an audio file. Select File > Save As. Click in the Format field, and select Edit. In the Audio File Format dialog, set Opus as the type. Click in the Encoding field, and select Edit.

Audio Signal Type

Allows you to indicate the content type of your audio material (Music, Voice, or Any). For Music or Voice, this can enhance the resulting audio quality, as the encoding process is automatically adapted to the audio signal type.

Maximum Bandwidth

Ensures that the bandwidth of your audio file does not exceed a specific maximum value. As a result, the encoder discards any frequencies above this threshold.

Unconstrained Variable Bit Rate

With this option activated, the bit rate in the file is dynamically adjusted and varies while encoding, without any restrictions, based on the complexity of the material. This can enhance the quality/size ratio of the resulting file, compared to the Constant Bit Rate setting.

Variable Bit Rate

With this option activated, during the encoding process, the bit rate in the file is dynamically adjusted, based on the complexity of the material, and continuously approximated to the specified bit rate value. This can enhance the quality/size ratio of the resulting file, compared to the Constant Bit Rate setting.

Constant Bit Rate

With this option activated, the bit rate in the file remains constant during the encoding process, regardless of the complexity of the audio material.

Note

This can reduce the quality/size ratio of the resulting file, compared to a variable bit rate setting.

Note

The bit rate is related to the quantity of data that is used to encode the audio signal. The higher the value, the better the quality, but the larger the output file.

Quality

Allows you to choose the quality, with the scale ranging from 0 (very low) to 10 (very high).

Note

Lower quality settings result in smaller files. The higher the settings, the better the quality,but the longer it takes for the encoder to process the audio file.
