AAC Encoding Dialog

On saving an AAC audio file, you can adjust the encoding settings.

Note

The availability of options for AAC encoding depends on your operating system.

You can access the AAC Encoding dialog in most parts of WaveLab Pro 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, select AAC (Advanced Audio Coding) as the type. Click in the Encoding field, and select Edit.

Encoder

Allows you to select an encoder.

  • Microsoft Media Foundation is the default encoder on Windows.

  • Apple Audio Toolbox is the default encoder on macOS.

Bit Rate

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.

On Windows, you can only select Constant Bit Rate, whereas macOS allows you to choose from various bit rate modes.
