AuI ConverteR: mp3 Parameters [Guide]

Tutorials

AuI ConverteR has default mp3 conversion settings to provide better sound quality.

However, you may be need custom settings of mp3 encoding.

To assign custom bitrate, set desirable parameters in command line of mp3 encoder.

  1. Open Settings > Output formats.
  2. At left upper corner, select Output file format "mp3".
  3. In the field "Output converter command line params" find something like (without quotes):
    - for constant bitrate: "-b:a 320k" ("-ab 320k") or
    - for variable bitrate: "-q:a 9" ("-aq 9").
  4. Replace found parameter to:
    - for constant bitrate: -ab N  (N is desirable bitrate 64k, 128k, 256k, 320k) or
    - for variable bitrate:  -aq M (M is digit from 0 to 9; 9 is maximum sound quality).
