Settings

Bitrate per channel: Set the AAC audio bitrate per channel. For example, stereo audio with 128 kbps set here will produce a 256 kbps file. If set to "Custom", the recommended range is ≥64 kbps.

Audio Channels: Set the number of audio channels. This setting is most useful when downmixing channels (e.g., from 5.1 to stereo).

Frequency: Set the sample rate of the audio. Music with a full spectrum (20 Hz — 20 kHz) requires values not lower than 44.1 kHz to achieve transparency. More info can be found on the wiki.
