Frequently Asked Questions (FAQ)

It is the audio bitrate—how much data is stored per second of sound. Higher values sound better but make larger files and take longer to convert. Speech and lectures work well at 128kbps; music is usually fine at 192–320kbps. The default is 128kbps.

Channels describe how sound is split. Mono (1 channel) is smaller and suits voice; stereo (left/right) suits music. If you are unsure, leave Original unchanged.

Sample rate is how many times per second the sound is measured (Hz). 44100Hz is the CD/music standard; 48000Hz is common in video and broadcast. If you are unsure, leave Original unchanged.
