Default bitrate for lossy AIFF is 192 kbps, which is transparent for music. You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The bitrate dropdown is exposed in the advanced options before you click convert.

Audio demux + encode is fast — typically 5 to 15% of the source duration. A 1-hour MP4 → AIFF finishes in roughly 3 to 9 minutes on the standard pipeline; Premium parallelism cuts this further for batch jobs.

Almost always a wrong-stream selection: MP4 had multiple audio tracks and the demuxer picked an empty or auxiliary stream. Use the advanced "audio stream" picker to select stream 0, 1, 2 explicitly, or target an AIFF container that supports multi-track output (FLAC, OGG).
