Default M4R bitrate is 192 kbps (transparent for music). You can override to 320 kbps (audiophile) or 96-128 kbps (voice / podcast / smaller file). The choice is exposed in the advanced options.

If the M4R format is lossless (WAV, FLAC), you keep every sample exactly. If M4R is lossy (MP3, AAC, OGG), the M4R codec recompresses — quality depends on the bitrate and source audio. We default to 192 kbps which is transparent for almost all content.

Can I extract audio from multiple MP4 files to M4R in one batch?
Silent gaps usually mean the MP4 file had a multi-track audio layout and we picked the wrong stream. Use the advanced "audio stream" option to explicitly pick stream 0, 1, etc., or re-mux all streams to a multi-track M4R container if M4R supports it.

MP3 plays everywhere. AAC / M4A plays on Apple and most Android. OGG / Opus needs a recent player on iOS. The advanced options expose a "device" preset that picks the M4R codec most likely to play on your target.
