Upload the MOV file and we demux the audio track, then transcode to M4R. There is no video pass and no quality loss beyond what the M4R codec itself imposes; the /extract-audio/ tool runs the same pipeline.
Ìgbà bítárátì àwòrán wo ni fáìlì M4R náà lò?
If M4R is lossless (WAV, FLAC), every sample of the source audio is preserved exactly. If M4R is lossy (MP3, AAC, OGG, Opus), the M4R codec recompresses — at the default 192 kbps this is transparent for nearly all source material.
Does the extracted M4R keep the original sample rate?

Not in this step — extract the full audio as M4R first, then use /audio-trim/ to clip the section. The two-step path is faster than a combined operation and lets you preview the extracted track before trimming.

Yes — same privacy model as every conversion on the site: isolated workers, automatic deletion within minutes, no human review of audio or video content. See /privacy/.

Silent gaps almost always mean the MOV file had a multi-track audio layout (commentary, alternate languages, surround backchannels) 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.

Channel layout is preserved from MOV by default — a 5.1 MOV produces a 5.1 M4R where the codec supports it (AAC, FLAC, OGG, Opus). Force stereo or mono with the channel-downmix option; useful for podcast workflows or low-bandwidth playback.
Does the extracted M4R play on iPhone, Android, or car stereo?
