Upload the MP4 file and we demux the audio track, then transcode to AMR. There is no video pass and no quality loss beyond what the AMR codec itself imposes; the /extract-audio/ tool runs the same pipeline.

If AMR is lossless (WAV, FLAC), every sample of the source audio is preserved exactly. If AMR is lossy (MP3, AAC, OGG, Opus), the AMR codec recompresses — at the default 192 kbps this is transparent for nearly all source material.

Does the extracted AMR keep the original sample rate?

Not in this step — extract the full audio as AMR 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/.

Kini idi ti fáìlì mì AMR ní àwọn ààyè ìtàjú?

Silent gaps almost always mean the MP4 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 AMR container if AMR supports it.

Àwọn àwọn àgbéwọlé AMR lè jẹ́ stereo, mono, tàbí 5.1?

Channel layout is preserved from MP4 by default — a 5.1 MP4 produces a 5.1 AMR 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 AMR play on iPhone, Android, or car stereo?
