Upload the MKV file and we demux the audio track, then transcode to M4A. There is no video pass and no quality loss beyond what the M4A codec itself imposes; the /extract-audio/ tool runs the same pipeline.
Ìgbà bítárátì àwòrán wo ni fáìlì M4A náà lò?
If M4A is lossless (WAV, FLAC), every sample of the source audio is preserved exactly. If M4A is lossy (MP3, AAC, OGG, Opus), the M4A codec recompresses — at the default 192 kbps this is transparent for nearly all source material.
Does the extracted M4A keep the original sample rate?

Not in this step — extract the full audio as M4A 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 MKV 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 M4A container if M4A supports it.
Àwọn àwọn àgbéwọlé M4A lè jẹ́ stereo, mono, tàbí 5.1?

Channel layout is preserved from MKV by default — a 5.1 MKV produces a 5.1 M4A 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 M4A play on iPhone, Android, or car stereo?
