If M4A is lossless (WAV, FLAC), every sample is preserved exactly. If M4A is lossy (MP3, AAC, OGG, Opus), the M4A codec recompresses — at 192 kbps this is transparent for almost all content. Recovering quality that was already gone in the MP4 source is impossible.

Does the extracted M4A keep the original sample rate?

Fáìlì mì MP4 jẹ́ aládàkọ́ nígbà ìṣàfihàn àwòrán?

Yes. Uploaded MP4 files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted M4A are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
