Чего ожидать
- If the source contains AAC audio,
ffmpeg -c:a copyrewraps it into.m4awithout touching the audio data - the result is bit-identical to the original. - Older Samsung voice memos use AMR audio, which M4A does not support; re-encoding to AAC changes the codec but voice recordings sound the same or better.
- Renaming
.3gato.m4adoes not work - the container headers differ and players will reject the file.
Часто задаваемые вопросы
Does renaming .3ga to .m4a work?
No - the container structure inside remains 3GPP and players will reject or misread the file. An actual conversion is required.
Will I lose quality converting 3GA to M4A?
Not if the source is AAC - a lossless rewrap copies the audio frames unchanged. AMR sources require re-encoding to AAC, but for speech the result sounds the same or better.
How do I check whether my 3GA contains AAC or AMR?
Run
ffprobe input.3ga - it reports the audio codec and tells you whether a lossless copy is possible.Can I batch-convert multiple 3GA files at once?
Yes - with FFmpeg on macOS/Linux run
for f in *.3ga; do ffmpeg -i "$f" -c:a aac "${f%.3ga}.m4a"; done in a terminal.Программы, которые конвертируют 3GA: Apple iTunes for Windows · Any Audio Converter · SUPER · Apple iTunes for Mac · Xilisoft iPhone Ringtone Maker for Mac
