Common questions
M4A transcription FAQ
Practical details about uploading, processing, and exporting your files.
Can I transcribe an iPhone M4A recording?
Yes. M4A is supported, including common voice memo recordings up to 100 MB.
Do I need to convert M4A to MP3 first?
No. Upload the M4A file directly to Voysum.
What can I download after transcription?
You can download editable text as TXT and timed content as SRT, VTT, or CSV.
Is M4A the same as MP3?
No. Both can store compressed audio, but M4A commonly contains AAC audio. Voysum accepts M4A directly, so changing the extension is not required.
