Frequently Asked Questions
Does the bitrate of my m4a file affect transcription quality?
Above ~64 kbps for speech-only m4a, no — modern ASR models are robust to typical m4a compression. Below 32 kbps (heavy telephony compression) accuracy drops. If you have an option to re-export from the original recording, 96-128 kbps is the sweet spot for speech. The transcription engine doesn't decode-then-re-encode; your m4a bytes are decoded once and fed straight to the model.
Can AudioToTextAI label different speakers in a m4a file?
Yes. Enable speaker diarization in the upload options and your m4a transcript will include Speaker A / Speaker B / Speaker C labels at every turn. Diarization is acoustic — it doesn't matter whether your m4a is a podcast, a meeting recording, or a phone call.
How long does it take to convert m4a to text?
Plan on roughly 5 minutes of processing per 60 minutes of audio in your m4a file. Adding diarization and AI summary adds a small overhead but the total stays under 1/10th real time for most files. There's no manual step on your side after upload — we email or webhook you when the transcript is ready.
Is there a file-size limit for m4a uploads?
500 MB via the browser upload. For larger m4a files, submit a URL (any HTTPS source — S3, Google Drive direct link, your CDN). The API v2 also accepts pre-signed S3 URLs to bypass our reverse-proxy entirely.
