Frequently Asked Questions - M4A Transcription

What is the maximum M4A file size?

We support M4A files up to 500 MB. For longer recordings, split the file by session or contact us for enterprise batch options.

How accurate is M4A transcription?

Accuracy depends on the bitrate and recording quality. High-bitrate M4A recordings (128 kbps and above) typically achieve 95–98% accuracy. Low-bitrate voice memos (32–64 kbps) typically achieve 85–93%.

Can it identify different speakers?

Yes. Speaker diarization detects and labels each unique voice (Speaker 1, Speaker 2, etc.). Works reliably for 2–6 distinct speakers.

Can I transcribe iPhone voice memos directly?

Yes. iPhone voice memos are saved in M4A format and can be uploaded directly without any conversion. Share the voice memo from your iPhone to your device, then upload it to ForgeFile.

What output formats are available?

TXT (plain text), DOCX (editable Word document), SRT (subtitle file with timestamps), and VTT (WebVTT subtitle file).

Is my recording kept private?

Yes. All files are uploaded over an encrypted TLS connection, processed in an isolated environment, and permanently deleted after you download the transcript.
