Upload your M4A file directly — no conversion needed. Our transcriber decodes the AAC inside an MPEG-4 audio container stream, sends it to Faster Whisper on a GPU, and returns a timestamped transcript along with optional SRT and VTT subtitle exports.

M4A is AAC inside an MPEG-4 audio container. It is most commonly produced by iPhone Voice Memos, iTunes / Apple Music exports, and macOS QuickTime recordings.

M4A is lossy (AAC inside an MPEG-4 audio container), but the loss happens in audio bands that do not carry much speech information. Faster Whisper transcribes M4A at 64-256 kbps AAC within ~1% of WAV accuracy on the same source recording. The real accuracy floor is original recording quality (mic, room, speaker clarity), not the M4A codec.

M4A files are typically 1-2 MB/min at 128 kbps AAC so most uploads land well under our 500 MB ceiling. Free accounts can transcribe up to 5 minutes per upload. Paid plans go up to 2 hours. If you are bumping the ceiling on long files, see the audiobook / longform tool which handles multi-hour transcription.

Yes — Faster Whisper supports 99 languages and auto-detects the spoken language in your M4A file. You can also force a specific source language via the advanced settings if auto-detect picks the wrong one (common with accented English misclassified as the listener mother tongue, or with very short clips).

Yes — the transcript includes segment timestamps and word-level timestamps, exported as SRT or VTT alongside the plain-text version. Pair the SRT with the original M4A (or a converted MP4) and you have a subtitled clip ready to publish.

Yes. Enable speaker diarization in the advanced settings and our pipeline runs pyannote.audio on top of Whisper to label each speaker. For best results on M4A, give us at least 30 seconds of audio so the diarizer has enough samples to cluster voice prints. Two-speaker recordings get the most accurate labeling.

No. Our transcriber handles M4A directly — converting to MP3 first would add a re-encoding step (potentially lossy) and waste your time. The one exception is if your M4A file uses an unusual codec our decoder does not recognize (rare); we will tell you that on upload and you can convert via our free Audio Converter.

Yes, that is the most common upload pattern for M4A. Faster Whisper handles clean recordings, noisy ones, and accented speech — you do not need to clean up the audio first. If accuracy is not what you expect, run the file through our Audio Enhancer (free for one pass) to remove background noise, then retry transcription.

Transcription is free for files under 5 minutes. Paid plans use ~1,000 characters per minute of M4A audio. A 60-minute meeting transcribes for 60,000 characters; a 3-minute voice memo is free. M4A-specific note: if your file is mostly silence (e.g. long pauses in a meeting recording), enable Voice Activity Detection to skip the silence and pay only for the speech sections.

Yes. Uploaded M4A files are processed on our GPU servers and automatically deleted within 2 days. We never store the audio long-term, train models on user data, or share with third parties. The transcript stays in your account for as long as you want it.

Yes. POST your M4A file to /api/v1/transcribe/ as multipart form data with the audio file in the `file` field. The response includes the transcript, segment timestamps, optional word-level timestamps, and a job UUID you can poll for SRT/VTT export URLs. Available on all paid plans.
