Convert AAC to Text
AAC is the audio inside most recordings from phones, cameras and streaming apps, but you cannot read or search a sound file. Upload the AAC and ScribeToAny transcribes it into clean, timestamped text — with optional speaker labels — that you can edit in the browser and export in eight formats. Works on every plan; no software to install.

What you get: a real transcript
Unedited output from a 64-second interview with two speakers (synthetic voices), transcribed with speaker detection on. Only the first lines are shown.
SPEAKER_00 (0:00) Welcome back to Small Shop Stories. SPEAKER_00 (0:02) Today I'm talking to Maya, who runs a tiny bakery on the SPEAKER_00 (0:05) corner of Mill Street. SPEAKER_01 (0:07) Thanks for having me. SPEAKER_01 (0:08) It's really small, just two ovens and a counter. SPEAKER_00 (0:12) So how does a normal day start for you?
1 00:00:00,000 --> 00:00:01,680 [SPEAKER_00] Welcome back to Small Shop Stories. 2 00:00:02,160 --> 00:00:05,320 [SPEAKER_00] Today I'm talking to Maya, who runs a tiny bakery on the 3 00:00:05,320 --> 00:00:06,320 [SPEAKER_00] corner of Mill Street.
Checked against the script, 4 of 189 words differed — a 2.1% word error rate, counting "80" written for "eighty" as an error — and all 14 speaker turns were labelled correctly. This was clean speech; noisy recordings and people talking over each other score lower. See the full transcript and how it was scored
How it works
- 1
Upload
Drop in an audio or video file, or paste a link. All common formats are accepted.
- 2

Export
Edit segments online, then export TXT, SRT, VTT, TSV, CSV, JSON, PDF or DOCX.
Why ScribeToAny
- Handles Advanced Audio Coding (AAC/ADTS) files commonly generated by digital broadcasting, streaming captures, and voice recorders.
- Low-bitrate AAC from phones and streaming captures transcribes well at normal settings; Restore audio helps with noisy sources.
- Zero conversion friction: upload raw .aac or .m4a audio directly to obtain synchronized transcripts.
Frequently asked questions
What AAC files can I transcribe?
Any standard AAC or .m4a/.aac audio — the format phones and cameras record in. There is nothing to convert first; upload the file as it is and the transcription runs on our side.
Which languages does it handle?
About 98, detected automatically, so you do not have to tell it what it is listening to. Non-English audio can be transcribed straight into English on every plan; translating a finished transcript into 134+ languages is free on every plan too.
What can I export?
TXT for a plain document, SRT or VTT for subtitles, plus TSV, CSV, JSON, PDF and DOCX. SRT and VTT come out timestamped, so they line up with the source if it is the audio from a video.
Does a low-bitrate AAC hurt accuracy?
Rarely at normal settings: AAC at 96 kbps or more keeps speech intact, and every file is converted to 16 kHz mono before transcription anyway. Very low bitrates (below about 48 kbps) or noisy sources can blur words — turn on Restore audio for those and proofread in the editor.
Can I check how long my AAC file is before uploading?
Yes. Drop the file into the estimator on this page: it reads the length in your browser, without uploading anything, and shows the duration, an estimated word count (at about 130 words a minute) and the reading time. That tells you in advance whether the file fits the free plan's 30-minute limit.
