Convert AAC to an SRT subtitle file

AAC is the compressed audio format used by Apple devices, iTunes, and many streaming tools. SnailText reads the AAC audio, transcribes the speech with the Whisper model, and writes a phrase-level SRT, all on your machine.

You get a standard .srt file ready to attach to a video or use in any subtitle editor. AAC works immediately with no extra codec download.

How to convert AAC to SRT

  1. Open the Transcribe files screen in SnailText.
  2. Add your AAC audio file (or a folder of them).
  3. Choose SRT as the output before you run it.
  4. Run it. The .srt file is saved next to your audio.

AAC to SRT free, without uploading the file

Online AAC-to-SRT tools upload your audio to a server. SnailText does it locally: the file stays on your machine, there is no length limit, and the free tier has no watermark. AAC works immediately with no extra codec download.

If you only want the plain transcript of an AAC rather than a subtitle file, the AAC to text page covers that. If you need VTT instead of SRT, the AAC to VTT page covers that.

AAC to SRT FAQ

How do I convert an AAC file to SRT?
Install SnailText, open Transcribe files, add your AAC, choose SRT as the output, and run it. It generates the SRT locally with the Whisper model, no account and no per-minute charge. AAC needs no extra codec download.
What is AAC audio and can SnailText transcribe it?
AAC (Advanced Audio Coding) is the compressed audio format used by Apple devices, iTunes, and many recording tools. SnailText transcribes AAC directly and writes an SRT with phrase-level timing, all locally.
What is the difference between AAC to SRT and AAC to text?
AAC to SRT produces a timed subtitle file (.srt) with start and end times per phrase. AAC to text produces a plain transcript with no timestamps. SnailText does both, you just pick the output before the run.
Does SnailText burn the subtitles into the video when I use AAC to SRT?
No. SnailText writes a separate SRT and VTT file and does not hardcode captions into the video. That keeps the subtitles editable and lets you attach them in any player or editor. If you want them burned in, overlay the file in a video editor afterward.
