Convert FLAC to an SRT subtitle file

FLAC is the lossless compressed audio format favoured by audiophiles, music producers, and archivists. SnailText reads the lossless audio, transcribes the speech with the Whisper model, and writes a phrase-level SRT, all on your machine.

Lossless input means Whisper gets clean audio with no compression artifacts, which tends to produce accurate results. You get a standard .srt file ready to use in any subtitle editor or video player.

How to convert FLAC to SRT

  1. Open the Transcribe files screen in SnailText.
  2. Add your FLAC 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.

FLAC to SRT free, without uploading the file

Online FLAC-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. FLAC works immediately with no extra codec download.

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

FLAC to SRT FAQ

How do I convert a FLAC file to SRT?
Install SnailText, open Transcribe files, add your FLAC, choose SRT as the output, and run it. It generates the SRT locally with the Whisper model, no account and no per-minute charge. FLAC needs no extra codec download.
Does FLAC lossless quality improve subtitle accuracy?
Lossless audio gives Whisper clean input with no compression artifacts, which often produces more accurate transcriptions than a heavily compressed format. Higher sample rates are automatically resampled to 16 kHz before inference.
What is the difference between FLAC to SRT and FLAC to text?
FLAC to SRT produces a timed subtitle file (.srt) with start and end times per phrase. FLAC 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 FLAC 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.
