Frequently Asked Questions

General

What is AudioSRT?

AudioSRT is an AI Subtitle Studio — a professional subtitle editor and transcription tool that runs in your browser. Upload audio or video, transcribe with Whisper AI or Deepgram cloud, edit subtitles with professional controls, and export to SRT, VTT, Premiere Pro JSON, or burned MP4.

Is it really free?

Browser-based transcription with Whisper AI is completely free — no account required, no duration limit, no file limit. You can transcribe a 10-hour podcast at zero cost. Pro and Studio plans add faster cloud transcription for users who need it.

Do my files get uploaded to a server?

On the free plan, Whisper AI runs entirely in your browser — your files never leave your device. Pro and Studio plans use Deepgram cloud transcription for speed, but your audio is only used for transcription and is not stored.

For Creators

Can I import subtitles directly into Premiere Pro?

Yes. Export the Premiere Pro JSON file from AudioSRT. In Premiere Pro, open the Text panel → click (...) → Import → Import Static Transcript. Your subtitles load frame-accurately onto your timeline as fully editable text. See the full Premiere Pro guide →

Can I burn subtitles permanently into my video?

Yes. AudioSRT can export an MP4 with subtitles burned directly into the video frames — no additional software required. Style your subtitles first, then export the burned MP4.

Can I upload custom fonts?

Yes. Upload any TTF, OTF, or WOFF font and it applies to your subtitle preview instantly. This works on all plans including free. Use your brand font and see exactly how subtitles will look before exporting.

Performance

Why is browser transcription slower?

Browser transcription runs Whisper AI entirely on your device — it's private and unlimited, but speed depends on your local CPU or GPU. It uses Web Workers so your browser never freezes, even on very long files. Pro and Studio plans use Deepgram cloud, which is roughly 10× faster.

When should I use the desktop app?

Use the desktop app when you need up to 20× faster local transcription on supported hardware, want to work offline, or are processing very large files. It uses native GPU acceleration and has no browser memory limits. It is free forever.

When should I upgrade to Pro?

Upgrade to Pro when you need transcription done in seconds rather than minutes, work in multiple languages, or transcribe high volumes regularly. Pro gives you 25 hours/month of Deepgram Nova-3 cloud transcription — 10× faster than browser Whisper with auto language detection.
