FLAC Transcription with AI

FLAC is lossless compressed audio — full quality at smaller file sizes, popular for archival recordings and high-fidelity capture. Jackob.ai transcribes FLAC files directly — upload the recording and get an accurate, timestamped, speaker-labeled transcript in minutes.

It works for archival recordings, oral history projects, and high-fidelity capture, in 98 languages. One upload gives you a document (DOCX, PDF, TXT), subtitles (SRT, VTT), and an AI summary.

Frequently asked questions

How accurate is FLAC transcription?

Accuracy depends mainly on recording quality, background noise, and the number of speakers. Clear speech transcribes very well. Test with your own recording on the free plan — no credit card is required.

Does lossless FLAC transcribe more accurately than MP3?

Marginally at best — speech recognition depends on how the audio was recorded, not how it was stored. Where FLAC genuinely helps is archival work: oral-history and preservation projects keep FLAC masters, and you can transcribe those masters directly instead of making lossy copies first.

Can I get the FLAC transcript as a Word document, PDF, or JSON?

Yes. Every transcription exports as DOCX (opens in Microsoft Word and Google Docs), PDF for polished sharing, plain TXT, and structured JSON with timestamps and speaker labels for developers — plus SRT and VTT subtitles. All formats come from the same upload, so you never re-transcribe.

Can I try it for free?

Yes. The free plan lets you transcribe a real FLAC recording each month with no credit card, so you can judge the accuracy on your own audio before paying.

Are my files kept private?

Yes. Files are processed securely, are never used to train AI models, and can be deleted from your account at any time.
