Transcribing your audio…
What an FLAC file actually is
FLAC compresses audio without discarding anything — decode it and you get the original samples back bit for bit. It is the format research corpora and audio archives standardise on, because it halves storage without any quality argument.
What it means for your transcript
For transcription, FLAC gives you WAV-level input at roughly half the file size. That makes it the best choice when you care about both fidelity and upload limits, which is exactly the situation researchers and archivists are in.
The usual problem with FLAC
Some consumer tools still do not export FLAC, so it mostly appears when someone has deliberately chosen it. Files from archives may carry unusual sample rates.
Getting better results
- → FLAC is the right format for material you intend to keep and re-transcribe as models improve.
- → If a FLAC file exceeds the upload limit, exporting to MP3 costs you very little accuracy.
What you get back
Every job returns both versions. Take whichever fits the job.
