Frequently Asked Questions
Is FLAC better than WAV for transcription?
Both are lossless formats and give equivalent transcription accuracy. FLAC files are smaller due to lossless compression, making them faster to upload.
Why would I use FLAC instead of MP3 for transcription?
FLAC preserves audio quality that MP3 compression discards. For difficult recordings (quiet voices, background noise), FLAC can give noticeably better results.
Can I transcribe a multi-hour FLAC recording?
Yes. Files up to 200MB are supported and processed in parallel chunks automatically.
