In short
Upload the FLAC and get the words as text with a timecode on every line and the speakers named on request. FLAC is lossless, so nothing is thrown away, but the file stays big — a file is up to 30 minutes.
How to transcribe a FLAC recording
- 1
Keep the lossless original
The archive copy stays where it is. Upload a copy of it; the transcript is made from the audio, and nothing is written back into your file.
- 2
Check how long it is
A long session in a lossless file does not fit into 30 minutes. The limit of 30 minutes is on one file, so cut the recording by topic.

What a FLAC file costs in megabytes
none: the file decompresses to an identical copy of the original audio data
typically 50 to 70 percent of the original size
an open format with royalty-free licensing and a free reference implementation
audio and video are both accepted: mp3, wav, m4a, mp4, webm, ogg, flac, aac, wma, mov
The case
Why an archive copy has to be split
FLAC is the archive format: lossless compression that unpacks into a copy identical to the original audio. Wikipedia puts the saving at 50 to 70 percent of the source size, which is a lot next to a lossy codec and not much next to a 30 minutes limit. A long lossless recording still has to be split before the upload.
Tips
Keep the lossless master; upload a copy of it.
Split a long set of tracks file by file.
Read the first minute; the names are what you check.
Export DOCX when the transcript goes to an editor.
Questions this page answers
Does lossless audio give a better transcript?
We publish no accuracy number for any format, so we will not claim one. What we can say is that FLAC unpacks into an identical copy of the original audio.
How much smaller is a FLAC file?
Wikipedia says a FLAC file typically shrinks to 50 to 70 percent of the original and decompresses to an identical copy of the audio data.
Can I transcribe a whole album in one file?
Not in one file. One upload is up to 30 minutes, on every plan; a long set of tracks has to go in as separate files.
Does the cover art in the file matter?
No. FLAC can carry tags and cover art, and the transcript is made from the sound. The pictures and the tags are not part of the result.
