Where do flac files come from?
Flac is losslessly compressed audio: the format of archives, oral history projects and anyone preserving recordings at maximum quality without wav file sizes. That is ideal for transcription: all detail is preserved, and Murmel reads flac directly.
How it works
- Upload your file. Drop your flac file into the Studio; conversion is never needed.
- Murmel transcribes. The text is ready within minutes, with speaker labels if you want them.
- Correct and export. Replay the audio next to the text, adjust where needed and export to Word, text or subtitles.
Dutch model, Dutch servers
Murmel runs on a model trained specifically for Dutch speech that makes fewer errors than open-source alternatives such as Whisper in a public benchmark. Processing happens on servers in the Netherlands, your file is automatically deleted after 7 days and is not used for AI training unless you explicitly opt in.
What does it cost?
Prepaid credits cost €1 per 50 minutes of audio (excl. VAT), available from €5 and valid for 6 months: a one-off file costs cents, no subscription. Transcribing regularly? Try 14 days for €0.01 first, then from €9 per month (excl. VAT), cancel monthly.
Frequently asked questions
Is flac better for transcription than mp3?
Flac contains the full audio quality, which can make the difference with quiet speakers, old recordings or background noise. For most ordinary recordings the difference with a good mp3 is small.
Can I have entire archives transcribed?
Yes. Besides the Studio there is an API for submitting files programmatically. Get in touch for volumes that exceed a subscription.
What does converting a flac file to text cost?
