Finale .mus files contain notation rather than recorded sound, so they cannot be played as audio directly. Convert one to FLAC when you need a lossless audio file for playback, sharing, or archiving.
What the MUS format is
In music composition, .mus commonly refers to a Finale score file. Finale uses it to store notation and score information; it is not an audio recording. You may encounter these files when receiving scores made with Finale, particularly older versions.
What the FLAC format is
FLAC stores digital audio using lossless compression: decoding it reproduces the encoded audio without lossy quality reduction. It is suitable for playback and archiving, but it does not preserve editable notation. A FLAC made from a score contains a rendered performance, not the score itself.
How to convert MUS to FLAC
Online on 101convert.com
- Upload the
.musfile on the converter page. Multiple files can be submitted as a batch; the per-file size limit is shown there. - Start the conversion, then download the resulting FLAC file or files.
The page’s conversion runs on its server with denigma, then MuseScore.
Offline with desktop software
Free renderer and encoder: MuseScore runs on Windows, macOS, and Linux and can export FLAC, but use it only if the score is available in a format it can open, such as MusicXML. If you can export the Finale score as MusicXML, open that file in MuseScore and choose File → Export, then select FLAC. MuseScore is not a dependable direct opener for Finale’s proprietary .mus files.
Finale and FFmpeg: Open the .mus file in Finale on Windows or macOS and export a WAV using File → Export → Audio. Then use the free, open-source FFmpeg encoder:
ffmpeg -i "score.wav" -c:a flac "score.flac"
Replace the filenames with the actual WAV input and desired FLAC output names.
Quality and limitations
FLAC preserves the rendered audio losslessly, but it cannot restore performance details that are absent from the score. Playback depends on the synthesizer or sound library used during rendering, and converting a notation file does not produce an original studio recording.
