Use FLAC when someone needs to play a Finale score as audio in a player that cannot open notation files, or when you need a losslessly compressed archive of a rendered performance. A MUSX file stores a score, so conversion requires rendering its notes into audio; it does not recover a recording.
What the MUSX format is
.musx is the native score-document format used by MakeMusic Finale. It stores notation and playback instructions, such as pitches, rhythms, tempo, and dynamics, rather than a finished audio waveform. You encounter it when someone shares a Finale project or when opening a score created in Finale.
What the FLAC format is
FLAC is a lossless audio format: decoding a FLAC file reproduces the encoded audio samples exactly. It is useful for archiving or sharing rendered music when you want smaller files than uncompressed WAV without lossy compression. FLAC contains audio, not editable notation.
How to convert
Online on 101convert.com
- Upload the MUSX file on the converter page. Multiple files can be converted in one batch; the page shows the per-file size limit.
- Start the conversion, then download the resulting FLAC file or files.
The conversion runs on the service’s server with denigma, then MuseScore.
Offline with desktop software
Free rendering with MuseScore after exporting MusicXML: Finale is needed to open the MUSX file and export an interchange score. In Finale, use File → Export → MusicXML. Open the exported MusicXML file in MuseScore, then use File → Export, choose FLAC as the format, and export. MuseScore is free and runs on Windows, macOS, and Linux; this route is not a direct MUSX import.
Finale and FFmpeg: In Finale on Windows or macOS, open the MUSX file and export audio as WAV using File → Export → Audio (the available options can vary by Finale version). Then encode the WAV with FFmpeg:
ffmpeg -i render.wav -c:a flac output.flac
Quality and limitations
The FLAC encoder preserves the rendered audio without loss, but the rendering itself depends on the playback sounds, tempo, dynamics, and articulation used by the software. The result may sound different from a live performance or a recording made with another sound library. Check the exported file’s beginning, ending, and playback before sharing.
