A notation program or playback device that accepts audio but not MusicXML needs the score rendered as a sound file. Converting notation XML to FLAC creates lossless audio, but it renders the notes rather than recovering a recording embedded in the score.
What XML means for music composition
In this context, XML usually means MusicXML, a structured format for exchanging sheet music between notation programs such as MuseScore, Finale, and Sibelius. It stores information such as notes, rhythms, instruments, and dynamics; it is not a general-purpose audio file. MusicXML files commonly use the extensions .xml or .musicxml, while compressed MusicXML files use .mxl.
What FLAC is
FLAC is a lossless compressed audio format. It preserves the encoded audio samples exactly while using less space than uncompressed WAV, making it useful for archiving or sharing rendered playback when the recipient needs an audio file.
How to convert XML to FLAC
Online on 101convert.com
- Upload the MusicXML file to the converter. You can add several files for batch conversion; the page shows the per-file size limit.
- Select FLAC as the output format and start the conversion. The conversion runs on the site’s server with MuseScore.
- Download the converted FLAC file or files.
Offline with desktop software
MuseScore is free and open-source, and runs on Windows, macOS, and Linux. Open the MusicXML file with MuseScore, then choose File → Export, select FLAC as the file type, choose a destination, and export. If the score opens with missing or incorrect notation, check that the file is valid MusicXML and review the score before exporting.
Quality and limitations
The FLAC output is a rendering of the score using MuseScore’s playback sounds, not a lossless copy of a recording. Playback sound depends on the selected instruments and sound library, and details such as tempo and dynamics affect the result. XML files that do not contain MusicXML notation cannot be converted this way.
