Scores created in NoteWorthy Composer need to be rendered as audio before they can be stored as FLAC for playback or lossless archiving. An NWC file contains notation and playback instructions, not recorded sound.
What the NWC format is
NWC is NoteWorthy Composer’s native score format, used for creating and editing sheet music. You typically encounter .nwc files when receiving a score made with NoteWorthy Composer, a Windows application.
What the FLAC format is
FLAC is a losslessly compressed audio format. It is suitable for storing rendered music when you want smaller files than uncompressed WAV without losing audio data.
How to convert NWC to FLAC
Online on 101convert.com
- Upload the NWC file on the converter page; multiple files can be added for batch conversion.
- Convert the file to FLAC.
- Download the resulting FLAC file.
The conversion runs on the server with nwc2xml, then MuseScore. A per-file size limit is shown on the page.
Offline with desktop software
On Windows, open the score in NoteWorthy Composer and use File → Export to export it as a MIDI file. Open that MIDI file in MuseScore, available for Windows, macOS, and Linux, then use File → Export and select FLAC as the audio format. MuseScore renders the MIDI playback to audio.
Quality and limitations
FLAC preserves the rendered audio losslessly; it does not preserve the editable score. The sound depends on MuseScore’s playback instruments and settings, and MIDI export may not retain all notation details or playback nuances from the original NWC score.
