Use OGG when a music player, website, or device accepts audio but cannot open a NoteWorthy Composer score. Converting the score requires rendering its notation as sound, then encoding that audio as OGG.
What NWC is
NWC is the native score format of NoteWorthy Composer, a Windows music-notation program. It stores notation and playback instructions—such as notes, tempo, dynamics, and instrument assignments—not a finished audio recording. NWC files are commonly encountered when sharing or editing scores made in NoteWorthy Composer.
What OGG is
OGG is a multimedia container commonly used for audio encoded with the lossy Vorbis codec. It produces compact audio files and is supported by many desktop players, games, and web applications, though some devices and editing programs require MP3 or WAV instead.
How to convert NWC to OGG
The score must first be rendered with instrument sounds; the resulting audio is then saved or encoded as OGG.
Online on 101convert.com
- Upload the NWC file on this page. Multiple files can be submitted in one batch; the per-file size limit is shown on the page.
- Start the conversion and wait for it to finish. The conversion runs on the site’s server using nwc2xml and then MuseScore.
- Download the resulting OGG file or files.
Offline with desktop software
Open-source route: If you have the NWC-to-MusicXML utility nwc2xml, convert the score to MusicXML, open the resulting file in MuseScore, then use File → Export to save OGG if that format is offered by your MuseScore version. If it is not, export WAV and encode it with FFmpeg:
ffmpeg -i score.wav -c:a libvorbis -q:a 5 score.ogg
MuseScore runs on Windows, macOS, and Linux; FFmpeg is available for those systems. The nwc2xml utility may need to be obtained separately.
Using NoteWorthy Composer: In the Windows application, open the score and choose File → Export MIDI. Render the MIDI with a synthesizer such as FluidSynth, producing a WAV file, then encode that file with the FFmpeg command above. FluidSynth and FFmpeg are available for Windows, macOS, and Linux.
Playback and quality
The OGG contains a synthesized performance, not the original notation. Its sound depends on the synthesizer and instrument sounds used; review tempo, dynamics, and instrument assignments before rendering. Vorbis encoding is lossy, so keep a WAV or other lossless render if you need an uncompressed source for later editing.
