Convert an MGU song when a player, editor, or archive workflow needs a standard audio file rather than a Band-in-a-Box project. FLAC keeps the rendered sound lossless, but it does not preserve the editable song arrangement.
What the MGU format is
MGU is a Band-in-a-Box song file created by PG Music’s Band-in-a-Box for Windows and macOS. It stores musical information such as chords, style, and melody, rather than a finished audio recording. You may encounter it when receiving an arrangement or song project made in Band-in-a-Box.
What the FLAC format is
FLAC is a lossless audio format: it reduces file size without discarding audio data. It suits playback, sharing, and archiving when a device or audio application supports FLAC and you want to avoid lossy encoding. Unlike MGU, FLAC contains rendered sound, not editable chord or melody data.
How to convert MGU to FLAC
Online on 101convert.com
- Upload the MGU file on the converter page; the per-file size limit is shown there.
- Start the conversion. The conversion runs on the site’s server with MuseScore. You can submit several files as a batch.
- Download the resulting FLAC file or files.
Offline with desktop software
MGU is a song project, so an audio renderer must first play or render it; FFmpeg cannot decode MGU directly. Open the file in PG Music Band-in-a-Box, available for Windows and macOS, and use its audio-render or audio-export function to create a WAV file. Then encode that WAV as FLAC with the free, open-source FFmpeg, available for Windows, macOS, and Linux:
ffmpeg -i rendered.wav -c:a flac output.flac
Replace rendered.wav with the WAV filename Band-in-a-Box exported. The exact export menu wording can vary by Band-in-a-Box version.
Quality and limitations
FLAC preserves the rendered audio losslessly, but the sound depends on the instruments, style, tempo, and other playback settings used during rendering. The conversion does not carry over MGU’s editable arrangement, and encoding the render as FLAC cannot recover information absent from that audio.
