Free online GBS to WAV converter

Some audio editors and playback devices accept WAV but cannot play Game Boy Sound files. Converting a GBS file renders its synthesized music as audio that can be edited, shared, or played in standard audio software.

What the GBS format is

GBS (Game Boy Sound) files contain music data and playback instructions for Game Boy game soundtracks, rather than a recorded waveform. They are commonly extracted from game ROMs and played with chiptune players that emulate the Game Boy sound hardware. A file can contain multiple tracks.

What the WAV format is

WAV is a container commonly used for uncompressed PCM audio. It is supported by most audio editors and media players, making it useful for editing or sharing rendered music. WAV files are usually larger than compressed audio files.

How to convert GBS to WAV

1. Upload the GBS file on the converter page. You can add several files for batch conversion; each file must meet the size limit shown on the page.
2. Before converting, choose the sample rate and number of channels.
3. Start the conversion, then download the WAV file when it is ready. The conversion runs on the site’s server using FFmpeg.

Offline with desktop software

On Windows, foobar2000 can convert GBS files to WAV with its Game Emu input component and Converter component. Install foobar2000 and those components, then open the GBS file. If it contains multiple tracks, select the track you want in the playlist. Right-click the track and choose Convert → …; select WAV as the output format and start the conversion.

Quality and track limitations

GBS stores instructions for generating sound, not sampled audio. The converter synthesizes the music during playback, so WAV preserves the rendered result—not an original recording—and changing the sample rate does not add detail absent from the source. Because a GBS file may contain multiple tracks, convert each desired track separately if you need individual WAV files.
