HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your DSP file
Drag and drop a .dsp file ripped from a Nintendo game or made with DSPADPCM or VGAudio, or select it from your device.
02
Convert to WAV
Keep WAV as the output format and start. The DSP-ADPCM audio is decoded to 16-bit PCM.
03
Download the WAV
Download one WAV per DSP file. It opens in Audacity, any DAW and common media players.
DSP
A .dsp file holds Nintendo DSP-ADPCM audio with a standard header, as written by Nintendo's DSPADPCM tool or by VGAudio. It is used for music and sounds in GameCube, Wii, 3DS and Switch games and in fan mods. A file can be mono or interleaved multichannel, often with a loop point.
WAV
WAV is a widely supported audio container often used for uncompressed PCM audio. It is common in recording, editing, production, broadcast, and applications that prefer straightforward, high-fidelity audio.
FILE FORMATS
SOURCE
A .dsp file holds Nintendo DSP-ADPCM audio with a small standard header, as used by GameCube and Wii games and their SDK tools. Most DSP files are mono; stereo music is often split into two files, one per channel. The format is decoded by the consoles' audio DSP, which gave it its name.
TARGET
Microsoft and IBM defined WAV in 1991. It normally stores plain PCM audio with no compression, which is why editors, DAWs, broadcast systems and speech tools accept it without question. The price is size: CD-quality stereo takes about 10 MB per minute, and tagging support is limited.
| Feature | DSP | WAV |
|---|---|---|
| Developed by | Nintendo | Microsoft and IBM |
| File extension | .dsp | .wav |
| Compression | DSP-ADPCM | None (PCM) |
| Size vs uncompressed WAV | About 1/4 | Same size (1:1) |
| Tags and cover art | Loop points, no tags | Basic text tags, no cover art |
| Best for | GameCube and Wii sound | Editing, mastering, speech tools |
| Plays on phones and browsers | No, needs vgmstream | Yes |
USE CASES
Practical workflows where DSP to WAV conversion is useful.
Listen to GameCube and Wii music
Play .dsp tracks ripped from GameCube or Wii discs in any media player, without Dolphin.
Check a custom track for a mod
Modders who encode music with DSPADPCM or VGAudio can decode the .dsp back to WAV to check the sound and the loop before testing the mod.
Hear where a loop restarts
Files with an inner loop play the intro, the loop twice and a 10 second fade, so you can hear how the loop joins.
Rebuild stereo from split L and R files
Games that store stereo as name_L.dsp and name_R.dsp give one mono WAV per file. Combine the two WAVs in an editor to rebuild the stereo track.
Edit game music in a DAW
Open the WAV in Audacity, Reaper or FL Studio to cut, remix or master a Nintendo track.
Archive music from older consoles
Keep decoded WAV copies of GameCube and Wii music that open on any computer, without game-specific tools.
Sample Nintendo sounds
Producers can sample GameCube and Wii sounds in WAV, which every sampler and DAW accepts.
Use game music in a video
Import the WAV into Premiere Pro, DaVinci Resolve or Final Cut Pro for a review or retrospective.
Sort a folder of ripped sounds
Convert many numbered .dsp files in one job and audition the WAVs in a file browser to find the track you need.
Encode to another format yourself
Start from the WAV to make an MP3, FLAC or OGG file with your own encoder for a phone or a website.
SUPPORTED FILES
DSP files from GameCube and Wii games are supported.
Files written by Nintendo's tools and game rips.
The most common layout.
Upload each channel file; each becomes its own WAV.
Loops are rendered the way the game plays them.
Upload many DSP files and download the WAVs as a ZIP.
Only convert audio from games you own or have permission to use.
TROUBLESHOOTING
Game audio works differently from normal music files, which explains most surprises.
01
Looping game music is rendered the way the game plays it: the looped section plays once more, then fades out over 10 seconds. A loop covering the whole track plays once.
02
A file holding less than 97% of the audio its header describes was cut off while extracting or downloading. Upload the complete file.
03
The file is damaged, isn't really DSP audio, or was extracted with the wrong tool. Extract it again from the game files and retry.
04
WAV is uncompressed, about 10 MB per minute for 44.1 kHz stereo and more for higher rates or extra channels.
05
Many games store stereo as separate left and right DSP files. Combine the two WAVs in an editor.
06
Other software also uses .dsp, for example for project files. Only Nintendo DSP audio converts.
vgmstream is the reference decoder for game audio, used through foobar2000 or the command line. dragdropdo runs the same decoder in the browser, so you can turn DSP into WAV on any device.

|---|---|---|
| Nothing to install | ✓Yes. Runs in any modern browser. | ~foobar2000 plus the vgmstream plugin, or vgmstream-cli. |
| Works on phones and tablets | ✓Yes. Desktop, Android, iPhone and iPad. | ~No. Windows and command-line tools. |
| Batch conversion | ✓Yes. Add many files and download one ZIP. | ~Yes, with scripts or foobar2000's converter. |
| Share finished files | ✓Yes. Send a unique link from the result page. | ~You upload and share the files yourself. |
| Pricing | ✓Free with daily limits. $2.99 or $6.99 passes for unlimited use, no monthly plan. | ~Free. |
