HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your HPS file
Drag and drop a .hps music file from Melee or Kirby Air Ride, or one made with 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, and the loop point is read from the file.
03
Download the WAV
Download one WAV per HPS file, at the file's sample rate and channel count.
HPS
HPS (HALPST) is the streamed music format of Nintendo GameCube games made by HAL Laboratory, such as Super Smash Bros. Melee and Kirby Air Ride. It stores DSP-ADPCM audio in a chain of blocks, with the loop point marked in that chain. Melee modders make custom HPS music with tools such as VGAudio.
WAV
WAV is a RIFF-based audio format commonly used for uncompressed PCM audio. It is easy to edit and broadly supported in recording, broadcast, and desktop audio workflows.
FILE FORMATS
SOURCE
HPS is the streamed music format HAL Laboratory used in GameCube games, best known from Super Smash Bros. Melee and Kirby Air Ride. It stores Nintendo DSP-ADPCM audio in blocks with loop information, so a track can repeat during a match. Players can't open it without vgmstream.
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 | HPS | WAV |
|---|---|---|
| Developed by | HAL Laboratory | Microsoft and IBM |
| File extension | .hps | .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 | Smash Bros. Melee and HAL music | Editing, mastering, speech tools |
| Plays on phones and browsers | No, needs vgmstream | Yes |
USE CASES
Practical workflows where HPS to WAV conversion is useful.
Listen to Melee stage music anywhere
Play Super Smash Bros. Melee .hps tracks on a phone or computer without Dolphin.
Check custom music for a Melee mod
Modders who encode custom stage music to HPS with VGAudio can decode it back to WAV to check the sound and the loop before loading the mod.
Hear where a track loops
Tracks with an inner loop play the intro, the loop twice and a 10 second fade, so you can hear where the loop point sits.
Edit a track in a DAW
Open the WAV in Audacity, Reaper or FL Studio to trim, remix or rebalance a HAL Laboratory track.
Compare original and replacement tracks
Convert the original and a replacement HPS, then line the WAVs up in an editor to compare length, level and loop.
Archive Kirby Air Ride and Melee music
Keep decoded WAV copies of GameCube music that open on any computer, without game-specific tools.
Use music in a combo video
Import the WAV into Premiere Pro, DaVinci Resolve or CapCut for a combo video, highlight reel or retrospective.
Sample GameCube music for remixes
Producers can sample Melee and Kirby Air Ride music in WAV, which every sampler and DAW accepts.
Play music between tournament sets
Local Melee events can load the WAV into OBS or a playlist as break music on stream.
Encode to another format yourself
Start from the WAV to make an MP3, FLAC or OGG file with your own encoder.

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 HPS 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
Inner loops are rendered once more with a 10 second fade, so the WAV runs longer than one pass.
06
Edit the WAV, then encode a new HPS with a Melee modding tool.
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 HPS into WAV on any device.
