HOW IT WORKS
Three steps, no account, nothing to install.
01
Upload your AT9 file
Drag and drop a .at9 file from a PS4 or PS Vita game, such as a snd0.at9 theme, or select it from your device.
02
Convert to WAV
Keep WAV as the output format and start. The ATRAC9 audio is decoded to 16-bit PCM.
03
Download the WAV
Download one WAV per AT9 file. It opens in Audacity, Reaper, FL Studio, Adobe Audition and other audio editors.
AT9
AT9 files contain ATRAC9, Sony's compressed audio codec used for music, voices and sound effects in PlayStation 4 and PlayStation Vita games, such as the snd0.at9 theme of a PS4 game. The audio sits in a RIFF/WAVE-style container that ordinary media players cannot play.
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
AT9 files carry Sony's ATRAC9 codec, built for low-latency game audio on the PS Vita and PS4. ATRAC9 decodes in hardware on those consoles and supports loop points for music. Game rips and modding tools produce .at9 files, which ordinary players can't open.
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 | AT9 | WAV |
|---|---|---|
| Developed by | Sony | Microsoft and IBM |
| File extension | .at9 | .wav |
| Compression | Lossy (ATRAC9) | None (PCM) |
| Size vs uncompressed WAV | About 1/10 | Same size (1:1) |
| Tags and cover art | Loop points | Basic text tags, no cover art |
| Best for | PS Vita and PS4 game audio | Editing, mastering, speech tools |
| Plays on phones and browsers | No, needs vgmstream | Yes |
USE CASES
Practical workflows where AT9 to WAV conversion is useful.
Remix PS4 and PS Vita music
Load the WAV into Reaper, FL Studio or Ableton Live to remix or sample a game track.
Edit a theme for a homebrew package
Decode a snd0.at9 to WAV, shorten or edit it, then encode it back with Sony's tools for your own PS4 package.
Edit a sound for a game mod
Modders can decode an .at9 voice line or effect, change it in an audio editor and re-encode it for the game.
Clean up dialogue for a fan video
Run noise reduction or level matching on game voice lines in Audacity or Adobe Audition, starting from uncompressed PCM.
Hear a looped track as a full piece
Music that loops over part of the track comes out with one more pass of the loop and a 10 s fade-out. A whole-track loop plays once.
Use game music as a video source
Import the WAV into Premiere Pro or DaVinci Resolve as a clean 48 kHz audio source for an edit.
Archive game audio as PCM
Keep uncompressed WAV copies of a game's .at9 files so they open in any audio software later on.
Re-encode to another format once
Use the WAV as a clean intermediate for FLAC, AAC or Opus in your own encoder, so the audio is compressed only one more time.
Sample sound effects
Producers can chop PS4 and PS Vita sound effects and voice clips in a sampler, which reads WAV directly.
Build a fan soundtrack album
Fans compiling a soundtrack can normalize and tag tracks starting from WAV instead of a re-compressed MP3.
SUPPORTED FILES

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
The file is damaged, isn't really AT9 audio, or was extracted with the wrong tool. Extract it again from the game files and retry.
03
WAV is uncompressed, about 10 MB per minute for 44.1 kHz stereo and more for higher rates or extra channels.
04
Truncated rips fail instead of giving partial audio. Extract the file again.
05
Those consoles use AT3. Use our AT3 to WAV converter.
06
Loops are rendered into the audio, not stored as markers.
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 AT9 into WAV on any device.
