Place the executable into a dedicated folder (e.g., C:\at9_project ). Place your source .wav file into the same folder. 2. Opening the Command Line Hold Shift and right-click inside your project folder.
ATRAC9, an abbreviation for "Adaptive Transform Acoustic Coding 9," is a proprietary audio codec developed by Sony for its PlayStation consoles. It first saw widespread use on the PlayStation Vita, later becoming the standard for the PS4 and PS5.
Converts .at9 files back into standard .wav files, allowing developers to listen to or edit the audio on standard PCs.

To create a custom sound asset for use inside a PlayStation game engine or system theme, use the -e flag coupled with targeted quality parameters: at9tool.exe -e -br 144 input_audio.wav output_audio.at9 Use code with caution.
To convert a game's compressed background track into a standard Windows-playable file, use the -d argument flag: at9tool.exe -d input_audio.at9 output_audio.wav Use code with caution. 2. Encoding .wav to .at9
at9tool.exe -c -d 123456
This tool is often part of official Sony SDKs but is widely distributed in "modding starter kits" for PlayStation platforms .

For background music tracks that need to repeat seamlessly, developers append loop arguments: at9tool.exe -e -loop 44100 88200 input.wav output.at9 Use code with caution.
