Free online AT3 to WAV converter

Source format overview

AT3 is an audio format commonly associated with Sony ATRAC3 compression. It was widely used on PlayStation Portable (PSP) games, system files, and some Sony media applications. AT3 files are typically compressed audio intended to save space while keeping acceptable sound quality, which makes them useful for game soundtracks, voice clips, and in-game effects.

Target format overview

WAV is a standard uncompressed audio container, usually storing PCM audio. It is one of the most compatible audio formats and is supported by nearly all editors, players, and operating systems. The main advantages of WAV are high compatibility, easy editing, and preservation of audio without additional compression artifacts. It is commonly used for audio production, archiving, and further conversion to other formats.

How to convert at3 to wav

The most reliable way to convert AT3 to WAV is with a desktop audio tool that supports ATRAC3 decoding. A practical choice is FFmpeg, which can decode many AT3 files directly.

1. Install FFmpeg on your computer.
2. Open a terminal or command prompt in the folder containing the AT3 file.
3. Run a command such as ffmpeg -i input.at3 output.wav.
4. Wait for the conversion to finish, then open output.wav in an audio player or editor to verify the result.

If you prefer a graphical workflow, you can also use audio editors or converters that support ATRAC3 input. In such programs, open the AT3 file, then choose File → Export or File → Save As and select WAV as the output format. If you want a quick browser-based option, you can convert the file on 101convert.com for free without installing any software.

Quality and compatibility notes

Converting AT3 to WAV does not restore lost audio data; it only decodes the compressed audio into an uncompressed format. Because AT3 is already lossy, the resulting WAV will have the same audible quality as the source, but it will be much larger in file size. Some AT3 files may contain metadata or be packaged in game-specific containers, so not every file will decode correctly in every tool. If FFmpeg fails to open the file, the AT3 may be a variant that requires extraction from its original container first.
