What is an AT3 file?

The .AT3 file extension is associated with a specific type of audio file format primarily used in the realm of multimedia and gaming.

These files contain compressed audio data and are commonly used for storing music and sound effects in various applications.

We will delve into the origin, history, file structure, technical specifications, advantages, disadvantages, and methods to open and convert .AT3 files across different platforms.

More Information.

The .AT3 file format was first introduced alongside the PSP in 2004. Its main purpose was to provide high-quality audio playback while conserving storage space, as the PSP had limited storage capabilities.

Over time, the format found its way into various Sony products and gaming applications, including PlayStation 3 and PlayStation Vita.

Origin Of This File.

The .AT3 file format was originally developed by Sony Corporation for use in their PlayStation Portable (PSP) gaming console.

It was designed to efficiently store audio data with minimal loss in sound quality, making it ideal for handheld gaming devices with limited storage capacity.

File Structure Technical Specification.

.AT3 files use a proprietary compression algorithm developed by Sony. They typically contain audio data encoded in the Adaptive Transform Acoustic Coding 3 (ATRAC3) format.

This compression scheme allows for high-quality audio playback with a small file size. .AT3 files may also include metadata such as track information and album art.

Here’s how to convert .AT3 files on different platforms:
