Convert FRG to AT3

Understanding FRG and AT3 file formats

FRG files are typically associated with video games, especially those developed for Sony PlayStation platforms. These files often contain audio data or sound effects in a proprietary format used by specific games. On the other hand, AT3 (ATRAC3) is an audio codec developed by Sony, commonly used in PlayStation Portable (PSP) games and other Sony devices for compressed audio playback.

Why convert FRG to AT3?

Converting FRG files to AT3 format allows users to extract and use game audio in a more widely supported format, especially for playback on Sony devices or for use in custom game mods.

How to convert FRG to AT3

Since FRG is a proprietary and less common format, direct conversion tools are rare. The typical process involves two steps:

1. Extract audio from the FRG file using a specialized tool.
2. Convert the extracted audio (often in WAV or another standard format) to AT3 using an audio converter.

Recommended software for conversion

• VGMToolbox: This tool can extract audio data from many proprietary game formats, including some FRG files.
• GoldWave (with ATRAC3 plugin): After extraction, use GoldWave to convert WAV or other audio files to AT3. Use File → Save As and select ATRAC3 as the output format.
• HiMDRenderer: Another option for converting standard audio files to AT3 format.

Step-by-step conversion process

1. Open VGMToolbox and use the extraction tools to locate and extract audio from your FRG file.
2. Save the extracted audio as a WAV or RAW file.
3. Open GoldWave and load the extracted audio file.
4. Go to File → Save As and choose ATRAC3 (AT3) as the output format.
5. Adjust encoding settings if needed, then save your new AT3 file.

Tips and considerations

• Not all FRG files are supported by extraction tools; results may vary depending on the game.
• Ensure you have the ATRAC3 codec installed for GoldWave or your chosen converter.
• Always keep backup copies of original files before conversion.
