What is a FEV file?

FEV files mostly belong to FMOD Studio. FEV files are used by FMOD Studio to store event audio data for interactive applications like video games. They are based on the RIFF format, which organizes data into chunks to keep event details clear.

Purpose: Define triggers and parameters for audio events.

Functionality: Manage how audio plays by controlling factors such as volume, pitch, and timing.

Integration: Work alongside other FMOD files (for example, sample banks) to shape dynamic sound environments.

FEV file format:

The file format, which is the arrangement and type of data in a file, determines which program can open the file. The file format can be deduced from the file extension and the signature. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the FEV files:
