FSB (FMOD Sample Bank) is a proprietary audio container format used by the FMOD audio engine to store compressed or uncompressed sound samples. It is commonly used in video games to bundle multiple audio clips into a single efficient file for runtime playback and streaming.
An M4A file is an audio file created in the MPEG-4 format, a multimedia container format used to store compressed audio and video data. It contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC).
