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.
A 3GP file is a multimedia file saved in an audio and video container format developed by the 3rd Generation Partnership Project (3GPP). It stores video and audio streams that are transmitted between 3G mobile phones and over the Internet.
