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.
The .sou file extension is associated with SBStudio II, a music composition and editing program. A .sou file represents a SBStudio II Sound File, which contains audio data used by the software. These files are typically used to store instrument sounds or sound effects that can be integrated into music tracks created within the SBStudio II environment. The format is designed specifically for use with the SBStudio II software, making it a specialized audio file type for music production within this specific program.
