What is the difference between .avchd and .sou?

Description: AVCHD (Advanced Video Coding High Definition) is a file format designed for recording and playing back high definition video. It is commonly used in digital camcorders and cameras for capturing HD footage. AVCHD leverages the MPEG-4 AVC/H.264 video compression codec, which efficiently reduces file sizes while preserving high-quality video resolution, and supports both Dolby AC-3 and linear PCM audio codecs for high-quality sound.; 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.
