The MPA file format, standing for MPEG-2 Audio File, is designed to store audio data compressed using the MPEG-2 Audio coding standard. This format is a successor to the MPEG-1 standard, offering enhancements like improved audio quality and support for multiple audio channels, thus enabling surround sound experiences. MPA files are commonly used for both music and video soundtracks due to their efficient compression, which preserves sound quality while reducing file size significantly.
A WEBM file is a compressed video saved in the WebM format, an open, high-quality video standard. It stores video compressed using VP8 technology and audio compressed using Ogg Vorbis compression. WEBM files are commonly used for delivering online videos using the HTML5 <video> tag.
