- Description
- A lossy file format used to compress speech in Global Standard for Mobile (GSM) telecommunications. It is very effective for reducing audio file size. However, encoding and decoding audio signals severally is discouraged as the final product will have a lot of noise. Popular with some voice mail software but it is CPU intensive.
- Audio format that uses MPEG-1 Layer II compression to reduce the file size; mainly replaced by the ubiquitous .MP3 format, but is still used for digital radio and digital television broadcasts.
