- 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.
- An M4A file is an audio file created in the MPEG-4 format, a multimedia container format used to store compressed audio and video data. It contains audio encoded with either the Advanced Audio Coding (AAC) codec or the Apple Lossless Audio Codec (ALAC).
