Adaptive Multi-Rate Codec (AMR) is a file extension used primarily in voice applications, including VoIP, audio messaging, and mobile phone telephony. Originating from the European Telecommunications Standards Institute (ETSI) in 1999, AMR files enable efficient compression and transmission of speech audio. The codec dynamically adjusts bit rates during transmission to optimize audio quality and network capacity. Its efficient bandwidth utilization and compatibility with various communication standards have made AMR a preferred choice for many modern communication systems.
M4A, an acronym for MPEG-4 Audio, is a file extension used to represent audio files encoded with Advanced Audio Codecs (AAC or ALAC) as part of the MPEG-4 format. Introduced by Apple in 2001, M4A was designed to improve upon the MP3 format by offering superior audio quality and smaller file sizes. Widely used in digital music distribution, M4A files are known for their efficient compression and lossless audio options, making them a preferred choice for music enthusiasts and professionals in the tech industry.
