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.
Opus, associated with Opus Audio, is an open, royalty-free audio codec designed for high-quality voice and music streaming. Introduced by the Internet Engineering Task Force (IETF) in 2012, it adapts seamlessly to various applications like VoIP, videoconferencing, in-game chat, and live music performances. Known for its versatility, low latency, and high compression efficiency, Opus is widely adopted in modern communication platforms and web applications, making it a cornerstone in contemporary audio technology.
