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.
AC3, short for Audio Codec 3, is a file extension developed by Dolby Laboratories for digital audio compression. Primarily utilized in home theater systems, DVD, Blu-ray, and broadcasting, it delivers up to 5.1-channel surround sound. Introduced in the early 1990s, AC3 revolutionized audio experiences by providing high-quality sound with efficient data compression. This codec enhances user experiences with its immersive audio capabilities, making it a standard in the industry.
