An AMR (Adaptive Multi-Rate) file is a compressed audio format commonly used for encoding speech and voice recordings. It was originally developed for mobile phones and communication devices to efficiently transmit and store audio while conserving bandwidth and storage space. AMR files utilize a variable bitrate encoding scheme, meaning the compression rate can adapt to the complexity of the audio, allocating fewer bits to simpler parts and more bits to complex segments, which results in a smaller file size without significant loss in audio quality for speech-related content.

AMR files are prevalent in telecommunications, as they are suitable for voice calls and voicemail messages, where the focus is on clear and intelligible speech rather than high-fidelity audio. The format is also employed in various applications like voice recordings, voice notes, and audio messaging in mobile devices. Despite its efficiency for speech, AMR may not be the best choice for music or other high-quality audio recordings, as it sacrifices some audio fidelity to achieve compression, making it less suitable for music and other audio content that requires intricate details and richness in sound.
