The AMR audio format is mostly used to store and transfer speech-based audio files such as call recordings, voice notes, and VoIP calls. The format is based on advanced technologies like Comfort Noise Generation (CNG) and Voice Activity Detection (VAD) that would optimize the speech in the audio format and minimize any background noise.
