About formats

AMR (Adaptive Multi-Rate) is a compressed audio format optimized for speech, standardized by the European Telecommunications Standards Institute and adopted as a mandatory codec for GSM and 3G mobile networks. The codec dynamically switches between eight bit rates — from 4.75 to 12.2 kbps — depending on network conditions and background noise levels. When link quality drops, the encoder shifts to a lower rate, trading marginal clarity for transmission reliability. This adaptive mechanism is defined by the 3GPP specifications and represents one of the most widely deployed voice codecs globally, used in billions of mobile calls. The primary advantage is compression efficiency: one minute of AMR audio at 12.2 kbps occupies roughly 90 KB, practical for voice memos, voicemail, and MMS on bandwidth-constrained networks. Another benefit is built-in voice activity detection and comfort noise generation, reducing transmission during silence. While AMR is unsuitable for music due to its narrow bandwidth (300-3400 Hz), it excels at delivering intelligible speech under challenging network conditions.

AMB files contain audio encoded in Ambisonic B-format, a full-sphere surround sound technique conceived by Michael Gerzon during the 1970s. Unlike channel-based systems such as 5.1 or 7.1, Ambisonics captures a complete three-dimensional sound field using spherical harmonics — first-order B-format consists of four channels: W (omnidirectional), X (front-back), Y (left-right), and Z (up-down). This representation is speaker-independent, meaning one recording can be decoded to any loudspeaker arrangement or binaural headphones without remixing. AMB files typically store uncompressed PCM data and are processed by tools like SoX or specialized plugins. A core advantage is spatial flexibility — creators produce one master file that adapts to stereo, surround, or immersive playback. The format also scales elegantly: higher-order Ambisonics adds channels for increased spatial precision upon the same mathematical framework. With the growth of virtual reality, 360-degree video, and spatial audio for gaming, Ambisonics has experienced a resurgence, adopted by platforms like YouTube for immersive media delivery.
