About formats

AC3 is the file format associated with Dolby Digital, a perceptual audio coding technology from Dolby Laboratories. This lossy format encodes up to 5.1 channels of surround sound (left, center, right, left surround, right surround, and LFE) into a bitstream typically ranging from 192 to 640 kbps. The algorithm applies a modified discrete cosine transform with psychoacoustic analysis to discard audio information below the threshold of human perception, producing compact files without obvious quality loss. AC3 became the mandatory audio standard for DVD-Video and is widely used in Blu-ray discs, digital television broadcasts (ATSC), and streaming delivery. A primary advantage is multichannel surround capability, bringing cinematic spatial audio into home theater systems. The format also maintains excellent dialogue clarity through its dedicated center channel, ideal for film and television content. Widespread hardware decoder support in receivers, TVs, and set-top boxes means AC3 audio plays back reliably across an enormous installed base of consumer electronics.
Developer: Dolby Laboratories
Initial release: 1991
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.
