About formats

AVI (Audio Video Interleave) is one of the oldest and most recognized multimedia container formats, introduced by Microsoft in November 1992 as part of its Video for Windows technology. Built on the Resource Interchange File Format (RIFF) structure, AVI interleaves audio and video data in alternating chunks, allowing synchronized playback without requiring sophisticated stream management. The format is codec-agnostic, meaning it can hold video compressed with virtually any codec, from early Cinepak and Indeo to modern DivX, Xvid, and H.264 streams. This flexibility contributed to widespread adoption across personal computers throughout the 1990s and 2000s. One notable characteristic is a straightforward internal structure that makes AVI files relatively easy to edit and process at the binary level compared to more complex modern containers. AVI also supports multiple audio streams, enabling multilingual content within a single file. However, the original specification has limitations, including a 2 GB file size ceiling in older implementations and no native support for variable frame rates or advanced subtitle formats. The OpenDML extensions (AVI 2.0) addressed the size limitation by allowing files to exceed the original boundary. Despite being decades old, AVI remains one of the most universally recognized multimedia formats and is still widely supported by media players and editing tools across all major operating systems.

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.

Frequently Asked Questions

Why convert AVI to AMB?

AMB is the standard for ambisonic B-format spatial audio. Converting AVI audio to AMB opens doors to 3D sound, VR, and immersive audio projects.

What software uses AMB?

Reaper (with ambisonic plugins), Ambisonic Studio, VVAudio, and various VR audio toolkits read and process AMB B-format audio files.

Is AMB used in VR?

Ambisonic B-format is fundamental to VR and 360-degree audio. AMB files provide the spatial audio data needed for immersive sound experiences.

What channels does AMB contain?

B-format ambisonics uses W, X, Y, Z channels representing omnidirectional and directional components of the spatial sound field.

Does this extract only audio?

Yes — the video is discarded and only the audio stream from your AVI is extracted and output as ambisonic B-format data in the AMB file.
