About formats

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.
Initial release: 1975
WVE is the audio format native to the Psion Series 3 family of personal digital assistants, released by British company Psion PLC beginning in September 1991. These clamshell PDAs included a built-in voice recorder, and all dictation functionality relied on WVE files to store captured sound. Each file begins with the ASCII signature "ALawSoundFile**" followed by a minimal header, then raw A-law encoded audio sampled at 8 kHz — a rate inherited from digital telephony standards. At 8000 bytes per second, a one-minute recording occupies just 480 KB, which was essential given that Psion devices stored data on SRAM cards typically ranging from 128 KB to 2 MB. The A-law encoding provides reasonable speech clarity within these tight storage constraints, prioritizing intelligibility over high-fidelity reproduction. WVE files can be converted to WAV or other modern formats using SoX, Awave Studio, or specialized Psion file utilities. While the format is firmly a product of early-1990s handheld computing, it holds historical significance as one of the first audio recording formats designed for pocket-sized consumer devices. Collectors and researchers studying mobile computing history occasionally encounter WVE files when recovering data from legacy SRAM media.

Frequently Asked Questions

Why convert AMB to WVE?

WVE provides Psion handheld audio format. Converting AMB brings your spatial recordings into a format usable for retro PDA and handheld audio.

What opens WVE files?

Psion devices, EPOC emulators, SoX can open WVE files for playback and editing without special plugins.

Does the spatial effect carry over?

AMB contains Ambisonic B-Format spatial data. Converting to WVE renders the audio to standard channels — the 3D spatial encoding is flattened.

What is AMB format?

AMB stores Ambisonic B-Format audio for VR, 360-degree video, and immersive spatial sound production. It is a specialized surround format.

Can I batch convert AMB files?

Upload several AMB recordings and convert them all to WVE at once — process your spatial audio collection efficiently.
