About formats

WMA (Windows Media Audio) is a family of proprietary audio codecs developed by Microsoft and first released in 1999 as part of the Windows Media framework. Created to compete with MP3 and AAC, WMA Standard uses perceptual coding to deliver what Microsoft claimed was near-CD quality at bitrates as low as 64 kbps — roughly half the data rate MP3 typically needed for comparable results. The codec family grew to include WMA Professional for surround sound and high-resolution audio, WMA Lossless for bit-perfect archival compression, and WMA Voice optimized for spoken content at very low bitrates. Deep integration with Windows, Windows Media Player, and the Zune ecosystem gave WMA a strong distribution advantage throughout the 2000s, and digital rights management (DRM) support made it attractive to online music stores of that era. Encoding and decoding are handled natively by Windows, requiring no third-party software for playback on any Windows machine. Cross-platform support has improved through libraries like FFmpeg and GStreamer, though WMA remains less universally compatible than MP3 or AAC on non-Microsoft devices. The format still appears in legacy media libraries, though newer codecs have largely taken its place for streaming and portable use.
Initial release: 1999
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

Frequently Asked Questions

Why convert WMA to AMB?

AMB stores Ambisonic B-Format for VR and 360-degree audio. WMA cannot be used directly in spatial audio workflows.

What opens AMB?

Reaper with ambisonic plugins, Audacity, VLC, and spatial audio tools from Meta and Google handle AMB.

Does AMB create surround?

AMB is a container — true ambisonics requires multichannel spatial source recordings.

Is the conversion lossless?

AMB stores uncompressed PCM — WMA is decoded and stored without further compression.

Can I batch convert?

Upload multiple WMA files and wrap them all in AMB containers simultaneously.
