B-Format Sequence for Ambisonic Channels

Ambisonic StandardsThe order in which to present ambisonic channels has been the subject of various approaches. These pages present a standardised method, where each channel is given a unique number out of a set of consecutive integers, starting with 0...

Ambisonic G-format Channel Ordering

Ambisonic StandardsAmbisonic decoders produce ‘speaker feeds’. Typically these are for local use (to be fed to a sound card). Even so, a standard order will minimise user configuration. G-format files can also be made and distributed. This breaks the p...

Ambisonic Channel Formats

Index pageAudio files associated with ambisonics are multi-channel files. The channels can though be of any number. To allow transfer of files (or data streams) from one user to another, or from one software application to another, it is essential that...

Notes on Spherical Harmonic Equations

Index page GlossaryThere are various possible ways of presenting equations for spherical harmonics. These notes try and explain the choices made here. Firstly as the interest is in ambisonic audio only, real (as against complex) equations are presented...
