Ambisonics | Channel Count
The number of ambisonic channels
present in periphonic, pantophonic and
mixed-order ambisonic files.

Glossary

The term file used on this page
can equally well mean stream (for
streaming Web applications), &hellip or
just the ensemble of jack leads transferring
data in studio usage.

For a file described by (H,V) then the total number of channels present is given by the following table.

H is the order of the file (the highest degree), V the highest periphonic degree (thus V must always be less than or equal to H). (Acknowledgements to Fons Andriaensen for the (H,V) notation.)

The table is complete upto 256 channels. (Whilst the upper right of the table is by definition empty, the lower right has just not been completed — all the blanks in the lower right have values greater than 256).
