# AMBCHAN

how to help

A Perl script
that:

- Converts channel notations.

`ambchan 12` *or* `ambchan 3,0`
*or* `ambchan K`

all return the same output, that is that channel described
by:
- Ambisonic channel number (ACN) (e.g. 12)
- Order and range (
*(l,m)* notation) (e.g. (3,0))
- Channel letter (where one exists) (e.g. K).

The equation for the associated spherical harmonic
is also returned for lower order channels. (This is in LaTeX
notation. The advantage of removing any ambiguity from
the formula is replaced by a not very readable style!)
- Converts notations for
*groups* of channels (for
example mixed order groups).

`ambchan hv=3,2` *and* `ambchan hv=ffh`

will each return both values. That is (H,V) notation and
Malham notation.

Also returned are a listing of all the channels in such a
grouping and the total number of channels.

Output is to the terminal.
Should work on any platform
with Perl installed, thusfar tested on Linux.
## Sample outputs

*Under construction.*
