Ambdec-0.7.1  25 Aug 2018
-------------------------

Maintenance release.


Ambdec-0.5.1  11 Sept 2011
--------------------------

Changes
-------

* This release supports any format up to full 3rd order,
  including mixed order schemes such as e.g. 3h1v (W, X,
  Y, Z, S, T, U, V, N, O, P, Q) and not just 3h1p (W, X,
  Y, Z, U, V, P, Q). The 'hv' forms are really superior
  as they preserve azimuth resolution at any elevation,
  while the 'hp' form is just the sum of a higher order
  horizontal decoder and a lower order periphonic one.
  
* The matrix and speaker views in the config window have
  gone. There is really no point in editing high order
  matrices manually. You can still edit the preset file
  which uses a textual form of OSC.

* The config window shows a graphical representation of
  the input signals expected by a preset. All these signals
  must be provided for correct results, and all others will
  be ignored.

* Spaces in jack port names are accepted. Use either single
  or double quotes, or escape the spaces as '\ '.

* Some new presets, e.g. for a 'cube+faces' (14 speakers)
  which works great for full 2nd order. Some others have 
  gone. If you need anything specific just ask.

* The manual has not yet been updated, but if you used
  ambdec before you won't need it.


Compatibility with existing preset files
----------------------------------------

This release introduces preset file version 3 which replaces
the H and V order numbers with a channel mask. It also reads
version 2 presets but *not* version 1.

There should be very few version 1 presets around, but due
to a bug in makedec (the program I use to design decoders),
there are many version 2 files which are incorrectly tagged
as version 1. Previous releases of ambdec didn't mind the
error, but this one does. Fortunately it's easy to correct
such files. If you have a preset that has '/dec/hor_order'
and '/dec/ver_order' statements then it is a version 2 file,
and you can just change '/version 1' to '/version 2'. This
will make the preset usable by the current release.

Note that if you change anything in the config window and
save the changes, the preset will be saved as version 3.


Enjoy !
