Fwd: Ambisonics / Kokkini Zita

[rosea grammostola]

Hi,

Linuxaudio has some strong and special points. One of them is 
Ambisonics. Would be nice if people can use Debian to work and/or 
experiment with Ambisonics. The good point: most of the packages needed 
for Ambisonics are in Debian already! Great job!

Two are missing afaik:
- Drc http://drc-fir.sourceforge.net/
- TetraCal (Tetraproc is in Debian, not sure about TetraCal)

By the way; most packages of Fons Adriaensen are often useful and 
powerful: quality software. Most packages of him are in Debian, but 
today he recommended an package on the LAU mailinglist which is not in 
Debian yet: jnoisemeter 
http://kokkinizita.linuxaudio.org/linuxaudio/index.html

See also message below about Ambisonics.

Best regards,

\r

absolutely essential.

essential for production, but not for listening.

not related to ambisonics. but dead useful.

not essential either. but very much recommended, as it contains
configurations to encode ambi into uhj stereo and back. for ambi use,
you want to include fons' separate "reverbs" package, which contains
some very nice b-format IR reverbs.

>  drc

unrelated. it only does room and speaker correction.
it's probably my fault it got included in the list, since i once
described how to set up a diy ambi rig that includes drc. but that's
optional.

>  aliki

not strictly related, although helpful if you want to create your own IR
reverbs for jconvolver (or any other convolver), or if you want to
measure your room and/or speakers to perform DRC.

>  zita-rev1

very helpful.

>  probably: non-mixer

or any other lightweight alternative to ardour, if it's just about
signal routing.

if the question is "what do i include in my distro", then by all means
add all the software you mentioned. if the question is "what is the
minimum software stack i need to play around with ambisonics, then keep
it simple. in any case, you may want to include mplayer, as it's one of
the few players that does multichannel correctly (at least up to 8
channels) and will let you enjoy those soundfield recordings out on the
web without having to import them into an ardour session.
