Audio quality is determined by the AD and DA converters and their clocks, not by any digital interface circuits such as the Envy24. It seems that Ralf went to some people and asked before posting here and thus made the attempt to be informed before writing here. If one is a newbie in this field (i.e not a developer or engineer) i think that asking basic questions is to be expected. Quite a few of us started out as 'audiophiles' and have all sorts of bad, misleading marketing information about how soundcards work. Ralf's posts strike me that way.

[LAD] You guys don't make nearly enough sense as you should to me :")
Fons just wrote "as far as i'm concerned, it would be cool to have some help creating a "hybrid" matrix like i described to bearcat, to avoid having to run separate ambdecs for tops and subs. the most important thing would be another gain coefficient to match the subs to the tops, similar to what you already have to tweak the two psychoacoustic bands." gain coefficientwhat? I know that makes sense to the lot of you but not to me. I'd like to fix that. I love sound and i'm genuinely interested in sound theory, audio recording, the effects of sound on the body and ambisonics. My problem is that some of the things said on this list come across as Frontier Gibberish because though i have the background in it as a hobby i don't have the training or education (mine is in computer programming not audio). Reading up on ambisonics lots of it is technical and i'd like to be able to understand it. So i want to educate myself. Does anyone have any suggestions for books or what have you that i could pick up to give me a basic feel for how all this works, basic accoustic sound theory? Should i pick up a book on algebra 2 first? (i'm not a math-wiz. I finally passed Algebra 1 on the 2nd try). If i were to look at a college course for what books they use, what course titles would i be looking for? I probably won't get to the knowledge level of Fons or Jorn by reading books an messing around with my equipment, but i'd sure like to try. For what it's worth English is my first and last language when talking about reading material. Thanks folks. I appreciate it. ___ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
[LAD] linux and ambiophonics
Folks, Is there anyway to set up an ambiophonic (not to be confused with ambiosonic decryption) filtering on a Linux system? I'd prefer 4 channel if possible. I'm aware of brutefir, but i doubt i have the knowledge to set up so complicated a system equation by equation. Are there brutefir scripts out there for it? Anyone know of a ambiophonic ladspa plug in or something?

Yes. You need to add a softvol control. The following file will give you
one called "Master" and set up dmix which will allow you to play more then
one stream at once. This file assumes your card is card 0. If not change
the "pcm "hw:0,0" and "card 0" lines. Note that dmix is hardset to 48khz
so you will need to change your sample rate in your card settings to match
or else things will sound too slow or too fast.
Here's my /etc/asound.conf.
pcm.dmixer {
type dmix
ipc_key 1024
ipc_key_add_uid false
ipc_perm 0660
slave {
pcm "hw:0,0"
rate 48000
format "S32_LE"
period_time 0
period_size 1024
buffer_time 0
buffer_size 8192
#was 5120
}
}
pcm.softvol {
type softvol
slave.pcm "dmixer"
control {
name "Master"
card 0
}
}
# change default device:
pcm.!default {
type plug
slave.pcm "softvol"
}

When i went down my local (ok, only) studio to have some LPs transferred to CD the studio owner and i were talking about this very subject. He told me that one day he bought a new mixer to replace his aging one. He set it next to his old one and got it ready. The phone rang. He spent the next few hours experimenting with it, and was happy with the differences it made in the sound he was trying to achieve. However, he had forgotten to turn it on. I'm sure this isn't the only such story out there. If a person can fool themselves into believing that such a piece of equipment is even functioning, how much difference can it make? As a matter of fact, i think he returned the mixer and stuck with his old one. Bearcat M.
