Hello
I'm looking for a resonant filter that's switchable between lowpass,
bandpass and highpass and which has a traditional ADSR envelope
controlling it. I'm wanting something that can be used in JACK Rack or
something like that, or which could be used as a plugin in Ardour, in
order to process incoming audio in real time.
There are plenty of LADSPA filter plugins, but they all seem to be
either static or swept by an LFO or similar. I thought someone, at some
point, might have made a filter and envelope triggered by an incoming
signal, in the way that a synth's filter does.
It looks like all the building blocks are probably there in various
LADSPA plugins, but I can't figure out how you'd connect them together.
I'd also consider a hardware solution (but only a cheap one, as finances
are very tight at the moment) and in some ways it would have some
advantages. I thought there was bound to be a guitar stompbox that would
do that (and no doubt a cheap Behringer knock-off version as well!), but
so far I've not turned up anything suitable.
Does anyone have any suggestions -- either for software or cheap
hardware -- that would help me achieve what I want to do?
Thanks in advance
Q
Hi all,
Is anyone aware of any application as in the subject? With live I also
mean audio output from another (jack) source.
AFAIK there are only baudline [1] and freqtweak [2]. Baudline seem very
well done and it supports jack, but I personally find the vertical
scroll a bit awkward (personal taste) and it doesn't seem possible to
zoom to a specific frequency range or have two separate channel views.
Freqtweak also has a vertical scroll, and although it looks a pretty
cool software I can't seem to successfully select the jack source.
One sonogram software which really rocks is Sonic Visualiser [3] but (as
it's more intended for analysis and in fact does much more than
sonogram) it doesn't have live input.
Really I'd be happy with a simple horizontal scrolling sonogram ideally
with frequency zoom just to 'see' audio I'm working with (I know there
are very nice spectrogram applications, but for certain stuff I prefer
sonogram), e.g. in the style of the built-in sonogram of MAX MSP.
Suggestions, pointers et cetera appreciated.

Hi,
>From an Avid email I received today quoting an January article in
ProAudio Review:
"Laid to rest is Pro Tools LE [it will "no longer be developed,"
offers Avid — Ed]. Now there are Pro Tools and Pro Tools HD, and the
gap between the two has narrowed; Pro Tools M-Powered "is still a
current product, which hasn't been updated to v.9," explains Avid."
Seems to me the new Harrison product, and Ardour in general for the
more technically adept new folks potentially coming to Linux, is here
at a good time to address Avid not supporting the entry market as much
as they did (which wasn't much) during a better economy.
I wonder how we could evangelize Linux Audio more effectively to the
outside world?

For those how like the latest development from the guitarix project, I
will let you know that there are some new amp/tube models available in
our SVN repository. Lately suggested by guitarix friend merlinthegreen
we have reworked the drive function so that a value from zero now realy
is zero (bypassed) to reach clean sounds, all tubes can use now a cubic
non-linear distortion or a simple non-linear drive for the drive knob.
A new tube model (6DJ8) is added.
One more, Pete Shorthose have join the development team and have add
animation support to libgxw and committed animated Knobs and new switch
images for the head.
Those how wone have a first impress of what is going on, check out our
SVN repository. To build the head from SVN you need to add the configure
flag --build_head to ./waf configure.
have fun

I'm trying to use the drone synth plugin SO-666 with Ardour
I installed it from the KXStudio repo
but when I load one into Ardour the app crashes - as in: completely
shuts down
I also tried Qtractor to see if this was any more forgiving but it did
the same thing
I also tried the other two plugs SO-KL5 & SO-404 in both applications -
same thing again
here is the error message from my syslog:
Mar 10 08:36:16 kim-studio kernel: ardour-2.8.11[4577]: segfault at 10
ip ad650dc1 sp accd4b10 error 4 in libsosynth.so[ad650000+3000]
anyone else experience this?
my config is below:

Hello Q!
Hm, you could certainly d it with csound. :-)
Honestly, sorry for that remakr. :-) but the idea of Yoshimi mae me think:
You might be able to do it in Ingen, since it is - as far as I know - based on
the connection of LADSPA effects. So if Ingen allows for audio input, you
should be able to connect all the relevant plugin ports.
Good luck and goodbye

Hi,
I'm looking for a good online textbook/tutorial/reference site(s) to
learn the basics of DSP, preferably not specific to any language. Does
anyone have any pointers?
Cheers,
S.M.

On attempt to use device (or even just try 'cat /dev/hpet'), it is said, that device is busy. But jack has such option :/
I'm using kernel 2.6.33-rt. I can guess, that under rt kernel i should not use HPET directly, because it is used by system,
and so, may be referred via 'system'. But even if that, such way could bring some violations comparing to direct HPET usage.
May be indeed, HPET should be used directly only on non-rt systems?..
Btw, how i specified it: i have jack2 and ladish. Clock is specified via ladiconf. Clock parameter type is integer; yesterday nedko showed me a patch for jack, fixing this problem, where i saw order of variants in enumeration (hpet variant is '2').
