ahh cheers yes i know freqtweak, very yummy...
i was kinda thinking along the lines of plugins tho... afaik you cant
use freq. as a plugin as yet?... the nicest thing about spektral delay
is that i can use it as a plugin in live, so while i have all that other
stuff going i can mangle my sounds to my hearts content... dunno that i
could use freq. all of its own for a set. im looking at moving to using
spiralloops tho instead of live, as it uses ladspa plugins...

This one is a very experimental release, hence the .0, its even more
likly to cause pain and death than other releases :)
I've attached a list of the plugins against what state I think there in,
for the people who want to help by testing, it should save you some
time by weeding out the very simple and definatly broken ones. Please test
against this version, not previous ones.
It includes rough support for gettext, so, in theory the plugins can be
localised without support from hosts. If people want to provide
translations, look in the po directory, I think theres everything you
need, but I've never used gettext before, so I may have messed up.
I've done some significant work on the compressors, most notably SC4,
(stereo, no sidechain) which has a continuously variable RMS/peak control
and a magick 'fast' mode: when the attack time is set to very low it
behaves more like a limiter. This feature seems to be present on a lot of
hardware compressors.
SC4 now has ID 1882, so you should move away or delete the old sc4_1434.so
file. It wasn't strictly neccesary to rename the file, but it would be
confusing (to me) if I didn't.
The others all have slightly faster responses and less damping after I
found out that you were /supposed/ to get pumping with fast envelopes :)
I ran through them with demolition
(http://www.ecs.soton.ac.uk/~njl98r/code/ladspa/) and fixed a lot of crash
bugs, so things should be more stable once the major code changes settle
down.
There is still no support for the beta FFTW (version 3), or OSX. I wanted
to get this release out this week, they should be supported in the next
version.
Summary:
please test, especially the compressors
translations welcome

Since the UI is generated by the host, does this rule out the possibilty
of a LASDPA plugin that would allow for creating custom dynamic curves
using a spline modeling UI? I've always liked the dynamics tool from
Cool Edit Pro that allows this creation of custom curves and assigning
them to user specified bandwidths. Is something like that possible the
way LADSPA currently works?

Hello,
While hints to this have been here before, I just want to make sure...
Is there NO way to use the SB Live S/P DIF output under Linux?

Subject: [linux-audio-user] LADSPA Taxonomy
Hi all,
After the LAD Conference and using apps which used the lrdf taxoomy
(putting plugins into categories) code it became obvious the the current
taxonomy wasn't really useful.
the current taxnomy looks like:
Utilities
Generators
Oscillators
Simulators
Reverbs
Time
Delays
Phasers
Flangers
Chorus
Reverbs
Frequency
Measurement
Filters
Lowpass
Highpass
Bandpass
Combs
Allpass
EQs
Parametric
Multiband
Pitch shifters
Amplitude
Amplifiers
Waveshapers
Modulators
Distortions
Dynamics
Compressors
Expanders
Limiters
Gates
This makes a certian amount of sense from a theoretical point of view, but
isn't much use when you're trying to find a compressor.
So, we need to deine a taxonomy that is more useful to users.
I recon that something like this is a good start, but feedback would
really help:
Utilities
Generators
Oscillators
Delays
Phasers + Allpass
Flangers
Chorus
Reverbs
Filters
Lowpass
Highpass
Bandpass
Combs
EQs
Parametric
Multiband
Pitch shifters
Modulation
Distortion
Amp effects
Waveshapers
Dynamics
Compressors
Expanders
Limiters
Gates
Feel free to suggest changes to make it easier to use. I can drop in the
new taxonomy without changing any code. As soon as we decide on a new
structure I will distribute a new .rdfs file then you can just copy it
over the old one and try it out.

Hi Frank,
What's that Mad Scientist stuff that you're using with
PD? If it's DIY, do you have more photos and docs
online?
The photo on LAD just isn't revealing enough--me, must
know more. :)

Hello,
I'm sitting on a deal for a Peavey PC 1600, and I'm wondering if anyone
out there has any experience using it with Linux and specifically ardour
w/ envy24 based cards.
It seems like a cool device, and would sort of act as a poor man's mixer.
-Rich
Hi,
I've decided to switch from my cmipci-based DiO 2448 to a envy24-based
soundcard. Now I have three choices of used gear:
1) Terratec EWS88MT - 400 euros
2) Terratec EWS24/96 - 130 euros
3) Midiman Delta 66 - 230 euros
some considerations:
* I've no special need for s/pdif
* ardour would be the target app
* 4 simultaneous I/O channels would be nice
* I'm a little on budget
Any hints?
Thank you
P.S. with EWS24/96 it's possible to record reliably 4 channels at once?

Hi all,
I have got the second alpha release coming on Sunday.
Audio* is a project to create real-time music software as Open Source. I
announced the project a week ago. http://audiostar.sourceforge.net
There is plans to make a Reason-like program next for Linux. I have
moved to Linux for good. I don't even notice I am using it anymore,
there's no differece between using Linux or Windows to me anymore,
except one is free and get's better latency.
Tekno Composer is a copy of Rebirth without copying it. (A project named
Reborn tried and was pulled because of copyright problems). Tekno
Composer features a Silver Mojo synthesizer, a 16-voice polyphonic drum
and sample stack wavetable synthesizer, and a demented Loop machine I am
still having problems getting to sync properly but should be fixed by
release tommorow.
It is just as good as Rebirth almost (it needs features still not
implemented). I have plans to make a Rebirth file loader so you can
listen to Rebirth files on Linux since Propellerheads never supported
Linux in any way, although it will not be able to play them exactly the
same as Rebirth (remember it's not a clone of Rebirth, it is just an
alternative that sounds pretty close to it *snicker*, I think it's
better than a 303... more toys to play with).
Silver Mojo is a monophonic, 3 oscillator synthesizer with plenty of
features and toys to make cool sounds. It was more or less designed to
copy a SH-9, an M-100, Korg MS-20, and Mini Moog, but with a step
sequencer like a 303. That is why there are 3, and one is label SUB but
you can make it up to 2' pitch if you want. It has two LFOs which can be
synced to the tempo. One goes to the oscillators (PWM and Vibrato) and
one goes to the filter. It also has Tremolo and Ping/Pong panning which
will be syncable to the tempo soon; I am real busy on other stuff right
now. It has all the basic F/X pedals you could want, and one custom Quad
Chorus I created which is a multi-tap chorus box and sounds very fat. It
has a 64-step sequencer, like a 303, but a little different. It is not
an emulator, and does not intend to be one, because most projects that
copy Roland gear or Rebirth get into trouble with them.
The drum machine is a 16-voice 16-stack polyphonic wavetable
synthesizer. With some more work it will be a synthesizer in it's own,
much like the stacking synths of the 80's, except you can use any wave
form, not just a period of a wave in it. You do not really need to use
it as drum machine if you load other samples in it. It is very much like
an 808/909 programming wise, 16-step sequencer. Right now it uses a very
primitive text file to load the samples... but in the future it will be
an XML file format.
The Loop machine (will) allow you to sync samples/loops to the drum
machine beat. You can loop or do one-shot synced to a step on the drum
machine. It also has a barbaric text file to load the samples. That too
will be XML in the future. I can only do so much in a weekend.
It should run on a P2-450 but I have only tested it on a P4 2.0 and a P3
550 so far. The goal is for it to run on a Pentium Pro 200 Dual system
as the base line. It is not designed for speed but for the highest
quality sound possible that I can figure out. I do not have oversampling
enabled yet it is not fast enough for it.
You will need FLTK 1.1.X and Port Audio v18. I have an ALSA driver in
there, but I have not confirmed it works yet it is a rip from my other
project. There will be Jack drivers as soon as I can get Jack to startup
as a daemon on my system.
It is still Alpha and not all of the program has been implemented yet.
The project could use one dedicated programmer to help implement
features. I can only do so much at a time by myself.
Although Rebirth isn't any big deal now, I wouldn't feel complete if I
didn't build a program that could mimic it without infriniging on
copyrights in any way :)
I'd like to thank Julius Orion Smith from CCRMA for all of his papers,
and Tom Stilson for analyzing the Moog VCF transfer function, and Perry
Cook for STK. It took about 6 months of intense reading of them ( I read
the BLIT paper 100 times), but I learned alot and because of that I was
able to make a program like this. I thought it was fun, but frustrating
at times, getting to the point I could make something cool with all that
technical information. Even though I've been programming for 10 years I
didn't know alot about DSP and DSP is not something you learn in an
afternoon (unless you are a super-genius type). So many thanks to the
awesome people who took the time to explain the math and formulas, and
also thanks for Music DSP for the many code snippets. Also I'd like to
thank Alex (something) who made the DigiFX, where I learned how to code
many of the sound F/X. Big thanks and much gratitude to you all. I hope
I can return some cool stuff in exchange for that knowledge. That's the
reason I am making it Open Source and free to say thanks for teaching
me.
Thanks list!
