Hi all,
I've posted gwc-lib on:
http://gwc.sourceforge.net/
This is an EXTREMELY crude release from the standpoint of documentation
at least, (and it took *forever* to get this far), and ..., but I want
to allow for input into the API.
It so far only includes the denoising algorithm. I do plan to include
the declicking and decrackling algorithms.
What got me motivated was 3 things:
1) Conrad Parker's intitial query into getting the algorithms into
sweep, and subsequent private emails helping me understand many issues.
2) Erik de Castro Lopo's release of Libsamplerate
3) Paul Davis' great post (spurred by libsamplerate) on linux-audio-dev
about how sharing these basic algorithms in a library format has really
made it a better world for all of us:
http://eca.cx/lad/2003/01/0006.html
In theory, there are only 2 files you need to look at to start playing
around - gwc_lib.h which describes the API (sorta), and denoise.c, which
is an example of how to use the algorithm. The basic idea is you
initialize the algorithm with parameters, feed it noise samples via
buffers, then start using it by writing and reading buffers. There
appears to be a small performance hit by using the buffers on the order
of 10%.
If you've a mind, please grab it and let me know how it goes. Fire back
ideas about the API. And, no, I'm not gonna LADSPA-ize it.
Cheers,
Jeff Welty
I'm trying John Hall's book Programming Linux Games, which recommends
using libsndfile to load sound files. Unfortunately, the API has changed
since the book as written, and I can't seem to get projects to compile
with it now. There don't appear to be any instructions on the library's
homepage about linking.
Hall just says to compile the project with the -lsndfile flag. This
doesn't seem to work now - the resulting project doesn't link the object
in. The library does seem to be correctly installed
I found a message from the library's author
http://www.eca.cx/lad/2002/Mar/0311.html
which says to link the program with
gcc `sndfile-config --libs` file1.o file2.o -o program.
I don't seem to have the sndfile-config utility, which was suppoed to
get installed along with the library.
Running ./configure created makefiles in some of the subfolders in the
installation folder. I'm mainly interested in the examples folder, but I
get errors when I try to compile them with the makefile, assuming this
is what I am supposed to do.
I'd appreciate any advice.

maybe it's just me, but I can't find said file...?
Hi,
Thought I'd share some info about a site I just read about
www.linuxfund.org. They apparently are able to hand out funds to (some
of the) projects that apply for it. Funds seems to be handed out with a
voting system. The grants are on the order of $1000 which isn't that bad
for hacking students :).
So, if anyone thinks they'd be helped by a grant for their projects, be
sure to check it out. I have no idea what the criteria are to be accepted.

Forget it guys, I'll do it by myself. I really don't care anymore if I
am the only person who ever uses it.
I just wanted some tools that did what I want the way I want it. Since I
can't run Rebirth on Linux I made a tool like it but not copying it. I
don't want to get into trouble with them. It doesn't violate any
copyright laws that I know of.
I'm not really looking for anything, but it would sure be nice to have 1
person out of the 50 a day who download a day send me an email saying
hello how are you. That is what drives me nuts. Software doesn't grow on
trees and I spent 6 hard months of intense work getting something like
this to come togethor.
Peace

http://plugin.org.uk/releases/0.4.0/
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

Hi.
I released ZynAddSubFX 1.2.1, a powerfull synthezier
for Linux and Windoze.
Get it from:
http://zynaddsubfx.sourceforge.net/
News:
- improved filter interpolation
- bugfix: wav header is written correctly
- bugfix: NRPN works correctly (eg:the
controller was 0x98 instead of 98), now you can
controll all effects parametrer realtime via MIDI
- bugfix: pitch bend works OK in windows
- added master fine detune (-64..63 cents)
- it is possible to swap effects or copy them
- started to port ZynAddSubFX to VST (not
functional, yet)
- the resonace can protect the fundamental freq.
against damping
Paul.

Dear Sir,
REQUEST ASSISTANCE/PARTNERSHIP .

After the sucessful transfer, 20% of the total sum will go to you for your assistance. 5% of the total sum will be set aside to compensate for any incidental expenses incured by both parties.
More details will be given in the course of correspondence.
Your confidentiality is highly required since I am still in active service .
