xfmr-plugins-0.0.1

by John Rigg

xfmr-plugins-0.0.1 has been released. At present it contains one LADSPA plugin, an anti-aliased transformer distortion emulator intended to be used on the master bus when mixing in a DAW such as Ardour. I made it for my own use, in order to get closer to the sound of an analogue mix without the extra round trip through the DA-AD converters. Hopefully others may find it useful. License is GPL v2. More details and download link here: http://www.jrigg.co.uk/linuxaudio/xfmr-plugins.html John

Lisalo -Linux Sampler Loader- 1.2 Release. Now with sidekick tool to load directories with wavs and oggs

by Nils

Lisalo - Linux Sampler Loader - is a command line program that loads entire directories of sample files, a single .sfz file or takes instructions from a meta .lsl file with relative paths to samples. Now you can quickly and easily load sampled instruments without even starting a GUI. This is release 1.2, grab it here, no installation required (but you can symlink it to /usr/bin if you want) git clone git://github.com/nilsgey/Lisalo.git [New Features] lsl mode (see example.lsl) -Choose an instrument index when loading gig or sf2 samples -Load a directory with waves and oggs as one instrument. -Choose a name for your JACK port commandline mode (see -h or cat README) -option to specify a name for your JACK port. -directly load a single sfz file instead of a whole directory or a meta lsl file (auto detection by file extension) -this sfz file can be a temp file created by Lisalos sidekick: [New Tool - Sfz Generator] Creates temporary sfz files. Point to a directory of wave or ogg files and you'll get the filename of an .sfz file in /tmp as return value. In case you want to use this with Lisalo use the following syntax: lisalo "$(lisalosfzgenerator.py /path/to/wavedir)" This has several optional options such as: Start mapping from a key number (default 60 - middle c), only map the white keys, load sample dir recursively (don't point at your /home/samples or at an Ardour project dir!) [Contact] https://github.com/nilsgey/Lisalo info(a)laborejo.org irc.freenode.org #laborejo [Dependencies] Python3 (Developed and tested under 3.2.2) Linuxsampler (no GUI required) Feedback and idle chatting are welcome!

It was the -lm option. With that added to the LD line in the makefile it could find cos, which was the undefined symbol stopping demolition. Other undefined symbols like malloc, calloc and free didn't bother it (these could be defined with the -l:libc.so option but it wasn't necessary). Thanks, John

LADSPA plugin undefined symbols

by John Rigg

(Hope this is the right place to ask - apologies if not). I'm trying to test my new LADSPA plugin with demolition but the latter fails due to undefined symbols. Running objdump -t on the .so lists several of the standard C functions used in the code as undefined symbols. I've tried installing libc6-dbg and adding -g to the CFLAGS in the makefile (which is a modified version of the one in ladspa_sdk) but it makes no difference. System is Debian testing amd64 (pre-multi-arch snapshot from Jan 2012). I thought it might be due to a mismatch in the build tools, so I tried building the plugin on Debian Lenny (5.0.3). The same thing happens there. I've tried running demolition on a couple of the Debian packaged swh-plugins and it runs without a problem, but any plugin I compile from source (not just mine) gives the same type of error. All of the undefined symbols are standard libc functions like malloc, calloc, free, cos etc. The plugin works perfectly in Ardour2 on both systems. Anyone have any ideas how to fix this? John

[ANN] TAP-plugins 0.7.2

by Tom Szilagyi

Hi all, This is a small bugfix release of the TAP-plugins LADSPA plugin collection. The only plugin affected is the Scaling Limiter. The problem was that with some kinds of audio (esp. low freq. sine waves) the plugin produced sharp peaks / level jumps in the output. Thanks to Taku Yamamoto for providing me with an excellent patch. Downloads etc: http://tap-plugins.sf.net Enjoy! Tom

New release of avw.lv2 and youtube tutorial

by Aurélien Leblond

Hi everyone, I released a new version of the avw.lv2 plugins today - version 0.0.8. You can grab it here: https://sourceforge.net/projects/avwlv2/ or on GitHub here: https://github.com/blablack/avw.lv2 This new version doesn't include much changes: - David Robillard updated some of the port to the new Voltage Control format. - The code was cleaned a bit. I was able to create very basic synths, so it seems usable :) You'll need to grab the latest version of Ingen though to avoid a few crashed (at least SVN 4506) I as well started to create Youtube tutorial for Ingen. The first one is available here: http://youtu.be/9nC7giX1ToQ As it is the first one, do not hesitate to provide me with feedback! Thanks in advance, Aurélien P.S: Thanks to David for the fixes in Ingen and the patch for AVW.
