Regarding the linux-audio lists announcing policy

by Kjetil S. Matheussen

I wonder if we could change the post-to-all-three-lists policy? I don't like to spam three mailing lists for everytime I announce a program, and it doesn't seem like everyone knows that we are supposed to post to all lists either.

[ANN] jack_capture V0.9.19, Snd-ls V0.9.8.17 and Rollendurcmesserzeitsammler V0.0.4

by Kjetil S. Matheussen

Download from: http://old.notam02.no/arkiv/src/?M=D jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file. (But it can do a number of other operations as well...) Changes 0.9.17 -> 0.9.19: *Do not accept filename starting with "-" when filename is last argument. *Added the "--filename"/"-fn" option to set filename not as the last argument. Can also contain "-" as first character. *Fixed colors a bit and removed a superfluous linebreak. *Fixed segfault for missing values in commandline. *Manually clear allocated memory instead of using calloc. *Removed buffer-info line when recording to stdout. *Removed printing of "continue recording" when writing the last overruns. *Niceify the disk writing thread to -20 when more than half the buffer is used. *Continously show buffer usage, total number of overruns and whether the disk thread has high priority, in the console. Turn off by using the -hdu option. *Added option -dc to disable console update. (same as "-dm -hdu") *Fancier colors. *Removed "hepp". *Made dB meter the default and replaced the -dB option with the -lm option. *Made the console meter wider to fit the info line at the bottom. Snd-ls ====== Snd-ls is a distribution of Bill Schottstaedt's sound editor SND. (http://ccrma.stanford.edu/software/snd/) Its target is people that don't know scheme very well, and don't want to spend too much time configuring Snd. It can also serve as a quick introduction to Snd and how it can be set up. Snd-ls also serves as base code for the San-Dysth softsynth (http://www.notam02.no/~kjetism/sandysth/) and the Snd-rt music programming language (http://www.notam02.no/arkiv/doc/snd-rt) Changes 0.9.8.16 -> 0.9.8.17: *(read-enable 'positions) has been wrongfully turned off for some time. Bactrace should work again now. (This only affects people using snd-ls for programming.) Rollendurchmesserzeitsammler ============================ The Audio Rollendurchmesserzeitsammler is a conservative garbage collector providing general ways to efficiently allocate and use memory inside a realtime audio thread without having to manually free it later. Changes 0.0.1 -> 0.0.4 * Added support for iterior pointers. (Pointers which points inside middle of allocated memory). Turned out Stalin depended on this, plus that c compiler are free to store pointers in registers and stack however they want, so it's better to be safe. * Fixed header. * Made it packagable. Write make and make install to install library file and header files. * Added the function tar_get_dynamic_roots_for(char *pointer,char **start,char **end). This function requires the source for HBGC: http://www.hpl.hp.com/personal/Hans_Boehm/gc/ * Note that there are ways to increase the execution speed significantly, I just haven't had the time yet, so this update doesn't contain all the changes I wished for.

LinuxSampler questions

by Julien Claassen

Hello! Please Christian or someone else, can you help me. I just reread the LinuxSampler features page and seems to be some way of marking points as implemented, not done or partly implemented. But I can really find those markings. Can someone give me a list of clearly marked features (clearly as in text not colours or other visually markings). In particular I'm interested in the following: 1. Does LS support gigaStudio3? 2. Articluations (.art-files) 3. Convolution reverbs And another not completely related question: Is there a telnet equivalnet that supports a bit more line-editing and probably globbing. If I say telnet I mean the program "telnet". It's just annoying when misstyping not being able to correct the typos and when entering long filenames not being able to complete them.

LADSPA Vocoder plugin

by Gordon JC Pearce

For a while I've been using the sirlabs.de vocoder plugin: http://www.sirlab.de/linux/descr_vocoder.html But it has some problems, notably expecting two inputs but only offering one output. There was a patch on linuxrockstar which gave it two outputs, but something seemed a bit lacking, still. An evening of hacking and here we have it: http://www.gjcp.net/~gordonjcp/vocoder.tar.bz2 It's hard-set to eight bands, all with the same level. There's a bandspread control to alter the frequency spacing of the partials, and a width control to vary the stereo effect where odd bands go to the left output and even bands go to the right output. Give it a go and let me know how you get on. Gordon

[ANN] jack_capture V0.9.17

by Kjetil S. Matheussen

jack_capture ============ jack_capture is a program for recording soundfiles with jack. It's default operation is to capture whatever sound is going out to your speakers into a file, but it can do a number of other operations as well. Normal URL: http://www.notam02.no/arkiv/src/?M=D Note that the above link doesn't seem to currently work because of something which seems to be www upgrade at Notam. But this link does seem to work for now: http://old.notam02.no/arkiv/src/?M=D 0.9.10 -> 0.9.17: ----------------- *Made sure the process thread won't continue sending data when jack_capture is told to quit. This led to a race conditions when recording too many channels at once (which was 256 channels on my machine). *Added the jack_capture_gui script, based on code by Svend-Erik Kjær Madsen's. *Replaced sh by bash to make it work in ubuntu. *Fixed exact port name match and gen_setformat. Thanks to Gabriel J.L. Beckers for reporting the bugs. *Increased the time the console meter is displayed in red from 50ms to 2000ms. (when the recorded jack value is equal to or higher than 1.0.) *Added the -dBr argument to specify reference level when using the console dB meter. *Added the -mr argument to specify reference level when using the meterbridge meter. *Added peak indicators to the console meter. Code to do so taken from meterbridge by Steve Harris. *Updated --help and README with the new options. *Added option "-mt" to change meterbridge type. Current valid options are vu (default), ppm, dpm, jf or sco. It's not necesarry to specify "-mb" if using "-mt". *Added option "-dB" to get a dB meter for the console meter. *Added examples how to record ogg and mp3 files using the -ws option. *Decreased default buffersize from 60 to 20 seconds. (I even had trouble provocing underruns using a minimal 0.05 seconds long buffer, so 60 seconds was obviously overkill) *Fixed message and error printing to stderr when vu meter is running.

Re: [LAD] Host 128.173.232.121 is unreachable via http or smtp ports

by Ivica Ico Bukvic

Thanks Ron for the info, we are already aware of this issue and are working on it as fast as we can. As unlikely as it sounds, it appears we've had a major thunderstorm that has knocked out several buildings on campus, including the building hosting our server. Unfortunately, I've been out of the country and unaware of this occurrence until it was brought to my attention yesterday. Let me say that this is a very unusual and very much unexpected occurrence. That being said, based on this unfortunate development we will look to invest into better UPS asap to minimize any potential downtime in the future. As of 4:58PM the server should be back up and running.

libsndfile-1.0.18pre7 patch

by Fons Adriaensen

Libsndfile-1.0.18pre7 has some regression w.r.t. earlier prereleases. - When writing a WAVEX it always writes the Ambisonic GUID, and sets the channel mask to 0. Since it can also read this and you can't get the channel mask value, this will go unnoticed until you use some other lib to read the file. - When reading it always tells you the file is not Ambisionic. The attached patch will fix this AFAICS. Ciao, -- FA Laboratorio di Acustica ed Elettroacustica Parma, Italia Wie der Mond heute Nacht aussieht ! Ist es nicht ein seltsames Bild ?

hosts for LV2 synths

by Pau Arumí

Hi all, I want to try LV2 synths and try developing new ones. The plugins API and compilation seems all pretty clear, but I don't know what are the existing host options. I was about to try zynjacku with jack-keyboard. Is it compatible with any LV2 synth? Are there sequencers connectable to zynjacku? (that is: jack-midi enabled?) http://home.gna.org/zynjacku/ http://pin.if.uz.zgora.pl/~trasz/jack-keyboard/ Thanks! Pau

Bit OT: cleaning code for gcc4

by Julien Claassen

Hello everyone! I'm just working on some older code, trying to clean it up for GCC4.2.3. I get a lot of warnings like this: CuSE.cxx:321: warning: deprecated conversion from string constant to 'char*' Not this line but still same kind of error: char* choices[] = {" [ ] ", " [*] "}; The line 321 WARNING was using the defined choices and another char* array used in a newCDKSelection call. How can I clean this up?
