Hello again! I'm sorry, but my earlier experiments don't seem worth the effort. Now I thought, this has all been done and perhaps someone can help me. I need a tree stucture in C, based on struct, where each node has a list of subnodes. like this: (root(e1(e11,e12,e13(e131,e132,e133,e134,e135)),e2) If you get what I mean. Does anyone know of such a structure almost made ready for use? I'm sure I heard the official name for this in my lectures, but alas it's long ago. Yes, I did consider doing this in c++, but then readline will get me down on my knees again and will have my crying in frustration and defeat, as it did last time. :-( Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

[LAD] [ot] how to produce ^m ?

by Julien Claassen

Hi! Does anyone know which character exactly ^m is and how I can reproduce it as a character in my program code. Unfortunitely I get it from the outside and have to deal with it.

[LAD] [ot] programming typedefs...

by Julien Claassen

Sorry folks! But I'mtoo stupid. I have a struct, which contains a pointer to itself as an element. How to write this. I once knew, but now I fail. It's a shame! :-( Kindest regards Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

[LAD] RME madiface

by D. Sen

Hello, I have been trying to use the hdspm driver with a recently purchased RME Madiface device. The functionality that I require is to play various files through various channels under program (script) control. I am happy to report that it *almost* works - in that I can use my simple userspace programs to play files. However, there are subtle problems - in that the external MADI A-to-D (an Euphonix 703) does not seem to lock into the sampling rate (something that works under windows). Its very close to achieving full functionality (for my needs) - but just that tiny bit away from being fully useable. Any ideas? Havent had much luck contacting RME and Winfried Ritsch (who wrote/maintains the code). Information on the the hardware and/or windows code would help to figure out how to modify the driver (which was originally written for the rme 9652/aes32 devices). Regards, D. Sen

[LAD] [ANN] Vamp plugin SDK v1.3 now available

by Chris Cannam

Version 1.3 of the Vamp plugin SDK is now available. http://www.vamp-plugins.org/ Vamp is a plugin API for audio analysis and feature extraction plugins written in C or C++. Its SDK features an easy-to-use set of C++ classes for plugin and host developers, a reference host implementation, example plugins, and documentation. It is supported across Linux, OS/X and Windows. Version 1.3 is a maintenance release, with several bugfixes (almost all of which only affect hosts, not plugins) and no new features. Changes since 1.2: * PluginBufferingAdapter has several important fixes to bugs that could cause incorrect timings or output descriptors to be returned * Conversion between real-time and frames has been improved to avoid rounding error in round-trip calculations * Plugin lookup no longer relies on non-portable DT_REG * The SDK now compiles with gcc 4.3 (knowing my luck it probably won't, but it's supposed to) Plugins and hosts remain binary compatible with those built using the 1.0 version of the SDK.

Rubber Band is an audio time-stretching and pitch-shifting library and utility designed for musical applications. http://www.breakfastquay.com/rubberband/ It includes a library that supports a sample-accurate multithreaded offline mode and a real-time lock-free streaming mode; a command-line utility program; and a LADSPA pitch-shifter plugin. Version 1.2 is faster in most situations, better sounding in many, and less potentially subject to patent claims than version 1.0.1 was. Rubber Band is Free Software under the GNU GPL. Chris

[LAD] 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.

[LAD] [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.

[LAD] 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.
