[linux-audio-dev] [ANN] Snd-ls V0.9.5.4 and Das_Watchdog V0.2.1

by Kjetil S. Matheussen

Download from http://ccrma.stanford.edu/~kjetil/src/ Snd-ls v0.9.5.4 ================ Contains -------- Snd v7.15 from 17.8.2005 About ----- Snd-ls is a distribution of the sound editor 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. Changes 0.9.5.3 -> 0.9.5.4 -------------------------- -Changed default resampling quality to SRC_SINC_BEST_QUALITY -Added workaround for shift-handling across various keyboard settings. (shortcuts for zoom in and undo works with american keyboards now.) -Added check for Guile 1.8. Snd-ls crashes with guile 1.8. (all versions I have tried of 1.7 seems to work though...) -Use JackPortIsPhysical instead of "alsa_pcm" when finding jack ports. -Updated the rt stuff to latest versions. *************************************** *************************************** Das_Watchdog V0.2.1 =================== About ----- Das_Watchdog is a general watchdog for the linux operating system that should be runned in the background at all times to ensure a realtime process won't hang the machine. Changes 0.2.0->0.2.1 -------------------- *Cleaned up source a bit. *Properly find number of timer processes. *Added shortcuts for optargs.

[linux-audio-dev] python and jack, performance report

by Leonard "paniq" Ritter

-- oops, the first one was sent as a reply, here's the whole thing as a new thread. frustrated by the poor implementation of the jack bindings for python (pyjack), i wrote my own in native python using ctypes. the first test client mixed a 440hz sine wave using native python lists, and the cpu usage was about ~11%. i reimplemented the sine generator with numerics, and got it down to ~2%. i believe that considering the overhead of the python implementation, that result isn't too bad, and maybe allows for more than just prototyping. i attached the jack wrapper with the test client contained for those who are interested. its not entirely wrapped and lacks some functionality. -- -- leonard "paniq" ritter -- http://www.mjoo.org -- http://www.paniq.org

[linux-audio-dev] Linux Audio Conference 2006: Register now!

by Frank Neumann

Hi all, this mail is just to inform you that registration for the 4th International Linux Audio Conference (or "LAC2006" for short), APril 27th-30th, in Karlsruhe, Germany, is possible as of now by visiting our web page at http://lac.zkm.de and clicking on the link "Registration" on the left. Like last year (and the years before), registration is free and is only necessary because we need to prepare nametags, make estimations about room sizes/required chairs and want to learn a bit about our audience. That's all, honestly! :-). Information given there will NOT be used for any kind of selling, spamming or otherwise abusing. Also, the preliminary conference program has been published a few weeks ago, available through the same link give above. Thanks for registering in case you plan to come! Greetings, Frank Neumann Goetz Dipper LAC2006 organization team

Re: [linux-audio-dev] Best opensource license to use?

by Chris Cannam

> i intend to release an application, which allows to > use VST(i)s running on an XP machine from > a linux jack client, hooked up over ethernet. If all the code is your own, consider the approach we used in dssi-vst, which is to use the GPL plus an exception to allow for the unavailability of VSTSDK sources. It won't be GPL-compatible or "Debian" free, but nothing will be if not all the source is available, and I think it best expresses the intention -- if your preference would naturally be for the GPL, that is. Meanwhile, write and remind Steinberg that their license could be more helpful to developers of Windows and Linux plugins and hosts. It won't be news and there's no real reason they should care, but it's worth a nudge that these things matter to people, including those who would like to promote, recommend and use their standard. As it happens I'm also shortly about to release a Windows plugin host that is not at all in competition with Steinberg products, but that can't host VSTs for licensing reasons and will use DSSI plugins instead. Hosting audio plugins is not a major part of this program so the difference isn't going to be all that significant to me or anyone else, but it's an interesting situation. Chris

[linux-audio-dev] What is currently the best USB audio interface for Linux?

by ico

Hi all, I am in the process of considering a portable USB audio interface. Having checked the alsa matrix, I am a bit at a loss what may be the best option. Things I am looking for are as follows (they are listed in no particular order): 1) USB interface 2) Preferrably USB 2.0 capable 3) Audio and MIDI capability 4) High fidelity (higher the better) 5) More inputs/outputs, the better 6) Preferrably has some preamp inputs 7) Obviously must be supported in Linux/Alsa 8) Price not an issue Any ideas? Best wishes, Ico

[linux-audio-dev] LADSPA processing: ams, om, ... Anything else?

by Andrew Gaydenko

Are there alternatives for 'ams' and 'om'? My problems are: - 'ams' has not text fields to type-in controls values with needed precision, sliders are not sufficient, - 'om' engine has too many crashes (I see, it is normal, as the app is under development). Anything else?

[linux-audio-dev] [ANN] netjack-0.9 with alsa I/O (also can be used to bind jackd to 2 soundcards)

by torbenh＠gmx.de

ok... netjack-0.9 is here. this is basically netjack-0.9rc4 with the transport offset of one period fixed. additionally i have added 2 jack clients which open unrelated soundcards. these are fixed reimplementations of the old alsa_client. fully configurable, and better than the alsa_client. it does even work with usb soundcards. using a second soundcard for monitoring purposes is now possible. the only current limitation to this is 16bit. but this will be changed soon... -- torben Hohn http://galan.sourceforge.net -- The graphical Audio language

New opcodes: New track processing opcodes for PVS system: trscale - streaming partial track frequency scaling trshift - streaming partial track frequency shifting trsplit - takes an input containg a TRACKS pv streaming signal and splits it into two signals according to a k-rate frequency 'split point'. trmix - takes two inputs containg TRACKS pv streaming signals and mixes them into a single TRACKS stream trfilter - filters a TRACKS pv streaming signal using an amplitude response curve stored in a function table trcross - streaming partial track cross-synthesis trhighest - extracts the highest-frequency track from a streaming track input signal trlowest - extracts the lowest-frequency track from a streaming track input signal binit - PVS tracks to amplitude+frequency conversion barmodel - creates a tone similar to a struck metal bar max - produces a signal that is the maximum of any number of input signals min - produces a signal that is the minimum of any number of input signals maxabs - produces a signal that is the maximum of the absolute values of any number of input signals minabs - produces a signal that is the minimum of the absolute values of any number of input signals maxaccum - accumulates the maximum value of audio signals minaccum - accumulates the minimum value of audio signals maxabsaccum - accumulates the maximum of the absolute values of audio signals minabsaccum - accumulates the minimum of the absolute values of audio signals Changes: Several opcodes and opcode groups have been moved out of the Csound library and stdopcod library into separate plugins (vbap, babo, grain4, hrtferX, PhisEm opcodes). Improvements in JACK plugin to allow lower latency and remove some restrictions on buffer sizes. Bug fixes: Bug fixes in FLsetVal and FLsetVal_i; allow buttons and button banks in FLsetVal; fixed handle output of FLbutBank (not sure if this is safe); implemented cursor size parameter for FLknob. Fixed bugs in i-rate ZAK opcodes. Fixed hang on very short note before end of score or section. Added hacks to fix the problem of the else branch of an if/then/else always being executed at i-time. Fixed crash on 'then' or 'goto' in variable names in conditional expression for if/elseif. Fixed crashes on missing whitespace between if/elseif and '(' and on extra ')' in expressions. and of course a number of minor bug fixes all over Changes: 2006-03-16 Istvan Varga <ivarga(a)csounds.com> * Opcodes/sftype.h: check for MacOS 9 or PowerPC, and define WORDS_BIGENDIAN on those platforms. 2006-03-13 Anthony Kozar <anthonykozar(a)sbcglobal.net> * Top/main.c: Made TYP_AIFF the default for MacOS 9. * Engine/entry1.c: Removed duplicate OENTRYs. 2006-03-12 jpff <jpff(a)codemist.co.uk> * Opcodes/bilbar.c (bar_run): Corrected boundary condition 2006-03-11 Istvan Varga <ivarga(a)csounds.com> * Engine/express.c: fixes in extending tokenstring buffer 2006-03-10 Anthony Kozar <anthonykozar(a)sbcglobal.net> * Opcodes/minmax.c: * SConstruct: Added new 'minmax' plugin library with opcodes for finding minimum and maximum values among several signals. 2006-03-10 Michael Gogins <gogins(a)pipeline.com> * CSD style command lines in CsoundVST are now translated to orc/sco style before performance in order to save having to edit the command line after loading some CSD files. 2006-03-08 Istvan Varga <ivarga(a)csounds.com> * Made it possible to load opcode plugins only when the opcode is actually used. 2006-03-07 jpff <jpff(a)codemist.co.uk> * Engine/otran.c: Removed DTYPE and lclnxtdcnt as not used 2006-02-25 Michael Gogins <gogins(a)pipeline.com> * Updated SConstruct, custom.py, and Windows installer to build and install PortMidi. 2006-02-24 Istvan Varga <ivarga(a)csounds.com> * InOut/rtjack.c: Use thread locks instead of calling usleep() in a loop to implement blocking I/O; the -+jack_sleep_time option is now deprecated and ignored. Allow non power of two values for -B. Setting -b to the same value as the JACK buffer size is no longer required. * Engine/insert.c: * Engine/musmon.c: Alternate fix to problems on very short (less than 1/2 control period) notes; the previous fix introduced a new bug that resulted in early termination of the score in some cases. * H/version.h: * installer/misc/csound.spec.in: Updated version number from 5.00.1 to 5.01.0 to reflect the addition of new opcodes. 2006-02-24 Victor Lazzarini <Victor.Lazzarini(a)nuim.ie> * Opcodes/psynth.c new track processing opcodes (also added manual pages): trscale, trshift, trsplit, trmix, trfilter, trcross, trhighest, trlowest, binit. 2006-02-15 Istvan Varga <ivarga(a)csounds.com> * InOut/widgets.h: moved file from H/ * InOut/widgets.cpp: bug fixes in FLsetVal and FLsetVal_i allow buttons and button banks in FLsetVal fixed handle output of FLbutBank (not sure if this is safe) implemented cursor size parameter for FLknob 2006-02-13 Istvan Varga <ivarga(a)csounds.com> * OOps/ugrw1.c: fixed bugs in i-rate ZAK opcodes 2006-02-09 Istvan Varga <ivarga(a)csounds.com> * Engine/rdorch.c: splitline(): made checking for invalid characters stricter fixed labels before else/endif allow bitwise NOT operator in UTF-8 format 2006-02-06 Istvan Varga <ivarga(a)csounds.com> * Engine/entry1.c: cogoto requires an i-rate conditional * Engine/musmon.c: fixed hang on very short note before end of score or section * Engine/rdorch.c: added hacks to fix the problem of the else branch of an if/then/else always being executed at i-time. Fixed crash on 'then' or 'goto' in variable names in conditional expression for if/elseif (still does not work if there are no parentheses around the conditional expression). 2006-02-03 Istvan Varga <ivarga(a)csounds.com> * Engine/rdorch.c: fixed crash on extra ) in expressions * Engine/rdorch.c: fixed crash on missing whitespace between if/elseif and ( this needs more testing
