filter?

by Josh Lawrence

I'm looking for a filter for running loops through. Something where I can do run-of-the-mill filter sweeps on audio loops. Is there such an animal? Jack functionality would be required. Additional functionality is always a huge plus, but basic filter sweeps are the main thing here. -- Josh Lawrence http://www.hardbop200.com

Re: [LAU] A Library of a Turkish percussion instrument for GNU/Linux audio users community

by Juhana Sadeharju

>From: Florian Schmidt <mista.tapas(a)gmx.net> >> >> http://www.ardaeden.net/asma_davul/ > >Nice playing on the demo, too. And you like overcompressed, overreverberated >sounds, too :) Are the sounds prereverberated or just the demo? (Cannot listen them.) I would like to see more turkish, arabic, and persian instrument sound libraries which are free. And a guide on how to sample instruments. Percussions may be easy but flutes like Mey (Duduk) looks more difficult. I have already decided that it would be better to have both the original recordings and the looped (read: ruined) samples. I have used granular methods in succesfully stretching the sounds, and some claim phase vocoder does good job too. I also would like to see physically modelled instruments for the instruments such as Mey. I remember acoustics.hut.fi have modelled Tanbur but I have not found source codes. Juhana

AZR-3, recent bugfixes

by Lars Luthman

I normally don't announce 1.0.* releases on the lists to keep the noise down, but I thought that I'd mention some of the fixes that have gone into my JACK port of AZR-3 since 1.0.0 in case someone has had any problems building it and don't know that there are newer versions available. There are no new features so if your current copy works for you there is no reason to upgrade. Changelog since 1.0.0: Version 1.0.3 (2008-05-15): * Fixed some #include bugs that were only exposed in GCC 4.3 Version 1.0.2 (2008-01-07): * Added compatibility code for new JACK API (>= 0.107) Version 1.0.1 (2007-12-26): * Fixed crashing bug reported by Sebastian Tschöpel * Treat Note On with velocity 0 as Note Off (not sure if that is allowed in JACK but it doesn't hurt) * Fixed graphics bug that broke the background pixmaps for the text box and all the knobs and drawbars You can always get the latest release at http://ll-plugins.nongnu.org/azr3 and the latest development code from the Git repository: git clone git://git.sv.gnu.org/ll-plugins/azr3-jack.git and to update it with recent changes: git pull If you have been tracking the development using CVS until now you probably want to switch to Git as the CVS repository will no longer be updated. --ll

[ANN] jack-smf-utils 1.0

by Edward Tomasz Napierala

Version 1.0 of jack-smf-utils can be downloaded from: http://pin.if.uz.zgora.pl/~trasz/jack-smf-utils/jack-smf-utils-1.0.tar.gz Jack-smf-utils is a set of two command line utilities - jack-smf-player and jack-smf-recorder - whose purpose is to play and record MIDI streams from/to Standard Midi Files (i.e. the files with .mid extension) using JACK MIDI. There is also smfsh, "SMF shell", that is an interactive, command line driven SMF files manipulation tool which started its life as a debugging aid. And finally libsmf, C library for loading, writing and manipulating the contents of SMF files. http://pin.if.uz.zgora.pl/~trasz/jack-smf-utils/ API documentation for libsmf is here: http://pin.if.uz.zgora.pl/~trasz/jack-smf-utils/doc/ There is no separate package for libsmf yet; if you need it - let me know. -- If you cut off my head, what would I say?

Gutsy problems with Audacity opening sound device

by Christian Einfeldt

hi I and a friend are both having problems using Audacity to edit music files. In my case, I am trying to edit an .ogg vorbis file, and in his case, he is trying to edit a file that he recorded with Audacity. He is a 69 year-old man, and I am trying to assist him over the phone, so it is kind of hard to get complete details from him, but, fortunately, I am having the same problem on my Gutsy install with Audacity 1.3.3-beta. Here is the exact error message that we are getting: Error while opening sound device. Please check the output device settings and the project sample rate. I have googled and found that there are a lot of problems with Gutsy getting this error message. The suggested solutions fall into two camps, neither of which has worked for me. The first camp is grepping for the jackd process and killing it in the shell; the second involves making sure that you have sound privileges (we do) and that you are using the correct sound device (not sure how to tell about that). The helpful links on these topics are below: http://ubuntuforums.org/showthread.php?t=710881 https://answers.launchpad.net/ubuntu/+question/26900 Grepping, I get no responses to jackd at all: cje@rb:~$ ps -e|grep jackd cje@rb:~$ ps -A | grep jackd cje@rb:~$ ps -A | grep jack* cje@rb:~$ ps -A | grep jack cje@rb:~$ ps -e > jackd_test.txt cje@rb:~$ As you can see, I directed the grep output to a txt file, and I looked at the txt file, and sure enough, no jackd. So that solution won't seem to work. With regard to the potential solution of choosing the "correct" sound device, as suggested by the second link above, I went to Edit > preferences > Audio I/O and found that these are my choices: not sure which are right, and I'm not sure I want to go messing around with settings until I know what is up: ALSA: HDA ATI SB: ALC883 Digital (hw:0,1) ALSA: default ALSA: iec958 ALSA: spdif ALSA: dmix Thanks in advance for any help! -- Christian Einfeldt, Producer, The Digital Tipping Point

24bit/96kHz soundcard

by Massimo Corinaldesi

Which one compatible with linux (mandriva 2008.0) ? I tried with Chaintech AV710: it works, but no luck to setup the 24bit/96kHz to send flac music to the spdif to and external dac. Always less bits and/or kHz. The envy24control software supports ice1712 processor while my cards exhibits ice1724 ! Thanks. Massimo -- Massimo I0MCF http://www.ziomassimo.it

Too loud (aka "Red" zone) - how much dB

by Peteris Krisjanis

Hi! I am helping to code small sound editor and we will have waveforms. However, we need to know what constitutes too loud, aka after how much dB we can do a cut off in waveform and putting red stage in mixer? Any hints how everyone is dealing with this? Already thanks for any clues, Peter.

Roland-Edirol Sound Canvas and other synths

by Roger Wakeman

I was browsing through the ALSA supported devices and noticed all of these Roland-Edirol synth units that are supported. Does anyone have any experience with these? I'm having trouble figuring out exactly how they function. Do they receive MIDI data and then send audio streams to the computer through USB? Do they receive MIDI data from the computer or from another external device? Are they well supported? I'd like to include them in my compatible hardware list but wish to learn more first.
