[linux-audio-dev] Some music made with Linux

by Pete Bessman

Hi all, Check out http://www.soundclick.com/bands/8/eastsidemilitiamusic.htm After getting Specimen to an acceptable state, I threw together this proper demo. It has no vocals since me and my larynx don't get along, but I encourage anyone who so desires to rectify that deficiency. I used Seq24 for MIDI sequencing, Specimen for sampling, and Ardour for recording. Except for the guitars, everything in this song was produced by Specimen+Seq24. Someone on this list asked me to keep a detailed journal of the process by which I created this (unfortunately I can't remember who). Well, as far as the Linux side of things goes, it's not very interesting. I used the aforementioned tools in a typical fashion. For general recording, any account I have to write would be duplication of effort. Instead, check out: http://www.tweakheadz.com/guide.htm Oh, and give the song a listen beyond the cheesy introduction. That part is meant to sound cheesy. If the rest of the song sounds cheesy, then I'm a failure, but have patience with the intro ;-) [pb]

[linux-audio-dev] wcnt-1.1001 release

by James W. Morris

Hello people, I've just released Wav Composer Not Toilet 1.1001 on sourceforge. (wcnt.sourceforge.net) I wondered if anyone could compile it on different distros etc, as I'm not overly confident it will. The reason being I'm not sure I've got autoconf etc set up correctly, as when I create a new project in Anjuta, it will not autogenerate it. I've had to import the project from the last release and modify the makefile.am's so it will compile the new source files. It compiles alright on my system anyway. Just a side note, for those who remember the wcnt filters thread. I changed the filters so they now have a feedback input. I've linked together 3 lowpass filters, the first gets feedback from the last, and the second and third feedback into themselves, one of which has a negative feedback level. Also there is a range_limit module before the feedback is fedback which clips the signal. The result sounds to me like a cross between resonance and echo/reverb. I was pleasantly surprised. This can be found in the examples within the tarball.

[linux-audio-dev] [ANN] TAP-plugins 0.4.0

by Tom Szilagyi

Hi all, TAP-plugins 0.4.0 is just released. Check it out at: http://tap-plugins.sf.net New plugins: * TAP Pitch Shifter Gives you the opportunity to change the pitch of individual tracks or full mixes, in the range of plus/minus one octave. Audio length (tempo) is not affected by this plugin, since audio is completely resampled. * TAP Rotary Speaker Simulates the sound of rotating speakers. Two pairs of rotating speakers are simulated, each pair fixed on a vertical axis, with their horns spreading the sound in opposite directions. * TAP Vibrato Modulates the pitch of its input signal with a low-frequency sinusoidal signal. It is useful for guitar and synth tracks, and it can also come handy if a strange effect is needed. Bugfixes: * Fixed crashing bug in TAP Reverberator (this bug appeared with hosts that call activate() before connect_port()). * Fixed lock-up bug in TAP DeEsser (the bug appeared when an input sample had +/- INF value). * Various smaller bugfixes (almost all plugins locked up when control input values of +/- INF were appiled). A recommended upgrade ;-) Enjoy, Tom

[linux-audio-dev] have to restart jack between ecasound sessions

by Eric Dantan Rzewnicki

I'm starting jack via jackstart like this: jackstart -v -R -d alsa -d ice1712 -r 44100 -p 64 -n 2 I can run ecasound in many ways (different chain settups, via ecaplay, wav or ogg input, etc.) one time only. If I try to run another ecasound session without restarting jack the second ecasound exits like this: audiobox:~$ ecaplay /mnt/audio/in_progress/guitar_mix/s2004-0217-2242.ogg *********************************************************************** * Message from libecasoundc: * * 'ECASOUND' environment variable not set. Using the default value * value 'ECASOUND=ecasound'. *********************************************************************** (ecaplay) Playing file '/mnt/audio/in_progress/guitar_mix/s2004-0217-2242.ogg'. exiting... It doesn't return ... just hangs like that until I ctrl-c it. If I strace the ecaplay it's waiting for ecasound: audiobox:~# strace -p 450 Process 450 attached - interrupt to quit waitpid(451, <unfinished ...> Process 450 detached which is stuck in a futex(): audiobox:~# strace -p 451 Process 451 attached - interrupt to quit futex(0x413e6bf8, FUTEX_WAIT, 453, NULL Once I kill the ecaplay w/ctrl-c the "ecasound -c -D" remains until I use kill -9 on it. Anything else I can do to help debug this? System details below.

[linux-audio-dev] MIDI interface latency

by jrobbins＠nymu.net

Anybody know what's the minimum latency that can be achieved passing MIDI notes from one computer to another? I'm wondering if it's possible in theory to set up an audio generation cluster to be used as a realtime instrument. Basically, have a network aware synthesis app running on all machines, administer the setup/modification of the signal flow architecture from one master machine in non-rt over sockets, and then pass notes to the appropriate machines using midi interfaces. Naturally this depends on a signal path separable into big chunks. I have a hunch that midi over ip has latency too high and unpredictable for this. -jacob

[linux-audio-dev] caps 0.1.0

by Tim Goetze

pleased to announce the initial release of the caps audio plugin suite under the GNU public license. quoting http://quitte.de/dsp/caps.html : caps, the C* Audio Plugin Suite, is a collection of refined LADSPA units including instrument amplifier emulation, stomp-box classics, versatile 'virtual analog' oscillators, fractal oscillation, reverb, equalization and others. some of caps is an improvement over previous efforts (the rewritten amplifier emulation plugins for example do 8x oversampling using polyphase filters, for much cleaner sound) but most of the plugins are ex nihilo creations. for those with an interest in DSP effects but no time or opportunity to run the plugins, the data sheets provided through the above document may be interesting. enjoy, tim
