[linux-audio-dev] Why alsamixer starts with all the volumes settings in 0?

by Lisandro Damián Nicanor Pérez Meyer

Hi everyone! I was just wondering why alsamixer starts with all volume settings in cero. I guess there should be an aswer to this, so I decided to ask you. What I didn't know was if to ask here or to lau's list, so I decided to go directly to the designers :-) Also, it is possible to, at least, lstart with the main volume and pcm/wav just a little bit raised? I think this would help when configuring alsa, specially for newbies. Thanks in advanced! Cheers, Damian.- Outside of a dog, a book is man's best friend.

[linux-audio-dev] [ANN] Snd-ls V0.9.4.3, Mammut V0.20, Ceres V0.43 and Snd RT-extension documentation updates.

by Kjetil Svalastog Matheussen

***************************************************************************** 1. Snd-ls v0.9.4.3 --------------- Released 30.6.2005 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 from 0.9.3.0 to 0.9.4.3 -------------------------------- -Upgraded various rt-stuff. -Upgraded various rt-stuff++ -Removed jack_set_server_dir guile-binding from rt-engine.scm, because its removed from the newer versions of jack. -Updated SND to v7.14 from 19.6.2005. Many important changes. http://www.notam02.no/arkiv/src/snd/ ***************************************************************************** 2. Mammut V0.20 ------------ Mammut will FFT your sound in one single gigantic analysis (no windows). These spectral data, where the development in time is incorporated in mysterious ways, may then be transformed by different algorithms prior to resynthesis. An interesting aspect of Mammut is its completely non-intuitive sound transformation approach. Changes 0.18 -> 0.20 -------------------- -Fixed a bug in the Makefile caused by a fix in the previous release. -Fixed some bugs in the Makefile. http://www.notam02.no/arkiv/src/ ***************************************************************************** 3. Ceres V0.43 ----------- Ceres is an advanced program for displaying sonograms and for sound effects in the frequency domain. And more. Changes 0.42 -> 0.43 -------------------- -Fixed some bugs in the Makefile http://www.notam02.no/arkiv/src/ ***************************************************************************** 4. Snd RT-extension documentation ------------------------------- The realtime extension for SND makes it possible to do signal processing in realtime using guile and a special scheme-like compiled language. It has many features, as jack-support, CLM, a realtime scheduler, a compiler, busses, dynamic patching, shared variables, ladspa and more. It can also be made to work with Common Music. http://www.notam02.no/arkiv/doc/snd-rt/ --

[linux-audio-dev] Midi/OSC help

by Olivier Guilyardi

Hi, I am thinking about adding midi or/and osc support to Jackbeat (http://xung.org/jackbeat). My idea is to use a hardware midi controller such as the evolution uc33 to control pitch, volume and muting on every tracks. This would help using Jackbeat for live performances. I have never coded with midi, neither with osc. What's the fastest and smartest way to achieve this idea ? Regards -- og

[linux-audio-dev] help with writing a plugin (part 2)

by Artemio

Dear friends, thanks again for your help with my ports definition yesterday - with it, I created a clipping booster plugin with three control ports and it works perfectly. However, today I added the fourth port, following all rules I learnt, but I get the same segfaults as yesterday. If you could have a look at the sources (attached), it would be of fantastic help for me. Once again, please forgive me, I am a real newbie at this and things that are very obvious for you are not such for me... But as I understand all these bells and whistles, I will be more silent ;-) Thanks a lot again. Regards, Artemiy.

[linux-audio-dev] help with multiple control ports

by Artemio

Hello all! I have a problem with creating a plugin with more than one control port. In the attachment you'll find "booster-simple.c" which has one "Gain" port and my attempt to add a second port in "booster.c". For some reason the latter cannot be used - the sources seem to be correct, it compiles fine, but then if I test with "applyplugin" it segfaults and other hosts complain about a malloc() error and hang. Debugging shows that ports are not properly connected: [connectPortToBooster] setting BOOSTER_INPUT1 [connectPortToBooster] setting BOOSTER_OUTPUT1 [runMonoBooster] applyplugin: booster.c:112: runMonoBooster: Assertion `psBooster->m_pfGainValue != 0' failed. ...but I cannot investigate further as my C is very basic. I would really appreciate any help. I based my plugin on the amp.c from the SDK, and I see that in example plugins like simple delay (where there is more than one control port) memory allocation is done differently, but I just don't know how to properly apply these techniques to my plugin... Thanks very much! Artemiy. P.S. I've sent a message with a 50Kb attachment and it's in moderation queue, but these sources are newer.

[linux-audio-dev] All things LADSPA, your input please

by Tim Goetze

Greetings, you may have seen the recent mail on this list looking for an author doing a LADSPA article in a german Linux magazine; I've decided to step in. Now, while I do have some knowledge of the technical nature of LADSPA I can't truthfully say I know all the plugins and hosts out there as well as they deserve. So, I'd love to hear from you: what do you write or use (hosts and plugins, realtime or offline, a shameless plug for your efforts is welcome too!), any issues you take with it, LADSPA vs. VST, the DSSI expansion etc etc; in short, anything you find worth noting is appreciated. Thanks, Tim

[linux-audio-dev] "Call for an Online-Demonstration against Software Patents"

by Jens Radloff

Hi, Let me inform you about the online demonstration against the patentability of software (=software patens) which the Commission of the European Union wants to introduce. As far as I understand the process of passing the appropriate bill in the institutions of the EU, the patentability of software could be possible from July 2005 on. There is a site, run by among others Attac Germany, where you can protest against this, by uploading a picture of yourself: http://demo.stoppt-softwarepatente.de/index.php?content=demo&lang=GB "So far 3883 people have demonstrated here. The more people participate, the clearer a joint picture of the protest will be shown. Short before the decision in the European Parliament we will print this picture on a huge banner and show it in front of the European Parliament in Strasbourg. This way you can also be a part of the international demonstration." Regards, Jens ___________________________________________________________ Gesendet von Yahoo!

Re: [linux-audio-dev] LilyPond version 2.6 available - Music Notationfor Everyone.

by Chris Cannam

Albert Graef writes: > that's great news. Certainly is! > Has Rosegarden been updated to a newer Lily yet? Last > time I looked, they were still generating 2.0 code. :( Rosegarden's been able to generate 2.2 code for ages, and 2.4 for a while - though I can't quite remember whether that was in the 1.0 release or not. We're partly but not completely up to date with 2.6. I might well look at that this week, unless anyone else offers. Our Lilypond output is not terribly well structured for any version, so a bit of an overhaul might be nice too. Chris
