There are some issues with video cards and sound: * First of all I want the video card to be quiet! I do not need the fastest and hottest one... * I guess, onboard grafics are problematic, as they don't have separate RAM. Memory operations could be slowed down in applications. Is this true? Are there other sound related issues I should be aware of, when choosing a video card? Robert Epprecht

[linux-audio-user] New tunes.

by Patrick Shirkey

For those into a bit of raw, lofi, hard rock check out some new tracks which were recorded with my Linux powered music machine: http://www.djcj.org/audio/Voipit/ You can read about the machine here: http://www.boosthardware.com/products-mahine.php3 Click on the "rua" link. All the recordings were done with ardour and an hdsp. -- Patrick Shirkey - Boost Hardware Ltd.

At that point, the rockets disconnected from the timer, leaving them strewn around the street. Tethered to the now toppled cart, the donkey was unable to escape before the arrival of U.S. troops.

[linux-audio-user] voice note recorder

by Helge Hielscher

Hello, hope this is the right list to ask. Does anybody know if there is an audio voice recorder for linux? Like a normal audio recorder, but one that automatically switches between pause and record. The only voice note recorder I found on the web is Windows only and has a huge feature list. http://www.xemico.com/anr/index.html TIA, Helge

[linux-audio-user] Rewrite sfxload for native ALSA

by Mark Constable

You have to load a soundfont with the utility sfxload (available > in the aweutils package). This also implies that you need to setup > OSS-compatibility support in ALSA since the awe utils use that. I anyone aware of ANY non-OSS tool to load soundfonts into an SBlive card ? If not, would anyone be interested in looking in to how to rewrite sfxload so it, at least, uses the native ALSA API ? Even with ALSA in the 2.6 kernel (yay, no more modules) and most apps now converted to ALSA/jack I am still stuck with this small but useful utility. I get around it by simply not using the the soundfont capability of my SBlive. Pity. --markc

[linux-audio-user] Success with midi

by Eduardo Guerrero

Hi, this success story with my midi setup is dedicated to all of you who have helped me these days. I'm finally being able to play with my keyboard the sounds generated by ZynAddSubFX hearing them coming out from the speakers as I play. That's great by itself due to the almost unlimited capabilities of Zyn. Then I got stereo sound which was previously unavailable. Frankly I don't know the reason, but when I upgraded from Mandrake 9.1 to 9.2 panning started to work properly. Then I have Hydrogen. I'm making some good beats with it and playing along with my keyboard. This brings me to my 2 questions: - Is there a way to mix levels of the audio streams going to the alsa_pcm port? I have the possibility of turning up or down the volume in Zyn but it isn't as flexible as it could be since, in this case, Hydrogen doesn't have a volume control (or I haven't figured out where is it). - Can I use some FX on the audio stream? A filter bank, a reverb or a delay line can do wonders to the already-wonderful sound I now have. With audio stream I'm referring to the mixed sounds coming from Zyn and Hydrogen to the alsa_pcm port (labeled as input, but in my point of view it could be the output port --sorry for being selfish here). - Is there a way to share bpm information between apps? For syncing delays it would be great not to have to fire up the delay calculator. I don't have many, if any, programming skills but I guess it would be as simple as using an environment variable. Perhaps the functionality is already there but I haven't found it or nobody uses it. For mixing levels right now I'm thinking that a possible solution could be to program the whole song in Hydrogen and then using it on MusE or Rosegarden but a lower-level mixer (lower in the sense of operating at the alsa level) seems conceptually more interesting. Thank you for the previous help received and for the future comments this post will surely arise. The spirit on this mailing list is beautiful. Eduardo.

[linux-audio-user] How to get a list loaded soundfont ?

by mutah

Hi, I've got an audigy and I'm happy to be able to load soundfonts with sfxload from awesfx. One thing I can't figure out to do is to display a list the loaded soundfont.... As somebody some success about that ? I'm asking this question because I'm writing a script to load soundfont map in my rosegarden project. I've managed to dump bank and instrument from a sf2 file (with help of sf2cfg) into rosegarden xml format, so I can choose the correct instrument for rosegarden midi tracks. (May be this script could be useful for fluidsynth user too) Thanks fo any clue

[linux-audio-user] New Linux Audio Column in Linux Journal

by Joern Nettingsmeier

hello linux audio enthusiasts! reading lwn.net this morning i found that the linux journal has a new linux audio column in their online edition, written by dave phillips. the current issue is at http://www.linuxjournal.com//article.php?sid=7283 . the content of this first issue will not be news to you, since it's basically a plug for the world's finest linux audio mailing lists, which you already seem to know about :) still, it's an interesting read, and it has had an effect already: about 30 new subscriptions (in addition to the usual continous growth) since wednesday... (see http://www.linuxdj.com/audio/lad/subscribe.php3 .) to all new readers: welcome aboard! best, jörn -- To someone whose only tool is a hammer, each problem looks like a nail. - Edsger W.

[linux-audio-user] Ecasound 2.3.2 released

by Kai Vehmanen

1. A short summary of changes Support has been added for libsndfile. This allows to access a number of new audio file formats such as W64, PVF and VOC files. Integration with libaudiofile and MikMod has also been improved. Bugs in the native Python ECI implementation have been fixed. Rubyecasound, a Ruby ECI implementation, has been added to the package. A serious memory-leak in list handling functions of the C ECI implementation was fixed. This bugfix also affects C++, Perl and PHP ECI implementations. Compiling Ecamegapedal works again as the header files missing from the previous 2.3.1 release are now again included in the dist-package. Many minor bugs have been fixed. --- 2. What is Ecasound? Ecasound is a software package designed for multitrack audio processing. It can be used for simple tasks like audio playback, recording and format conversions, as well as for multitrack effect processing, mixing, recording and signal recycling. Ecasound supports a wide range of audio inputs, outputs and effect algorithms. Effects and audio objects can be combined in various ways, and their parameters can be controlled by operator objects like oscillators and MIDI-CCs. A versatile console mode user-interface is included in the package. Ecasound is licensed under the GPL. The Ecasound Control Interface (ECI) is licensed under the LGPL. --- 3. Changes since last release * Rubyecasound, a Ruby ECI implementation, has been added to the package. Developer documentation can be found at <http://eca.cx/eci>. Rubyecasound was developed by Jan Weil. * Some files were missing from the previous 2.3.1 release dist-package. This caused the "make check" test procedure to fail, and also prevented from compiling Ecamegapedal against 2.3.1. In 2.3.2 the missing files are once again included in the dist-package. * Libsndfile support has been added to Ecasound (development item 'edi-33'). Support for libaudiofile has also been improved in this release. The user can now compile in support for both libraries at the same time. It is possible to use command-line options to select which library to use for a given file. Similar improvements have been made to the MikMod support. See the ecasound(1) man page for more details. * Some bugs in libsamplerate integration have been fixed. Upgrading to libsamplerate version 0.0.15 or newer is recommended. This release contains a few important fixes that affect Ecasound. A few examples of resampling with Ecasound have been added to the docs: <http://www.wakkanet.fi/~kaiv/ecasound/Documentation/examples.html>. * A severe memory-leak bug was found and fixed in the C ECI implementation. This bug affects applications that heavily use EIAM commands that return lists of strings. The C ECI is used by C++, Perl, PHP and Python ECI implementations. * Bugs in the native Python ECI implementation have been fixed. The C-based Python ECI implementation is still selected as the default, but you can override this with the '--enable-pyecasound=python' option to configure. Note, 'native' here means that ECI API is implemented without linking to any Ecasound libraries. Instead the ECI implementation forks 'ecasound' binary on the background and communicates with it using pipes. This allows for clear decoupling between ECI apps and specific Ecasound version. More information about ECI can be found at <http://www.eca.cx/eci>. Full list of changes is available at <http://www.wakkanet.fi/~kaiv/ecasound/history.html>. --- 4. Interface and configuration file changes None. --- 5. Contributors Patches - Accepted code, documentation and build system changes Jan Weil (2) -- rubyecasound ECI implementation, new docs Mark de Wever (1) -- typo in libecasoundc-config usage Kai Vehmanen (various) Bug Hunting - Reports that led to bugfixes (items closed) Fernando Pablo Lopez-Lezcano (1) -- preset.h not installed Jan Weil (1) -- the ecacontrol.py bug --- 6.
