[linux-audio-dev] anyone interested to develop a new apps ?

by dubphil＠free.fr

Hello, I want to setup a sound system with linux. For this, I need an app that could split an audio file in four tracks in order to add them separately some effects. I tried to achieve this using Jamin which have this kind of "Crossover" functionnality, but it is defenetly not usable for what I need. The ideal application should not be too complex : it should be compatible with Jack and could just get a stereo channel for input and provides 4 stereo channels. The 4 stereo channels would be the result off a crossover spliting by frequency ranges of the input stereo channel. we could give a default preset like this : 1st stereo channel : low 2nd stereo channel : low-mid 3rd stereo channel : high-mid 4th stereo channel : high of course thoose ranges should also be set manually. each channel could have the gain controlled and could have assigned 4 effects with LADSPA plug-ins. each slider or knob should be midi controlled (I know that Jack Rack already does this). Does this kind of apps should take a long time to be developped ? I'm not skilled to undergo this kind of project alone as I'm a poor PHP/Perl and little Python developper. Anyone interested for this kind of project ? Kind regards Philippe

There was a thread about a project of "open > source" graphic card recently on lkml. And I posted a [possibly OT] rant to that thread about how this was a waste of time and how you could REALLY make a killing with open sound hardware. http://lkml.org/lkml/2004/10/23/292 I got one "right on, brother" response via private mail and that was it. But then again half the kernel guys don't have sound cards in their machines ;-) Lee

[linux-audio-dev] TAP Plugin pull-down menu problems

by Doug McLain

Using CVS tap-plugins and cvs ardour, I cannot select any of the other reverb styles in Reverberator, and maybe only one or two of the choices in mono Dynamics. Sorry for cross posting but I'm not sure if it's a plugin or ardour issue :) Doug -- http://nostar.isa-geek.com/

[linux-audio-dev] [ANN] liblo 0.15

by Steve Harris

liblo is an implementation of the Open Sound Control[1] protocol for POSIX systems. It is written in ANSI C and released under the GNU General Public Licence. It is designed to make developing OSC applictions as easy as possible. http://plugin.org.uk/liblo/ This release adds some OSX compatibility fixes from Taybin Rutkin, support for OSC multipath pattern matching courtesy of Daniel Holth's pattern matcher and I've added bundle i/o. Liblo now implements everything in the OSC specification except type arrays. Pattern matching and bundles are largly untested, and should be treated as alpha quality, but should work. If you are using server threads or the nonblock API then bundles should JustWork(TM), if you are polling on the server fd then you have some work to do. There are API calls for detecting if/when there are scheduled messages. - Steve [1] http://www.cnmat.berkeley.edu/OpenSoundControl/

Well, the ALSA support shall be achieved sooner or later :) But it's true that there is still a significant gap between the product release and the support on Linux. Once people recognize the importance of Linux desktop, this gap will be decreaed, I guess. My biggest concern is the chaos like what has happend on USB audio/midi (or look at ACPI). I really hope such a theatrical confusion won't happen on fireware audio. The precised specification doesn't always lead to a good result :) Takashi

There was a thread about a project of "open > source" graphic card recently on lkml. I know about the project in question, as I participate in the discussion about it. an open design sound card would be even easier to design... an atmel microcontroller and a pair of ADC / DAC chips should be enough to desing something with a USB port. now for the firewire thing, I guess a xilinx chip can do it, and those are not that expensive either...

[linux-audio-dev] Novation ReMOTE, Speedio & XStation

by Nick Dowell

Hi, I noticed there has been some discussion as to whether novation usb midi and/or audio products will work with linux: http://www.music.columbia.edu/pipermail/linux-audio-user/2003-August/ 005765.html I can tell you that the audio side of all out usb products are usb class compliant, so they should work with the usb audio class drivers. If they don't, please let me know. The MIDI communication is not class compliant. It is a very simple protocol though, and should be easy to implement. If anyone wants information to write one we'd be more than happy to give it. Thanks.
