[linux-audio-user] [PATCH] envy24control widget limits, version 2

by Ross Vandegrift

Hello, The first version of my patch had a few glaring errors. This update fixes the following issues: * HW In level meters were broken * The last PCM Out meter was broken * S/PDIF channels can now be controlled with -s, --spdif * The Patchbay/Router and Analog Volume tabs now accurately reflect the number of requested channels in all cases. This update does not include the requested vertical layout changes. If I have the time, this is on my TODO list. The patch against 0.9.3 is included below, and available from http://poplar.seitz.com/~ross/envy24control/envy24control-control-limit-v2.… Testers would be greatly appreciated - especially those with cards other than the Delta44. -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon.

[linux-audio-user] Audio Prototyping with Pure Data

by Levi Burton

>From the Inside Gamasutra newsletter: "Audio Prototyping with Pure Data" by Leonard Paul http://www.gamasutra.com/resource_guide/20030528/paul_01.shtml Interactive game audio requires combining content and code. Unfortunately, composers often have little control over how the code works and thus how the audio will sound in the final game. What's needed are tools that let the composer prototype the audio and show the programmer. One such tool is Pure Data, an open source program that is extensible, powerful, and, well, free. -- Levi Burton http://www.puresimplicity.net/~ldb/

[linux-audio-user] SLUGAMuSIG - Audio/ Music Group Second Meeting (fwd)

by Conrad Parker

June meeting of the Sydney Linux Audio/ Music Group http://www.slug.org.au/events/detail.html?id=71 ----- Forwarded message from Denis Crowdy <dcrowdy(a)pip.hmn.mq.edu.au> ----- Second Meeting of SLUGAMuSIG - Linux Audio/ Music Special Interest Group When: Saturday, June 14; 10am onwards Where: Macquarie University, Department of Contemporary Music Studies, building W6A, room 607 All interested in music/ audio and Linux are invited for the second gathering of the group. A more detailed list of proposed discussions will follow shortly, but the general plan is a demonstration/ discussion in the morning, followed by an open session of jamming/ coding/ talking in the afternoon. All levels of interest are welcomed. A relevant map of Macquarie is at http://www.ccms.mq.edu.au/crowdy/macmap.html. The best way to get to the Music Department (on the 6th floor of building W6A) is from the Balaclava Rd entrance (opposite Woolies from Epping Rd). The closest parking is "W4", and costs $6.00 for the whole day. For people arriving at various times through the day, the front door might be locked, but we'll keep an eye out, or call me on 0408 478 802.

[linux-audio-user] jc-a script for jack

by Jonathan Kraut

jc A python script for controlling jack connections http://home.earthlink.net/~krautj/ jc is an interactive command-line script that enables you to connect and disconnect jack ports with a few short keystrokes. It requires the pyjack module by Andrew W. Schmeder and was built with python-2.2. You may also choose to sever all ports from a given port or disconnect single ports. There is a help screen. It's the first thing I've ever written, let alone ever written in python, and comments and improvements are welcome. Good luck! And thanks to everyone developing audio software for linux! -- Jonathan Kraut Current email: krautj(a)earthlink.net (changes from time to time) or Permanent email: jak76(a)columbia.edu

[linux-audio-user] [PATCH] envy24control widget limits

by kevin ernste

<<< You were right about the number of faders with the Delta 1010 - I <<< checked in the studio, and I only see HW In 1-8, PCM Out 1-8 and the <<< two S/PDIF faders. Two rows would do, or maybe three if you put the <<< S/PDIF faders in line with channels 1 and 2. Then you could specify <<< how many rows and how many channels you wanted... Many thanks to Ross for his excellent work here. On the topic of space and functions on the envy24control panel, I had some questions and ideas. I appologize for the length! First on space, could you not cut the number of graphical channel pairs in half? In other words, why are there "stereo" linked fader pairs for each individual mono PCM 1-10? I noticed that on the Mac/PC version of the delta mixer... http://www.midiman.net/products/m-audio/images/delta-pane3.jpg ...these actually represent stereo pairs. 1 is the left channel of the first pair (PCM 1), 2 the right (PCM 2), etc. Channels can then be paired/unpaired as desired ("stereo linked"). This setup saves alot of real-estate meaning only 5 pairs on the panel for outputs and 5 for inputs even on the 1010 (though it does mean a split vu meter for each). The first 4 are analog PCM pairs, the last two are the stereo pair for SPDIF. Outputs: | 1 | 2 | 3 | 4 | 5 | PCM 1/2 PCM 3/4 PCM 5/6 PCM 7/8 SPDIF L/R (9/10) ...likewise for Inputs. As it stands now, not only is there duplication, but it is also impossible to link stereo-pair levels on the panel. As to the additional hardware output control, this is absolutely necessary when, as in my case, the analog outputs go directly to powered monitors. Without them, levels must be controlled by exterenal harware. But couldn't this functionality be built into to the PCM out's already there? Right now on my Delta 1010 (ALSA 0.93 in PlanetCCRMA) these PCM-out faders/mutes do nothing to the signal level at all unless I route it somewhere internally, like to the "Digital Mix". Shouldn't these faders control the hardware-out level when routed directly from PCM Outs in the Patchbay (as they all are by default on my machine)? Thanks again for everything. Your work is much appreciated. Very best, Kevin ===== "I should prefer this note not be read or, if skimmed, that it should be forgotten." - Mallarme __________________________________ Do you Yahoo!?
