[linux-audio-dev] provding plugins with various in/out counts vs. using splitters-mergers

Splitter-plugin vs plugin-splitting? :) At first I agreed that the splitter was the solution, and I wrote one, only to find one already exists in the SWH package. The argument is that this is clumsy and not an optimal solution. After hearing this argument, it does seem like a cleaner, faster solution to have available plugins in various connection formats instead of building the connections from lego's. I am in no way an authority on this though, so I am going to forward this to LAD, as I think it pertains to all the plugin projects. There was recently a thread on ardour-dev regarding connections and plugin counts that is probably going to start all over again, but discussions are fun anyway, arent they? :) Doug -- http://nostar.net/

[linux-audio-dev] Feasibility of Crestron like Linux Based Whole House Audio System - Multisource / Multizone Capable????????????

by Steve Vanechanos

New to the group. Please forgive any unintended breaches of protocol. I just built a house and had it prewired for stereo speaker pairs in 6 rooms / zones in addition to cat5 in each zone. My intention was to purchase a multisource / multizone audio system from a high end integrator. After reviewing several options - Crestron and Niles primarily - I ended the review dismayed with the cost and overall approach of the "main stream" solution providers. I'm a UNIX guy going back to 1983 - Altos8600 running a 5Mhz Intel 8086 with 512Kb RAM, 20Mb 8" Winchester hard drive and Microsoft's version of Xenix. I'm wondering if the present state of the Intel/AMD powered PC with Linux is robust enough to control multiple sources (4, 6 or 8) like digital cable box, directv receiver, XM radio, CD player(s), etc. and route the output to multiple zones/rooms (4, 6 or 8) in an effective and cost efficient manner. The Crestron approach would cost me around $10K - so I've got some money to invest on development if necessary. Once again, my apologies if I've breached any list/group protocol with this post.

[linux-audio-dev] [ANN] Ceres V0.41 and Snd-ls V0.9.1.5

by Kjetil Svalastog Matheussen

CERES ***** "Ceres is a simple program for displaying sonograms and for sound effects in the frequency domain." Except that its not that simple anymore... 0.40 -> 0.41 ------------- -Fixed a (horrible) bug that caused ceres to crash on newer linux distributions. -Simplified the install process a lot. pygtk1, libglade and sndlib is now included in the distribution and is/can be installed automatically if needed. -Connect to jack-server right after starting up ceres, not right before playing for the first time. http://www.notam02.no/arkiv/src/ SND-LS ****** 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. 0.9.1.2 -> 0.9.1.5: ------------------- -Made the apply-button always apply to selection if there is a selection. -Removed some options from the edit-menu that interfered with the way snd_conffile works. -Made the insert-option in the edit-menu insert monofiles into the currently selected channel. -Added libxt-dev to the list of required packages. (Thanks to robin) -Made mono-files play in both left and right channel when using Jack. -Short fix for the nodeline-class. http://www.notam02.no/arkiv/src/snd/ --

[linux-audio-dev] Linux friendly, portable digital recording devices?

by Ian Howard

Hey all, We are looking for some portable digital recording devices with the following criteria: - very small - durable - near $100 ($100-150) - usb compatible - linux + windows friendly - mic-in with a reasonable signal-to-noise ratio - descent quality recordings - battery powered We intend to distribute about 10 - 20 of these units to radio journalists in Mali, whom will use these devices to collect material for their programs which they can then edit in Audacity and broadcast on the air. We are looking at devices such as the iRiver 190T Any one have any experience with such devices, in particular using them with linux?

[linux-audio-dev] WXWidget/Portmidi cross platform dev

by Dubphil

Happy new year 2005 to all LA fellows ! Recently I have contacted a manufacturer (WaveIdea) to help them adapting their hardware (a great midi Interface unit http://www.waveidea.com/en/products/bitstream_3x/) on Linux and they are very opened to collaborate with the community. They are developping with the cross platform libraries WXWidget and Portmidi, libraries used for example by "Audacity". they have two softs. - a proprieritary soft : the firmware upgrader, I have compiled it on Linux and it looks like it will work very well on this platform. - a "future" open source soft (I succeed in convincing them to make it open source) that has not been developped completely. It is the configuration tool of the unit. The developpment should consist in : - linking the UI action to the low level functions that should send/receive Sysex between the soft and the unit. - Improve the UI itself. Anyone interested to help finishing this open source soft is welcome, just contact me. Philippe

[linux-audio-dev] Re: Need tips to get OSS midi configured

by airplays55＠yahoo.com

Thanks for the responses - the reason I didn't give more details is mainly because I don't know where to begin troubleshooting. Firstly let me explain why I need this to work on knoppix. I boot knoppix from a customized image on a compact flash card, so I've been able to add and customize a lot of software, and it runs all sorts of things for me like a webserver, proxy, browser, etc etc. I have a dedicated computer at my house that is always running knoppix (without harddrive) which is always on since there is no harddrive to eventually crash. For my serious audio work I have another computer that runs midi software I've been using since the late 80's (Dr. T's) in an Atari ST emulator, and this system does everything I need for now. Although I've been dabbling with Agnula and ALSA (with no luck yet), I still need to get the knoppix system working with rosegarden2 so that we will have a midi scratchpad to save song ideas with, to be later imported into a different system with rosegarden4 or cakewalk sonar or whatever. OK here are some details on my system. The computer is a gateway P2/266, and I have three soundcards (and a usb interface) that I've tried booting with, but knoppix doesn't autoconfigure the midi ports on any of them, although knoppix is able to identify and configure the audio portion of the soundcards. My hunch is that I should be able to manually get the midi portion to be recognized if I knew what to do. The soundcards I've tried are 1) a digital research ESS1869 ISA card, 2) an AVANCE LOGIC als-100 ISA card, 3) yamaha YMF-724 PCI card, and 4) a midiman midisport 1x1 USB interface. When I run rosegarden2 (that comes included in knoppix), the midi setup has /dev/null as the midi device. If I change it to /dev/midi, or /dev/sequencer, it says "device invalid or busy" when I run sndconfig with the yamaha pci card installed, it says "the yamaha corp ymf-724 (pci) is not currently supported" although I still hear audio through the wav output. when I run sndconfig with the ESS1869 ISA card installed, it says "no PnP or PCI soundcards were found - choose from list" then I choose "ESS1868 audiodrive" from the list, then I get a segmentation fault. I checked my /etc/modules.conf - I don't see an entry "snd-seq-oss", but the top of the file says run "update-modules" instead of editing modules.conf directly. So thats where I am now; I don't know what modules I need loaded (snd-seq-oss?) and I don't know where to find or how to add modules (yet). What can I try next? Any tips will be much appreciated! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

[linux-audio-dev] UPnP AV Media Server for Linux ?

by Andreas Kuckartz

UPnP (http://upnp.org) seems to have been adopted by many/most producers of audio streaming devices. I am looking for Open Source Media Server software for Linux which is accessable by UPnP AV Media Renderers. Any suggestions? Interesting material which I have found so far: Overview of UPnP AV Architecture http://www.intel.com/technology/upnp/download/UPnP_AV_Arch.pdf Linux SDK for UPnP Devices 1.2.1 (libupnp) http://upnp.sourceforge.net/ LINUX UPNP INTERNET GATEWAY DEVICE http://linux-igd.sourceforge.net/ CyberLink / CyberMediaGateway http://www.cybergarage.org/net/index.html Intel(R) software for UPnP technology http://www.intel.com/technology/upnp/index.htm Cheers, Andreas
