[linux-audio-user] ecasound interactive mode

by Paul Coccoli

How do you add a second chain in ecasound in interactive mode? I can create one chain that reads a file for input and outputs to jack, but if I try to add another chain I get the following: ecasound ('h' for help)> c-add t2 (eca-control) WARNING: This operation requires that chainsetup is ... disconnected. Temporarily disconnecting... - [ Engine exiting ] ----------------------------------------------------------- (eca-control-objects) Disconnecting chainsetup: "command-line-setup". - [ Chainsetup disconnected ] -------------------------------------------------- (eca-control-objects) Added chains: t2. (eca-chainsetup) Unable to connect: Chain "t2" is not valid. Following errors ... were detected: (eca-chainsetup) Chain "t2" is not connected to any input. All chains must have ... exactly one valid input. (2.1-NO-CHAIN-INPUT) (eca-chainsetup) Chain "t2" is not connected to any output. All chains must have ... exactly one valid output. (2.2-NO-CHAIN-OUTPUT) ERROR: Can't reconnect chainsetup. Well, ok, so then I quit, restart with 1 chain again, THEN create new input and output, and try to create a second chain: ecasound ('h' for help)> ai-add jack_auto (eca-control-objects) Added audio input "jack_auto". ecasound ('h' for help)> ao-add jack_auto (eca-control-objects) Added audio output "jack_auto". ecasound ('h' for help)> c-add t2 (eca-control-objects) Added chains: t2. ecasound ('h' for help)> c-list t1,t2 ecasound ('h' for help)> start (eca-chainsetup) Unable to connect: Chain "t2" is not valid.

Hmm. If a chain MUST have one valid input and output, but inputs and outputs need to be connected to a chain, THEN ITS A PARADOX AND MY HEAD EXPLODES! Seriously, I'm tryin the most basic thing in the world and I can't do it. Maybe it's just too late at night... paul

[linux-audio-user] Indentity change?

by Folderol

I was somewhat dismayed to find that both my e-mail handle and given name are extremely common on the net, and I'm somewhat concerned at the prospect of possible confusion as other musicians, DJs etc are included. I have taken to using the name Will J Godfrey on all ID tags for my music, and on my homepage title. It will probably take a while to change all the existing files. Eventually I'll move the website too, but will maintain a link for the foreseeable future. This is just to let you know so you won't think one of 'me' is being ripped off! -- F

[linux-audio-user] Generating x frames of silence wav.

by Alex Polite

I need to programatically pad a wav file with x frames of silence. I figure the best way of doing is to generate a wav file containing x frames of silence and concatenate the generated file with the original. Problem is I don't know how to generate the silence. The method I'm using now feels kind of backwards. I generate two sine waves that are phase shifted in relation to one another and then I mix them so that they cancel one another out. sox -t nul /dev/null /tmp/tmp1.wav synth $secs sine create 1 0 0 sox -t nul /dev/null /tmp/tmp2.wav synth $secs sine create 1 0 50 soxmix /tmp/tmp1.wav /tmp/tmp2.wav /tmp/tmp3.wav sox /tmp/tmp3.wav -r 8000 /tmp/silence.wav I guess there's a more elegant way of doing obtaining the same result? I'd also like to be able to specify the amount of silence to be generated in frames rather than in seconds. -- Alex Polite http://flosspick.org - finding the right open source

[linux-audio-user] My two best songs so far

by John Anderson

Hi y'all Both songs use Ardour & jack to hang it all together, drums sequenced by Rosegarden and fluidsynth playing the fluid soundfont and ns-kitfree. With LADSPA - Freeverb, SC1, 4-band parametric, TAP de-esser on one track. Mono amplifier and low and high pass filters in some places. I did send the songs through jamin at some point and liked the results, but I can't remember if it's these versions or not. Many thanks to authors and contributors for these programs. I'd love to say what genre they're in, but I don't know. World-music-ish would be the closest. I like to use real instruments played by real people, and I try to keep effects to a minimum. 2.7M, 3:45. http://www.semiosix.com/songs/firelightless.ogg One of those songs that just came together all of a sudden. I remember running dripping out of the shower to write down the lyrics. Made with electric & acoustic guitar, fretless bass, violin and cello initially by Rosegarden. Later I recorded live (non-free) violin and cello with the help of a bcf2000, which sadly isn't working 100% for some reason. 3.1M, 4:01. http://www.semiosix.com/songs/thirty.ogg This song started life about 15 years ago on acoustic guitar. Electric guitar, fretless bass, drums, percussion and vocals added in the last year or so. I've posted it here before, and I've improved it since then. I'm still not happy with the sequenced percussion track, but my percussion skills aren't up to that particular task. Of course, I wouldn't be posting these here if I didn't welcome feedback of all kinds. I'm especially interested in what feelings the songs evoke and what mental movies you see. thanks in advance John

[linux-audio-user] Three last tracks

by yves_p＠nnx.com

Hi. Thank you again for the very nice things you said about the last tracks :). I'd like to submit three last ones to your listening, hoping for all kind of thoughts and advices, especially which could help me improving the sound, the mix, and also the use of Jamin. Then I hope I'll be ready to release this music on a web site, of course under a free licence, with some other tracks. First, a (very) personnal version of a very well known song : http://ypotin.nerim.net/astronomy_domine.ogg (Syd Barett) 5,7 M Then, an arrangement I wrote of a jazz standard : http://ypotin.nerim.net/lennies_pennies.ogg (Lennie Tristano) 5,4 M Finally, a more personnal track, a bit long, about which I'd be really glad to hear your comments : http://ypotin.nerim.net/oceaniques.ogg 11,4 M Thanks in advance for any kind of thoughts about all this, and my apologies if my English is rarely as clear as I'd liked it to be :). Best, Y.

[linux-audio-user] fst-1.8 wont work! [Unhandled exception (thread 0009)]

by Benjamin Fabricius

Hi all, I am still having a !"§$%& hard time getting fst to run on my designated embedded vst server. I've tried: wine-20050628 wine0.9.14 latest source and now wine-20050725 with: fst-1.6 fst-1.7 and now fst-1.8 I am tending towards the team up of wine-20050725 and fst-1.8 because on my local development host i get this output which makes me hope I'm on the right route: ben@barney:~/wine-20050725_vst_testing/usr/bin> ./wine ../../../fst_vst-1.8/usr/bin/fst.exe.so /mnt/v/testsuite/tau/Tau.dll yo... lets see... can't connect to JACK <- dont have jack running on this machine This seems very promising doesnt it? For some reason though i keep on getting following error when running fst on my vst server... and this error also occured with other wine versions, allthough without the debug info.

And just as a note: Jean Piche has announced that a new version of Cecilia should arrive Real Soon Now, hopefully in a multiplatform update. Otherwise, Musix looks pretty cool.

by yves_p＠nnx.com

Hi :). Here are two other tracks : http://ypotin.nerim.net/seven_bells.ogg http://ypotin.nerim.net/no_joe.ogg They are very different from each other. Thanks in advance for all comments :). Cheers, Y. P.S. Of course, when all this stuff will be achieved, there will be a web site to present this music, under a CC licence. I hope the site will be up before the end of June.

[linux-audio-user] USB-Midi

by Marcel Karras

Hello all, I'm looking for an USB midi device in order to record some stuff with my keyboard. The "SWISSONIC MIDI-USB 1x1" seems to be quite cheap but I couldn't find any information on usability with linux. The Edirol UM-2EX you discussed some threads ago seems to be okay but I don't need two midi outputs. Any suggestions?
