Lightweight WM that can be used without any issue with audio applications

by Ralf Mardorf

I switched from Xfce4 to JWM. JWM does work with all apps excepted of QjackCtl. Often I need to kill QjackCtl, because the Connect window always is above all other windows and it's impossible to close it. I don't want to use a tiling window manager or a WM that is nearly as bloated, as DEs such as Xfce4. What WMs do you use? A lightweight DE would be ok too, as long as it isn't unstable and has got no dependencies to GNOME software. Bad coded stuff like Enlightenment is a complete no-go. I want to handle windows with the mouse, they should be free to overlap and I don't want to experience issues, even not issues that happens seldom, workspaces should be editable. JWM is nearly perfect, excepted of the QjackCTL issue.

another cpu question

by Ede Wolf

Hello all, I may be putting together a box dedicated just to act as a multitrack effects unit - without planning any recording. The effects stack will for most channels most likely look like this: reverb, delay, EQ and maybe one of flanger, chorus or rather seldomly compression. Anyway, just the classics, planning so far to only to install the calf and invada lv2 packages. Though I am open for recommendations here, too. And of course I am looking for a suitable effects host/rack. However, I do suppose, the reverb will be the most cpu consuming item and I am wondering, what feature an a cpu should I be primarily looking for? I guess, for effects, especially reverb, the floating point performance will be paramount? As HT generally has a bad reputation for audio, currently, the AMD FX-8350 is on top of my list, as the floating point preformance is said to be rather good and lots of cores should be ideal for running lots of effects in parallel - though unfortunately not every core does have its on FPU. As it is not going to run 24/7, the insane energy consumption is somewhat acceptable. But, beeing no coder, I may be completely off track with my conceptions here, so I am asking for some more insight or alternative recommendations, maybe even with a short reasoning Thanks Ede

Smoothing congas

by jonetsu＠teksavvy.com

Hi, Congas (in this case Wavedrum congas # 19) have sometimes hits louder than others. Eg. the player hits more forcefully at times. What would be a good way to even out the output (recorded in Ardour) so that the stronger hits do not stand out as much in the mix ? Cheers.

Each program, opensource or not, has its own system and ne'er the 'twain do meet. So one restricts to one program, no other choice. Microsoft is so big so makes its own standards, its own rules, changes them at will (example rtf), but they are not in the DAW business. Just many programs run on their platform so may use some of their file-structures. What if the programs we use here, on this list, were inter-operable? Ardour/Harrison, Qtractor, Muse, Rosegarden, etc. We have more choices than does Microsoft. What if Tracktion (proprietary, now supporting Linux!) were brought on board? I do not think it is so far-fetched if there be a will to do so. One opensource library to service this, done once. (I no longer have my old posts, proposals for this. Discussion was a while back.)

A short story: from zero to recording the drums in a budget

by Carlo Ascani

Hi guys, I own an acoustic drum, and I wanted to record it. My set looks like this [1], and I wanted 8 mics to record it. So, starting from *just* the drums, I bought everything I needed: 1. The Mixer I got a second hand Soundtracs Topaz Micro (I used its Inserts as Direct Outs) for 220 euros 2. The PC I got an IBM Thinkcentre 8215 for 50 euros 3. The converters I got an Echo Layla 20 for 50 euros, it has 8 analog ins and it is really well supported by alsa. 4. The Monitors I got a pair of second hand KRK Rockit 5 for 150 euros 5. Cables and mic stands Got them for around 250 euros 6. The mics I got an Audix D6 and a Sennheiser e609 for kick, a Revox m3500 and a Beyer m610 for the snare, two Sennheiser e609 for the floor toms and a pair of Sennheiser e614 as overheads. The total cost of those mics (second hand) is 600 euros. So, the total price of the whole thing was around 1320 euros! Here are some audio clip of the result, dry recording [2] and processed with some eq, compressor and reverb [3] So guys, what do you think? If I would improve the quality of my recordings, where should I spend more money?

[ANN] Vee One Suite 0.5.1 - One second official beta release!

by Rui Nuno Capela

Howdy, The gang-of-three aka. the Vee One Suite of old-school soft(ware)-instruments, featuring synthv1 [1], a polyphonic synthesizer, samplv1 [2], a polyphonic sampler and drumkv1 [3], as a drum-kit sampler, are once again released in beta phase though. The changes for this one second beta release are the following: - Fixed LV2 plugin relative/absolute file path state resolution. (drumkv1 [3] only). - One decimal digit added to all scalar parameters and knobs. - Stand-alone JACK client ports outrageously renamed from a zero based numbering scheme into a plus one natural one. - Experimental LV2 Time/position atom-event support (Delay BPM). Please, don't hesitate to ask whether any of the above esoteric babbles doesn't get you on to update as soon as you can. One special note goes for all the users out there of drumkv1 [3] LV2 genre: the update is not just interesting but a must, seriously ;). As usual, all is available in dual form: - a pure stand-alone JACK [4] client with JACK-session, NSM [5] (Non Session management) and both JACK MIDI and ALSA [6] MIDI input support; - a LV2 [7] instrument plug-in. The Vee One Suite are free and open-source Linux Audio software, distributed under the terms of the GNU General Public License (GPL) [8] version 2 or later. The gore details are as follows ;) * synthv1 - an old-school polyphonic synthesizer [1] * synthv1 0.5.1 (second official beta) is out! synthv1 is an old-school all-digital 4-oscillator subtractive polyphonic synthesizer with stereo fx.

A Gentle Introduction to SuperCollider

by Bruno Ruviaro

Hi all, I would like to share with everyone this new SuperCollider tutorial I wrote over the Summer. It's specifically written for total beginners, and it's Creative Commons licensed, so feel free to share, copy, distribute, remix...: PDF: https://ccrma.stanford.edu/~ruviaro/temp/00_PDF_A_Gentle_Introduction_To_Su… Source files (LaTeX): https://github.com/brunoruviaro/A_Gentle_Introduction_To_SuperCollider ... and in case you'd like a nicely printed copy at cost value: http://www.lulu.com/shop/bruno-ruviaro/a-gentle-introduction-to-supercollid… The title is a little homage to Touretzky's Common Lisp book, which I loved when I read it years ago. This tutorial is also very much indebted to David Cottle's intro chapter on the SuperCollider book. I consider this tutorial to be in "beta version" -- I'll try it for the first time in a classroom situation this Fall, and probably will change things over time. So I very much welcome feedback from anyone who cares to read it! Best, Bruno

html5 audio through jack

by Iain Mott

Hi list, I'm thinking of updating some of my web pages to use multi-platform flash/html5 audio players, at present they use flash only and won't play on iPads for example. Due to some problems I was having with pulse audio in relation to my HDSP interface I have recently disabled it and all my audio is running via jack/alsa and the HDSP interface. With flash in firefox, there are no problems and the audio plays. My .asoundrc is configured with the following: pcm.rawjack { type jack playback_ports { 0 system:playback_1 1 system:playback_2 } capture_ports { 0 system:capture_1 1 system:capture_2 } } pcm.jack { type plug slave { pcm "rawjack" } hint { description "JACK Audio Connection Kit" } } pcm.!default { type plug slave { pcm "rawjack" } } HTML5 players in firefox don't play however via jack. When pulse was enabled, HTML5 content would play through the computer's built-in sound card. Now that it's disabled I can't get it to play through jack. An example page with a HTML5 player is here: http://www.html5tutorial.info/html5-audio.php Any suggestions please? A modification of the .asoundrc? I'm running Ubuntu 14.04 Thanks,
