I love it! I really like how it feels like you're in the room with them. I did a spectrum analysis on it and noticed that there was a big hump at about 100 Hz... so I messed around with it for a bit. Here's what I did: EQ: reduced 100Hz (1.0 octave bandwidth) -16dB Compress: 2:1 with a threshold of -20dB Normalize Here's the result: http://www.banjoboy.ms11.net/music/at_slum_avenue2.ogg I don't know if that's closer or farther from what you were looking for, but that's my attempt at helping... ;-) -TimH

[linux-audio-user] Verrrrry slow network using 2.6.16-rt

by Frank Barknecht

Hallo, (this is a repost without the attached and rejected configs, sorry for dupes) I'm currently testing Ingo Molnar's RT patches and I see strange things happen to my network, when running a patched kernel. I use the patch-2.6.16-rt12 currently (just saw, that patch-2.6.16-rt13 is out as well, but I cannot rebuilt the next days). The symptoms are very slow connections through a pppoe network connection. Logged in with ssh remotely sometimes stalls for dozens of seconds, then it comes back for some seconds, then it stalls again and no keyboard input is possible. Other network stuff also is very slow, for example downloading the normally *very* fast Ubuntu-bittorrents takes ages and I don't get the good download rates I'm used to get from these fast torrents. Booting a vanilla 2.6.16 kernel gives the good network connection I'm used to. I don't see anything suspicious in log files. Playing network sessions with remote musicians is impossible with the rt-patches currently for me, so I'd like to fix this somehow. Did someone else see similar stuff happen with Ingo's patches or some of them? Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__

[linux-audio-user] NEW MUZIK RELEASED / about LMMS

by perlanegra proyect

Hey !! another post here... This time I've been investigating on the hip hop production and on related software ( free and commercial software ), and I've done a pair of things with some very famous and... ehem !!!! ... not so legal software and I've done a pair of hip hop productions 4 turntablists. The themes are released here: http://www.archive.org/details/Riding_the_Sunrise_Proyect_by_PerlssDj I hope u like it... It's not made with free software, but it's done with free samples, so u can check it. My investigations on the linux sound are not so fast, sorry... I'm a linux user with not many experience, but I think that can change... and another thing... I'd like to know if anybody can tell me if I can find a Debian repository with the LMMS ( Linux Multimedia Studio ) packages because it's terrible try to install all the sources manually ( it's very a bored work 4 me ), if somebody can help me, please do it.. thanks B happy... and remember that any kind of comment is good.. -- ... visit always http://perlssdj.blogspot.com 4 cool stuff !!...

[linux-audio-user] Re: regarding the 2nd Book Of Linux Music & Sound

by Juhana Sadeharju

>From: Dave Phillips <dlphillips(a)woh.rr.com> > >wasn't the true reward anyway, so perhaps there's a way to turn it into >a community-based work. Making it freely available would be a good idea. Something which can be modified later when all software evolves. More so if it is only publisher getting all the money. With consequence that the book is not read by people who we wish to read it. When a book is freely available, people may browse it just because they are curious. Are you able to place the text available with a free license? If we have to start from the scratch, then that should not be a problem. Juhana -- http://music.columbia.edu/mailman/listinfo/linux-graphics-dev for developers of open source graphics software

[linux-audio-user] In search of jack-enabled visualization app

by Ken Schutte

Hi, I'd like to find something that can take arbitrary jack inputs and do some real-time visualization. Preferably, show some spectral analysis and can display full screen. I'm thinking of trying to put something together myself, but it would be very helpful to at least find something to look at for a place to start. Does something like this exist? thanks, Ken

I can't agree with this. The most popular high quality music distribution format is still the audio CD, and most sample libraries etc are still at 44.1, so it makes sense to work at 44.1 and avoid having to src everthing. On consumer hardware the slightly extended top end makes little difference too. I can understand why compatability with cheap fixed 48k rate soundcards is useful, but I don't see that as a reason to make everything default to that rate. The only place I see 48k used is for people working with video. By the way, does anyone know how I can get my email replies to go to to the correct place in a thread in the archives? They always appear as a new post, rather than after the message I am replying to. I get the digest version and just copy and paste the subject line, there must be something I'm missing. > > > and problem is solved. > > > That's interesting, I did not know snd-ens1371 was affected.

[linux-audio-user] magic mastering tips needed

by Chris McCormick

Atte, I really like this track. Some have complained about the tuning of instruments, but to my ears this just sounds authentic and adds character. I think it's perfect as is. Where can I get some more? Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx

Hi Brian, > Chris that track is genious. i haven't liked any lau stuff this much > since f4. it's got that autechre like computer-made-it-up feel. how > did you do the sequencing? also within pd? I'm starting to play with pd If it has a computer-made-it-up feel to it then that is logical because some elements of the song are randomly or algorithmically generated. With regards to sequencing; in the past I have used custom built sequencer patches (see below) but this was the first track on which I used a TR-505's <http://en.wikipedia.org/wiki/TR-505> midi capabilities to sequence the track. The TR-505 specifies the order in which pieces of the breakbeat and other drum sounds are played, and specifies on which beats in a bar to play melodic notes. The computer randomly picks the melodies from a set of notes which I choose that 'go together'. All of the effects are controlled using a u33 midi controller, and a small midi controller looping patch is used to make sure i don't have to move all the knobs all of the time - they move themselves in a repeating fashion if i turn the knob to 127. To make beats more interesting I often employ an algorithm that randomly shuffles back and forwards the position that a loop is playing at, at the end of a bar or set of bars. In this case I assigned that shuffler to a knob on the uc33 so I had control over when the beat went wobbly. > myself and this track has really got me inspired to dig on in. could > you maybe share some of the patches you used? For sure. I am working on a new modular synthesis system which is very specific to my midi setup (uc33 and TR-505) but I haven't put this in CVS yet. However, the building blocks and effects from which much of my music is created can be found in the cvs repository here: http://mccormick.cx/viewcvs/s-abstractions/ There is currently no license specified on these patches, but you can assume that they are public domain. I'll probably stick an LGPL license or similar in there shortly. If you want to write stuff using Pd without too much hassle, probably a good place to look is Frank's collection of RRADical abstractions, which are of a much higher quality than mine, though I think they often have dependencies outside of Miller's puredata: http://footils.org/cms/show/1 If you look up Han's Extended Installer then that should satisfy any dependencies of the RRADical abstractions. > once again, thanks for sharing such an awesome work. Thank you very much for your interest and your compliments! An inflated ego is a great inspiration to write more music. Best, Chris. ------------------- chris(a)mccormick.cx http://mccormick.cx
