I want to build qtractor 0.4.7 with vst hosting capabilities so following the instructions in the README.VST text file I downloaded the vst include files, placed them at root in '/usr/include/' and proceeded to build qtractor 0.4.7 on Ubuntu 10.10 by the way, I'm using the 2.6.35-24-generic kernel (since it works with broadcom drivers) the './configure' got as far as looking for the jack libs (which I do have installed and am using on a daily basis) and failed here is the error message from './configure': 'checking for main in -ljack... no configure: error: JACK library not found.' is there something in the jack lib that wasn't installed or is there a path I need to fix somewhere? any help is appreciated!

OT: isolating transformers, redux

by Ken Restivo

I've been looking around for a 1:1 line level transformer to lift the ground when connecting the headphone stereo output jack of a laptop or iPod to a consumer-grade amp that takes a headphone jack input. All I've been able to find is insanely expensive, like US$200. http://www.jensen-transformers.com/prices.html#ci2rr That's ridiculous. I just need the transformer itself; I can connectorize it myself. But my searches (Jameco, Mouser, DigiKey) aren't turning up anything except POWER transformers, much larger than what I need. Can anyone point me to some part numbers and (reasonable) prices for a 1:1 line level transformer? Thanks. -ken

OT: Parma construction

by Ken Restivo

I think the LAC conference was in Parma a year or so ago, well here's a documentary (in Italiano) about the construction taking over the area: http://youtube.com/watch?v=Z3u7y-SN2O0 Weird. The scenes in this film look to me like Marin and Sonoma counties: generic office parks lining the highways, with vineyards and cattle grazing off in the distance. -ken

Compiling Aube

by Louigi Verona

Guys, did anyone try to compile this rather old but intriguing piece of software? http://www.metadecks.org/software/aube/ For me it says it needs gtk and although I have both gtk1.2 and gtk2 dev packages installed, it is still not happy. -- Louigi Verona http://www.louigiverona.ru/

USB ISO Read and write

by Basavaraj Hiremath

Hi,I have implemented/ported USB device driver on the custom platform(ARM processor).I am trying to read and write audio data through to USB headphone.These are my questions? 1) USB isochronous read is an asynchronous call, how can I read data from the mic and send immediatly to speaker(just to make echo), 2) How much data needs to be read from the mic and send to speaker without loosing audio quality?(is it every frames (1msec data) or more buffering can be done) Basically, how can I read from mic and send to speaker continuously without loosing data? Thanks in advance for your answers.Raj Basavaraj Hiremath

New medieval/darkly moody mellotron music

by Julien Claassen

Hello all! So it's christmas and the tradition is to distribute presents. :-) I'm doing just yet. Only with presents, you never know, if the receiver likes them. :-) I don't know how to really classify that piece. As a genre I tentatively chose "Celtic". It might have some celtic elements, but I think it's just generally a little medieval. The rest is made up by moody, dark ideas and a bit of 70s charm. This piece is done using only one sample library of tron sounds. They are free sounds, provided by Taijiguy, the library in this format is not released yet and so I'll keep that, until it is. I'm sort of a beta-tester. So to the magnanimous maker of this library: A BIG THANKS! It's wonderful, absolute fun to play with. Here's the music: http://juliencoder.de/nama/dream_of_the_old_land.ogg And as usual for the oldfashioned: http://juliencoder.de/nama/dream_of_the_old_land.mp3 Or access it from the website: http://juliencoder.de/nama/music.html I used minimal processing on that: Just a reverb with jconvolver and a bit of stereo panorama distribution. I hope you enjoy it and as ever feedback is always welcome. :-) Warmly yours Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de

partition table

by rosea.grammostola

Hi, Do you have a special /home partition? Why or why not? Will performance be better if you have a special partition for audio? Thanks in advance, \r

Finally got time to play!

by Folderol

I've been continuing to work on my guitar playing as and when I get time, and here is my latest effort based on the same chord progression as I used when collaborating with a friend for 'Wandering'. I'm quite proud of the fact I was able to play this right through with only a couple of edits. Hope you like it. http://www.musically.me.uk/music/Wandering_Again.ogg Guitar recorded with Timemachine Synth is Yoshimi Guitar effects from Rackarak Sequencer is Rosegarden Final tidy up in Audacity -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune. Exchange them and we can both have a poem, a tune, and a song.

Batch conversion from Apple AAC to mp3?

by Mark Knecht

Hi, I've got a 10,000 iTunes library in AAC format. I'd like to create a copy of it in mp3 preserving the directory structure of the original but in a different location. Can I do this in something like sox or some other program? If so how? Thanks, Mark
