Audio Scrubbing???
by Brutus Gates 20 May '10

20 May '10

Hi, I don't think "audio scrubbing" is the correct technical term for what I want to do... Maybe someone can suggest a better term? Here's what I want to do: I want to be able to move through a sound file along the time (or sample) "axis" while maintaining the pitch of the original. Here's how I think I would do it: The rate at which I am "scrubbing" through the sound file (using a wacom tablet for example) would be mySampleRate. I would then pitch shift by a factor of: originalSampleRate/mySampleRate Of course the devil is in the details... If anyone has a link to math or code that could help me that would be great... Or better yet, maybe Chuck has some UGens that can make this easier... B

chuck vs. fc13/gcc4.4.4 => patch
by Fernando Lopez-Lezcano 19 May '10

The attached patch makes it possible to build 1.2.1.3 on top of fc13 + gcc4.4.4, I imagine other new systems will benefit. -- Fernando

Re: [chuck-users] chuck for live performance - latency
by Jacob Doran 19 May '10

19 May '10

Great responses, all very encouraging and exciting! So I installed chuck on my Windows desktop in the form of MiniAudicle and have been running the examples. All seems good apart from one issue which I had a feeling would crop up, latency. The lowest I can set the buffer size to with it still working is 64. I have a Saffire LE sound card which should be pretty good but the latency in Chuck is too great for it to be useful in a live context. So I have a few more questions: - Should I be using Linux? Is the latency better in Linux then in Windows? If so what flavour of Linux would people recommend. - Should I be trying to build chuck for ASIO, I have seen some builds for this in the forums, but not for the latest version. - Are there any other tips or tricks for reducing the latency? Thanks again for all your help.

chuck for live performance
by Jacob Doran 18 May '10

Hey Chuck Users, I'm a computer programmer, guitarist and singer who lives in London. Recently I have moved away from pure acoustic performances and have been using boss loop pedal and effects in gigs which has been fantastic but I'm already finding limitations. Then I had the idea that I might be able merge my programming skills with my music and program my own loop pedal rig using ChuCK software and a midi foot controller. It would be able to loop my guitar and voice multiple times live (like traditional loop pedals), turn loops on and off, and also apply real time manipulation, ping pong delays, pitch shifting, algorithmic harmonizations and who knows what else. I would control this all with a midi foot controller and a laptop while I play and sing. I was wondering if anyone has tried doing this type of thing before? A lot of what I have read seams to be more about virtual synthesis rather than real time audio manipulation/looping in a live performance? Is this something ChuCK could do well? What about performance, stability, or latency? I'm going to download ChuCK and play around to try and find these answers myself soon but any useful pointers and suggestions would be most appreciated. Thanks in advance for your help, Jacob http://myspace.com/jacobdoran/

Works

Hello Love the idea of ChucK and computer aided composition (call it what you will) is intriguing. I am new to this area and I'd love to hear/see anything that's being produced by ChucK users. I don't mean a page of code that produces one noise but full pieces of music/sound design etc.... A group of people produced a CD using Supercollider which worked well and was inspiring. Is there anything out there like this? I've looked through the tutorials/examples and there are a few things in there but would like to hear things produced by users? Cheers James

osx vs. chuck vs. jackrouter
by Fernando Lopez-Lezcano 07 May '10

07 May '10

Hi chuckers (chuckists?)... anyone out there with experience in the combination outlined in the subject line? ChucK is not really happy running on top of jack - under osx using jackrouter, see link below. The best we could do with Michael this afternoon (cc'ed) is to get chuck running with 2 output channels and that took some parameter tweaking. Selecting more channels would make chuck die with an error message (this is from the command line, sorry, I don't have the messages, Michael: could you post them and the command line arguments we used?) In case somebody wants to test: http://www.jackosx.com/ (we used version 0.86 which has support for netjack netone which is what we would be most interested in using). Thanks for any help... -- Fernando

Is ChucK still developped ?
by Thomas Girod 06 May '10

06 May '10

Hi there. I'm currently making a small app using ChucK, and I find this language marvelous - truly, I find it much easier to get things done with ChucK than with SuperCollider. But at the same time, it's pretty obvious that the language still have a few caveats, stuff that is not implemented yet. Looking at the dev list, I can see there isn't much activity around this project anymore. So, is the project dying ? T
