granular music recommendations?
by AlgoMantra 23 Jul '24

23 Jul '24

Yo All....I'm trying to download and study some of the best music out there which features granular synthesis. I haven't heard much yet beyond Iannis Xenakis, but I'd love to know what your favorites are. Perhaps it would be worthwhile putting up a torrent of the same. If possible, kindly provide links to mp3 files or any other type of free downloads. (What do you think of Jaron Lanier's music?) http://www.jaronlanier.com/musicdownload.html cheers! ------- -.- 1/f ))) --. ------- ... http://www.algomantra.com

Hi Mike and others, Thanks again for your advice. I’ve read through the documentation, and I think I understand it for the most part. I had luck with taking my data, converting it to a tab delimited file and printing it to ChucK. I’ve converted the data entries to a string, but I can’t convert the values to an array. Am I just overlooking something simple? Thanks!

That will disintermediate the entire process and remove the need for using Open Sound Control to send the data into Chuck. UNLESS, you mean to generate this data in realtime with Matlab and sonify it using Chuck, in which case, you should definitely use Open Sound Control to send the values to your Chuck script as they are generated. (The relevant Chuck examples will be found the folder called "osc". Those should tell you how to send and receive OSC messages.) Also, if you're sending OSC from one local program to another on the same machine, you'll probably not have to change anything with regard to your firewall. On the other hand, if you're sending from one machine to another, then you might want to disable the firewall altogether in order to test the connection. Once you get it operating, then you should probably put the firewall back on and change the settings to allow connectivity through only the ports you're using. Hope that helps! Good luck!

Matlab data help

27 Jun '12

Hi guys, Thank you so much for your advice! I hadn’t realized the meaning of OSC, so I really appreciate you bringing this to my attention. I’m still a novice at programming, so I might need some time to digest the codes and examples. I’m still a bit confused about how to plug OSC outputs from Matlab into Chuck. I understand that I could eventually save the OSC values in a variable, but would I need to use UDP and take down my firewall? As was suggested, I’ve attached one of the data sets I’m working with. It’s a csv with some 3,000 data points representing the stress-strain diagram for aluminum. I’m hoping to put the values in the left column (strain) in a time array and the values in the right column (stress) in a frequency array. These values were converted from matlab.

Jordan's got the right idea, I think. Also, OSC is great for this kind of thing. Check out pyliblo OSC library for python. python's great at data manipulation.

Importing Data/Using Quadraphonic Headphones with ChucK
by Hayden Dahmm 23 Jun '12

23 Jun '12

Hi everyone, My name is Hayden, and I’m a blind student at Swarthmore College, where I intend to major in Environmental Engineering. Over the summer, I’m working on learning ChucK so I can create auditory data displays. I’ve made decent progress so far, but I do have a couple questions. I’m struggling to import data from cmv or .m files, forcing me to enter values in by hand. Does anyone have suggestions as to how I could circumvent this problem? Also, I plan to use a pair of quadraphonic headphones to interrogate spatial data with a joystick or track pad. Has anybody tried using ChucK for this purpose before? If so, I would be very interested to hear your thoughts. Thanks so much, Hayden hwdahmm(a)live.com

Hi Chris. Yikes, anything above about 40% CPU is pretty dicey for live audio. The OSC listeners themselves should be fairly trivial, CPU-wise. I suspect that the bulk of your power is going to calculating audio, so that's where you should look to optimize. Do you have 26 simultaneous voices sounding? If so, that might be too taxing for ChucK (or any other live audio language, for that matter). But if any of the voices are only occasionally active, I suggest unchucking UGens when they're not in use (myOsc =< dac etc.) Any UGens not directly connected in a signal path to either the dac or the blackhole will not calculate audio, thus preserving precious CPU cycles. You can reconnect them on demand. -Joel >This program takes up a LOT of CPU resources, and I was wondering if anybody had any >tips on optimization, or if this is just a fact of life with a ChucK program of this >nature.

is there a way of doing "callbacks" ( i.e. passing function as argument to be called later ) ?

This is a question Chris did to me and it reminded me some related questions i forgot to ask: Is there a type "function" or type "Class" ? Is there anyway for "evaluating" a string to chuck code in order to do dynamic calls ( like javascript "eval" function for instance ) ?

question about memory optimization
by [chriswicks] 07 Jun '12

Hello all! I have a moderately-sized project that I'm working on right now...the basic gist is that it's several smaller ChucK programs containing infinite loops and OSC event "listeners" that trigger certain behaviors or events in the music all running concurrently (the main catcher/sender for the OSC values is being written in C++). All told, in its present state there are 26 shreds running in the VM. This program takes up a LOT of CPU resources, and I was wondering if anybody had any tips on optimization, or if this is just a fact of life with a ChucK program of this nature. I know that the OSC stuff has only recently been implemented. I feel like I've been reasonably efficient with my code, but I'm seeing upwards of 80% CPU usage. It stays pretty stable, but this seems like a lot. In its current state, it's unplayable on my dual-core laptop, but my quad-core desktop can handle it OK. Thanks for any insight! -chris wicks
