Efficient analysis & resynthesis for game audio
by S. Elliot Perez 01 May '20

01 May '20

Hello! I've been using Pure Data and the Heavy compiler (hvcc) to make procedural audio for games/interactive media pieces the last couple of years. I just started going through the videos of the Kadenze course. The first couple of lessons, I did what Mr. Cook was doing in his ChucK software using Pure Data... but then I got to Session 3 where he showcases a method of resynthesis using two scripts- one to analyze a sound file and output a list of peaks (frequency and amplitude), and one to perform the resynthesis. I was very impressed with how quickly this goes as you can just copy and paste the list from the 1st list into the 2nd one and you already have a working model which you can then begin to tweak. With Pure Data, this would be an exponentially more arduous process of manually looking at a spectral analysis, filling out boxes, connecting them with wires, copying & pasting for each frequency... I'm curious as to what the possibilities of integrating these ChucK algorithms into standard programming languages like C++/C# for use in game engines. On the download page of ChuCK it says that the newest versions are made to be embedded in other systems. Is there documentation detailing this somewhere? -- *Ｓ・エリオット・ペレスwww.selliotp.com <http://www.selliotp.com>*Sound Designer for * enenインタラクティブサウンドディザイン* [image: http://enengame.com/] <https://youtu.be/xYpc9agfil8> *「エンエン」は日本のAppStoreでリリースされました！* [image: https://itunes.apple.com/us/app/enen/id1164297889?ls=1&mt=8] <https://itunes.apple.com/us/app/enen/id1164297889?ls=1&mt=8>

chuck hoarding the soundcard
by Geoff Little 28 Apr '20

28 Apr '20

Hi chuck-users, Not sure if this mailing list is still in use but I've signed up for the chuck course on kadenze and am having issues after installing chuck. I'm on Debian bullseye which is the current (as of April 2020) testing release. I've git clone'd the chuck repo and make'd and make install'd. I tried both `make linux-pulse` and `make linux-alsa`. My version of chuck is 1.4.0.1. I'm able to run ck files through `chuck` and hear output as expected, for example echo " SinOsc s => dac; 0.6 => s.gain; 220 => s.freq; 1::second => now; " | chuck /dev/fd/0 plays the expected sound and exits cleanly. However, if I'm watching a tutorial video on kadenze or youtube (in firefox if that matters), I get unexpected results when I run the above command. I see [chuck]: RtApiAlsa::getDeviceInfo: snd_pcm_open error for device (hw:0,0), Device or resource busy. Similarly if I run `speaker-test`--while this is running and making noise, `chuck` spits out the same resource busy error. However, if I run `speaker-test` and play a youtube video, it works as expected, the speaker-test noise and youtube noise mix and play at the same time. Interestingly, if I run `chuck` with nothing else and get the expected sound and soon after start `speaker-test`, `speaker-test` will wait / not start until `chuck` exists, suggesting that chuck somehow "hoards" the soundcard so that other sound-producing apps can't get access and mix-in. Does anyone know how to resolve this issue? I believe (I'm not 100% sure as I'm not very familiar with sound hardware and software) I have both alsa and pulseaudio? This is why I tried make'ing with both. I'm not sure how they interact. Thanks and hope everyone is staying safe and home, Geoff

Hi, I just got my Bela board, and I was wondering if anybody has done anything with ChucK on it. I found this https://forum.bela.io/d/117-chuck so it seems somebody could have done something. Cheers, Mario

This is truly odd. I don’t have easy means to test it. I don’t know why it wouldbe broken dependent on the dac, however. For fun you might try something like this, just to verify that the valueAt() function is what’s busted.

sndBuf.valueAt
by Forrest Curo 19 Apr '20

19 Apr '20

Using chuck linux-jack this gives me reasonable numbers between -1 and 1. Using chuck linux-alsa I'm able to play the file I've read into sndBuf; but trying to copy it via .valueAt gives absurdly high ["out of range"] numbers at each point. [It can be a different high number different times I run chuck, but the number it is turns up at every point I sample.] Is there a fix for this? Aside from using jack on a computer where it befnurgles the midi?

memory usage
by Mario Buoninfante 16 Apr '20

16 Apr '20

Hi, I was trying to better understand how ChucK deals with memory management. I know there's no garbage collector in place and I also checked on the mailing list, where I found several really interesting conversations about this topic. But still, I've got this scenario where the memory in use keeps growing.: >From terminal I launch: chuck --loop then I run several times: chuck + gc_empty.ck every time I wait that this ends first. gc_empty.ck contains just 1 line: 1::second => now; at the same time I'm monitoring chuck using top (on MacOS High Sierra 10.13.1) and I get the following values for MEMORY: as soon as I launch ChucK: 9008K 1st time I run "gc_empty.ck": 9108K 2nd time I run "gc_empty.ck": 9112K 3rd time I run "gc_empty.ck": 9196K Why is ChucK using more and more memory? Sorry if this is maybe a silly question. Cheers, Mario

Hi Spencer, Amazing, I'll have a look at the links you shared, it's good to have a starting point :) thanks. About the Chugins I'll make a PR then, I think that due to their simplicity and general-purpose nature, it could be useful to have them in the Chugin repo.

Oscillosope UI
by Mario Buoninfante 15 Apr '20

Hi, Recently I've been poking around with Chugins and created a couple of things I thought were 'missing' in the official ChucK and Chugin repos, UGens like Wrap, Clip, Sample and Hold, etc. ( https://github.com/mariobuoninfante/ChucK_chugins), and I was thinking about adding an oscilloscope as well. Recently I also put together a clunky class that allows you to plot things using gnuplot, but it's an offline thing, then you need to use Std.system() (that means using --caution-to-the-wind), I mean it's not ideal to be honest, especially if you're looking for an oscilloscope. I was wondering, would a Chugin be the right thing to work on to create an oscilloscope? I never dealt with UIs before, so I could be saying something completely naive here, but I was thinking about having a Chugin you can connect UGens to then display their waveform. Then have methods that allow to change the oscilloscope settings (ie x-axis and y-axis resolution, etc.). Does anybody have any experience with this kind of things? Chugins with UIs? Is it even sensible? Cheers, Mario

Re: [chuck-users] Chugin for UI (oscilloscope)
by Perry R. Cook 15 Apr '20

Well, MAUI is a chugin, only for Mac, so there is precedent for UI in Chugin. MAUI is currently broken in the command line, only working in MiniAudicle. Perhaps Spencer/Ge can chime in on the vagaries of doing UI/graphics via Chugin??
