It is playing backward from 0, to 0, so it does nothing. You have to set .pos to .samples() (point to the end, so it can play backward). In the example, you’d need to advance time to let it play forward: mySndBuf.samples() :: samp => now; // you’d hear it play forward then set rate to -1, then advance time again to hear it backward. PRC Looking at our book, I see that you didn’t copy all the lines. You’ve got to advance time to hear anything in ChucK. // 4.3 Playing sounds in reverse // by ChucK Programmer 4102, yluJ #A SndBuf mySound => dac; me.dir()+"/audio/hihat_04.wav" => mySound.read; #1 mySound.samples() => int numSamples; #2 // play sound once forward 0 => mySound.pos; numSamples :: samp => now; #3 // and once backward numSamples => mySound.pos; #4 -1.0 => mySound.rate; #5 numSamples :: samp => now; > On Feb 12, 2020, at 1:30 PM, chuck-users-request(a)lists.cs.princeton.edu wrote: > > Send chuck-users mailing list submissions to > chuck-users(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck-users > or, via email, send a message with subject or body 'help' to > chuck-users-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-users-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck-users digest..." > > > Today's Topics: > > 1.

Re: [chuck-users] playing SndBuf backward

In my experience, in SndBuf, to play the file backwards from the end requires file.samples() - 1 => file.pos; file.rate(-1.); If the size of the file is, for example, 1000 samples, the first sample is located at 0 and the last sample bit is 999 (not 1000). On my machine, at least, if I set the position beyond the end of the file, it won't play backward. However, when using LiSa, the starting position is 1::samp, and the ending point is 1000::samp davd David Loberg Code School of Music Western Michigan University Sorry PRC it doesn't work: When i set "buf.rate" to 1.0 and "buf.pos" to 0, it does but not the other way around.... me.sourceDir() + "aeiou.wav" => string filename; if( me.args() ) me.arg(0) => filename; SndBuf buf => dac; filename => buf.read; buf.length() => dur totalelengte; buf.samples() => int samples; samples => buf.pos; -1.0 => buf.rate; samples::ms => now; ________________________________ Van: chuck-users-bounces(a)lists.cs.princeton.edu<mailto:chuck-users-bounces@lists.cs.princeton.edu> <chuck-users-bounces(a)lists.cs.princeton.edu<mailto:chuck-users-bounces@lists.cs.princeton.edu>> namens Perry Cook <prc(a)cs.princeton.edu<mailto:prc@cs.princeton.edu>> Verzonden: woensdag 12 februari 2020 20:58<x-apple-data-detectors://3> Aan: chuck-users(a)lists.cs.princeton.edu<mailto:chuck-users@lists.cs.princeton.edu><chuck-users(a)lists.cs.princeton.edu<mailto:chuck-users@lists.cs.princeton.edu>> Onderwerp: Re: [chuck-users] playing SndBuf backward You can set the .pos to wherever you like, and set the .rate to a negative number.

=> now
by herman verbaeten 11 Feb '20

Hi, I'm trying to understand what's really happening in chuck. I thought i did untill i saw some exemples of midi. Normaly you can only feed time or duration into now ( e.g. 10::ms => now) But in case you are awaiting a midi-in message you write : MidiIn min; while (true) { min => now } So in fact do you assign the message to time? Total confusion! Thanks for your answer. Herman

ADSR and gradually shift pan from left to right and back
by herman verbaeten 06 Feb '20

06 Feb '20

Hello , Thanks a lot for your help. I still have some general questions and some about the program that follows: 1. Where can i find a chuck editor with the possibility to find words and replace them (all) and that also gives the colors for reserved words etc. 2. Is there a way to debug line per line to discover logical errors? 3. i discovered by accident that sometimes i can use "p.puf" but on other occasions i have to write "p.buf()" why is this? 4. in the program hereby, is there a way to have the pan do it's job independantely from the note-envelope-flow? to go faster or slower? 5. When i run this program it does what i want but i can't figure out why it says 2 times "p.pan = 1.000000" and 2 times "p.pan= -1.000000" (see below) Thanks !!

Re: [chuck-users] Multichannel Mono Output using ChucK (Matthew.Noone)
by Perry Cook 31 Jan '20

31 Jan '20

The trick here is you also have to tell ChucK to be 4 channels. From the command line: chuck -c8 YourFile.ck depending on what your —probe shows, you might even have to specify which dac (and adc) to use, especially if they’re different device numbers or channel numbers. Also, might need to up the buffer size to avoid clicking, especially for lots of channels. Examp: chuck -c8 -bufsize2048 -in2 --dac1 --adc0 YourFile.ck Hope this helps, PRC PS: If you’re using MiniAudicle, then you need to do some menu stuff to pick output/input devices, and numchannels as well. > On Jan 30, 2020, at 8:02 AM, chuck-users-request(a)lists.cs.princeton.edu wrote: > > Send chuck-users mailing list submissions to > chuck-users(a)lists.cs.princeton.edu > > To subscribe or unsubscribe via the World Wide Web, visit > https://lists.cs.princeton.edu/mailman/listinfo/chuck-users > or, via email, send a message with subject or body 'help' to > chuck-users-request(a)lists.cs.princeton.edu > > You can reach the person managing the list at > chuck-users-owner(a)lists.cs.princeton.edu > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of chuck-users digest..." > > > Today's Topics: > > 1.

Classes to effectively use FluidSynth microtonally in ChucK
by Forrest Cahoon 30 Jan '20

30 Jan '20

Some time ago, I extended the FluidSynth chugin with hooks into libfluidsynth's tuning API. Once I started working with some more sophisticated soundfonts (such as those at https://sites.google.com/site/soundfonts4u/) I found a problem: it turns out that, the way libfluidsynth tuning works, the sample for the assigned-to note number is retuned to the pitch to which it is assigned, instead of using a sample which meant to be close to the desired pitch. So I wrote a set of ChucK classes so that I could just specify the note I want and let ChucK decide which MIDI note number to assign it to. If this is possibly of interest to you, check out my code at https://github.com/forrcaho/ChucK-code/tree/master/fluidsynth .

We also added Std.ftoi(x) to the language a while back (at 1.3.2.0). It’s much clearer to read, and more obvious as to what’s going on and why, than the casting notation. To round, just add 0.5 to x in the function arg. so: > Std.ftoi(0.4*myBuf.samples()+0.5) => myBuf.pos; would set your play pointer to the 40% point in the sound buffer. Prc Sent from my iPhone > 1.

Conversion float to int using SndBuf
by Mícheál Ó Catháin 21 Jan '20

21 Jan '20

Hi What is the best way to convert a float to int in the following please? //I want to set myBuf.pos to a percentage of myBuf.samples()... //Start playing at say 40% through the total number of samples. 40.0 => float pctPosInit; pctPosInit/100*myBuf.samples() => myBuf.pos; This throws the error argument types don't match. I'm not seeing how to convert the float to an int here. Thanks for your help! Micheal

Array of SndBufs at different rates
by Matthew.Noone 10 Jan '20

10 Jan '20

Hi all, I'm trying to figure out the easiest way to setup an array of the same SndBuf playing at different rates. I'm using a Gong sample. Playing that back at different rates to make basic melodic patterns. I can make a random function but I don't know who I can set an array of rates which I can then randomise. Any ideas? Here is my existing code with random function. (I tried writing an array at the start but not sure how to call that?) Sorry for such an easy question... MJ //Sndbuf //4 => int gongs; //[.25, 0.5, 1.0, .25] @=> float rates[];//array of possible rates (changing will change harmony) //program SndBuf mySound => Delay d => JCRev rev => Gain g => dac; 0.8 => rev.mix; //delay and rev setup d => Gain feedback => d; while (true) { .02 => g.gain; me.dir()+"Samples/MotherGong.wav" =>mySound.read; 0 =>mySound.pos; Math.random2f ( 20.1, 22.01 ) => mySound.rate; Math.random2f( 0.3, 0.5) ::second => d.max; Math.random2( 30, 70) ::ms =>d.delay; Math.random2f( 0.3, .8) => feedback.gain; 0.50 ::second => now; } Dr. Matthew James Noone Sarode Artist & Irish Research Council Postdoctoral Fellow Irish World Academy of Music and Dance University of Limerick

Re: [chuck-users] MultiTap delay
by Perry Cook 08 Jan '20

08 Jan '20

The parallel multi-delay and multi-tap single delay line are identical in function. Delays are linear so they can be factored any way you like and as long as the impulse response is the same, it’s a duck. I use the multi delay version myself. Wastes memory, but who cares.

multi-tap delay vs multi-delay
by Michael Heuer 07 Jan '20

07 Jan '20

Hello, Does anyone have an implementation of a multi-tap delay in ChucK? I use what may better be called a multi-delay, where all multiple delays with different delay lengths are arranged in parallel /* inlet --> _pre --> _echo1 --> _post --> _boost --> wet ^ | ^ | | | | | | +----> _echo2 ----+ | | | | | | +----> _echo3 ----+ | | | | | | +----> _echo4 ----+ | | | +------- feedback -----+ */ I can't get my head around it exactly, but it feels like this is different than a true multi-tap delay, where one has a loop of the longest delay time and then multiple taps within that delay time. I've been wanting lately to do something similar to these "Volante takes this into account with a Spacing control that’s adjustable between Even, Triplet, Golden Ratio (for dense, non-overlapping echoes), and Silver Ratio (for non-overlapping repeats biased toward the quarter note). And the Spacing control is continuously variable, allowing you to morph between its settings in real time." and "3.3.3 Taps The number of delay taps, from 1 to 64. The Taps control affects the Tap Delay Block in the signal flow diagram. … 3.3.5 Spread The rhythmic spacing of the Taps. More negative values will group taps towards the beginning, for a ”slowing-down” feeling. More positive values will group taps towards the end for a ”speeding-up” delay sound. Specifically, a 0 value will result in constant spacing, while values between 0 and +/- 50 have linearly increasing/decreasing tap spacing, and values between +/- 51 and +/- 100 have exponentially increasing/decreasing tap spacing. The Spread control affects the Tap Delay Block in the signal flow diagram." Thanks in advance! michael

WAV playback gets louder with each iteration
by Brian Robison 06 Jan '20

06 Jan '20

Hi, ChucK users! I'm having a problem that seems like it should have a simple solution, but I can't figure it out. Here's a program which plays a WAV (which is about 1.5 seconds long) every two seconds, several times: SndBuf buf; "d3-fa.wav" => buf.read; 0.2 => buf.gain; 2000 => int notelen; for (0 => int i; i < 20; i++) { 0 => buf.pos; buf => dac; notelen::ms => now; } Each time (using ChucK 1.4), it gets louder, and I can't figure out why. What am I getting wrong? Thanks! Brian PS. you can find my d3-fa.wav here: https://drive.google.com/file/d/1B0ZNnGNcF5BKGzmYpdMYdZOO5SbC_4FQ/view

Mojave/Catalina mic access issues
by David Loberg Code 17 Dec '19

17 Dec '19

In OSX 10.14 and 10.15 the System Preference => Privacy settings now have a feature to control third-party access to the mic and camera. The problem my students are encountering is that miniAudicle doesn't show up as an identified app on the list, so they can't click the box to allow access, and thus they can't use adc in ChucK. Is there either: a) a ChucK workaround? OR b) a system file or something to which miniAudicle can be manually added as a recognized app that uses the microphone? Thanks, ----------------- David Loberg Code School of Music Western Michigan code(a)wmich.edu

PLOrk repertoire on Mac help
by Bradley Korth 23 Nov '19

23 Nov '19

________________________________ I could just say that I cannot get LOrk_Path to show up with printenv. Basically, though, I'm trying to setup ChucK and the PLOrk rep using the ChucK Wiki, but I'm running into a problem. I don't have any Macs of my own to use, so I'm using the ones my school has. I can't seem to change the computer's name, but it has hyphens in there. I'm trying to basically get the PLOrk repertoire with ChucK onto the computer, and I just really don't know what to do. I've never used ChucK before. The best I got was editing ~/bash.profile and installing Environmental Variables. I feel like I have even less luck on PC with miniAudicle, and wouldn't really know where to start. For the PC, I mean it doesn't even let me stop the virtual machine like it does on Mac. Hopefully I could get something like ChucK ChucK Rocket or Mirror Dance to work. ::Brad::
