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 07 Jan '20

07 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
