Re: [chuck-users] MultiTap delay

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

Hi Everyone! Wath is wrong in this code? // Using SndBuf to play a sound file // by ChucK Programmer, December 2050 SndBuf mySound => dac; // get file path me.dir(C:\Program Files (x86)\ChucK\audio\123.wav) => string path; // sound file we want to play "/audio/123.wav" => string filename; // + sign connects strings together! path+filename => filename; // tell SndBuf to read this file filename => mySound.read; // set gain 0.5 => mySound.gain; // play sound from the beginning 0.1 => mySound.pos; // advance time so we can hear it second => now; //

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

Also .pos is an integer but here it’s set to a float (0.1).

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::

Good afternoon, I'm trying to link Miniaudicle to IanniX. I've been able to receive messages in Chuck through OSC. But I didn't get these messages to ring Chuck. It's not easy, really. Does anyone have an example of Chuck with a Dani seño 3/2 D program? Thank you folk!! Enviado desde mi iPhone
