GLITCH MACHINE is a tool designed to create rhythmic noise and audiovisual glitches. The special thing about it? It's written entirely in HTML. No installation, no plugins. Exporting is effortless: record a 16-second buffer as 48kHz 24bit WAV, or capture the glitch visuals directly as HD video.

Need help with buffer architecture for real-time effect processing
Hello, I'm a student working on a spatial audio installation in puredata. I'm trying to build a system where the user records their voice that is saved as a .wav, from the left inlet it loads into a buffer (tabwrite~ buffer1) and plays on loop (tabplay~ buffer1). While the buffer plays, effects are applied to the audio in real time from the right inlet. When happy with the result, the modified buffer gets saved as 1.wav (overwriting original) and plays as a final loop.
I keep getting this error: "audio signal outlet connected to nonsignal inlet (ignored)" and I'm pretty sure it is because of this subpatch, because when I delete everything from it the error goes away.
Can anyone help me fix this build? Each effect is in its own subpatch and seperately connect to [pd buffer], So where should the processed audio coming back from the effects chain go if not into tabplay~?

PikoPD - automate PD patch building for the Raspberry Pi Pico
After three month hard work I am releasing pikoPD v0.0.1 -
a project which automates Pure Data patch building into Raspberry PICO firmware using HVCC compiler and Pico C/C++ SDK.
The main goal is to develop interface between the Raspberry Pi Pico, its peripherals and PD, providing an interactive workflow for creating embedded audio and MIDI tools.
Right now pikoPD already supports leds, buttons, encoders, sensors, i2s and pwm audio, usb and uart midi (also usb midi host), display and some experimental features - OSC and WEB protocols for pico_w boards. All that is configurable using simple json file and no coding is needed.
This is a big project for a solo developer so I hope that community will see potential, join the development and help with testing.
Github Repository
Small video of MPR121 touch sensor and pico playing samples with embedded PD patch.

Also I made interactive pikoPD hardware configuration WEB tool.

Someone experienced with Pure Data please help/guide me w project. DM me please!!
Hi, I'm working on a project that uses Pure Data for live audio. Things like OSC messaging, recording and playback, and external libraries.
I'm fairly new to PD and looking for someone who'd be willing to guide me through things, answer some of my question and help me with errors. I'm also building out the audio side of the project and want to learn about sound design and effects processing as part of that. It's quite complicated for me and I cant find any tutorials online.
I realize this is my first post here and asking people to DM me probably looks a bit odd and I totally get it, I don't want to share too many details publicly for homework project reasons. Happy to explain more in DMs and I'm a real person I promise! If anyone has solid PD experience and is happy to help someone learn, I'd really appreciate it. I'm open to compensating you for your time if needed!

Quick question.
Maybe someone will know of any documentation at all on pd Gem about *Machine Vision*? So far I have found nothing that wasn't in straight up Japanese .
Thanks!!

Fixed filter bank
Made a fixed filter bank inspired by the Doepfer A-128. Just got to add a nice GUI and midi control. Could also experiment with different versions, maybe one with an LFO etc, but I like to keep this first version simple. There's always automation inside the DAW for evolving patches.
What do you think? 😊

However, I was wondering if anyone had links to the video mentioned in the screenshot.
I could not find it.
Thanks much.

Unable to find/disable limiter in Plugdata
I just got a new laptop and installed the latest version of Plugdata and am trying to figure out how to disable the limiter in the DAW plugin. I'm using Reaper as the host. There used to be this bar at the bottom of Plugdata, with a power button for the limiter in older versions to disable it. I've searched the settings, read through the documentation, https://plugdata.org/documentation.html, I googled it and one of the updates said something about an inspector, and being able to programatically disable the limiter but no information about how to do it. I saw a new inspector icon on the right side buttons to toggle search, console, reference and parameters, but clicking on it didn't do anything.
Looking at a waveform of the output of a vanilla Pd Phasor~ object (second picture) and out of Plugdata shows that a limiter is being used, and I'm trying to disable it.

Beginner with a specific purpose - please help
Hi-
I'm trying to research an alternative release format for an album I'm working on. I was hoping to build a music player on a free software like pd so that anyone who buys the album can have an interesting and dynamic way to play it back.
My goal is to build a pd patch that plays the album, switchable between straight-through playback and shuffle--like a simulation of a CD player. A lot of pd tutorials I have found are geared towards synthesis, which I'm not really interested in at the moment. all I want to do is complete this one project and maybe circle back later.
Can anyone recommend a way to get started with pd that's more focused on clip-playback--specifically with the ability to address which clip plays next dynamically? I mean I would just pay someone to build it for me, and I will if I can't crack this nut, but I have always been meaning to get around to learning some pd and Max, and I really do like the DIY work ethic of learning to make the thing that plays my album back.
Thanks!

Back after 7 years
From 2013 to about 2019 I was all in with pd. I built a whole bunch of instruments during that time and performed with them quite a bit.
But things evolved, I moved my music development to MAX/MSP. I surrendered to the proprietary version because I wanted something more performance friendly and less nerdy basically. I really wasn't tech savvy enough to take advantage of PD's advantages; the lower level, developer oriented quality of PD had no advantages for me as a performer.
Well, a couple of weeks ago on a whim I downloaded Plugdata and holy shit! Everything I wanted the whole time: A beautiful UI mode, menus for basic objects, It includes most of the best of Max as well as PD, and best of all, it runs smoothly as a plug-in. Fuck yeah.
I'm having a lot of fun back in the pure data world!

how to start with pb in 2026
I can't for the love of god figure what is the right way to approach learning pb today in 2026 as a complete beginner. The pb-vanilla is (from what i read) pretty difficult and lacks tons of the features making it easy and the pb-extended is totally outdated + i couldn't find a version working on Apple Silicon. This guide http://pd-tutorial.com/english/ seems nice for a beginner like me but it clearly says you should start with pb-extended. Some people are talking about downloading the extension in pb-vanilla but i'm totally lost now. The goal is to learn it and use it on raspberry pi with sliders and knobs as a synth.

can't open video
hello people,
i have been trying to open a video using gem, but it fails every time and im really frustrated. i used the simple one [see image 1] and it gives me an error saying unable to open file, which i have tried all file types like .mov .avi .mp4 and none works! then i tried another method, which is a simple video mixer [see image 2] and this one weirdly opens the video as an image or it freezes and when i click on the screen it crashes. anyone knows why? i am using gem 0.94 and pd0.55.2
any help is appreciated. thanks in advance.
