GLITCH MACHINE A browser-based audiovisual instrument for electronic and experimental music production.

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, no setup. Just double click the file and you're ready in one second.

The interface is immediate — a 5-voice step sequencer with click, pulse, tone, sub and noise burst, each with its own independent pattern. You can build complex glitch rhythms or let it randomize everything in one click. The visual engine generates black and white geometries in real time, synchronized to the sound — data streams, flashes, scanlines, datamosh, all in the style of Ryoji Ikeda.

Exporting is effortless: record a 16-second buffer as 48kHz 24bit WAV, or capture the glitch visuals directly as HD video. Perfect for building sound libraries and noise video content without touching any other software.

To integrate it into your DAW you have two options. If you work with Max 9 and Ableton 12, you can load it directly into Max for Live using the jweb~ object — GLITCH MACHINE runs inside your set like a native device. Alternatively, use a virtual audio cable like VCable to route the audio into any DAW.

How can I create a kaleidoscope visual reacting to audio in Pure Data (GEM)?

Hi everyone, I’m new to Pure Data and currently working on a short workshop project (group of 2). We’re using GEM to create a kaleidoscope-style visual that reacts to an imported audio file.

We would like the visuals to react to audio features such as tempo, pitch, and loudness.

Do you have any tips or approaches to achieve this in Pure Data + GEM?

Also, are there other useful audio features we could extract (besides tempo, pitch, and loudness) that could drive visuals? And what units or objects would you recommend for analyzing them in Pure Data?

Thanks in advance for your help! 🫶

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.

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!
