I’ve been working on a sound installation that records your voice on a public space and then plays it back on a FM radio transmitter.
Since then, I’ve been searching for different voice activity detection (VAD) algorithms for Pure Data and found very little.
So far, my best lead is this article: https://medium.com/linagoralabs/voice-activity-detection-for-voice-user-interface-2d4bb5600ee3
So I thought I’d share my simple algorithm for VAD in public spaces and ask:
How would you approach detecting voice activity in real-time in a public space with a lot of noises and non-voice signals?
Here's my patch: VAD.pd
Hello! Kind of late to this thread.
Thought I might post my attempt on doing a low pass gate using vanilla objects.
Replaced threshold using >=~ from the heavy library.
And used lop~ since it has similar curves like the vactrol, only fixed attack and release.
Finally, I used a resonant-lowpass filter from the heavy library.
Lots of great info here, thanks guys.
Just thought I would share my attempt on replicating the sounds of Radiohead's Idioteque using only synthesis on Pure data vanilla:
Here's the result:
Patch available here, under the Instruments folder:
My latest effort to create an instrument that somewhat resembles a piano.
Basically it's a Karplus-Strong string with a fixed lop~ at 6kHz with a 240 filtered noise impulse and a filtered saw impulse.
Here I'm using a
phasor~to generate a sinewave and then using
samphold~to create consistent steps for the LFO.
But, now that you mention semi-random steps, then you could have a second LFO in a different frequency controlling the
Using a source like
noise~could achieve those semi-random steps:
Algorithmic Composition // Catarina
A 100% synthesized algorithmic composition made using Pure Data Vanilla 0.49-1. Made for the upcoming Muff Wiggler Discord Collective Album.
Instruments and sounds used are part of my library: pd-mkmr

Is using pd-extended really necessary? Try the lastest vanilla distribution.
I have a slight suspicion it only works with vanilla since the spout for pd/Gem was released in 2016 and the last pd-extended release was in 2013.
Installing GEM on vanilla is way easier now, you just need to download it via deken and write "Gem" on your startup libraries.
Hello pd-fellas, 👋
Here's a new abstraction I made based on Mike Moser-Booth's [curve.mmb~] abstraction from the mmb library.
This version allows you to draw curved ramps into arrays. These can then be used as envelopes, wavetables, GUIs, waveshapers, etc.

Hello everyone, thanks for the mention @Jona!
@MeneerJansen That TR-808 snare is for a client, so I'm unable to share it.
On the other hand, here's a more basic TR-808 kick and snare, it has the basic blocks for it: kick-and-snare.pd
- One oscillator with two harmonics, each harmonic has its own envelope curve and one is more snappier than the other.
- A filtrated noise source with more decay time than the drum layer
You can make it snappier by distorting the first milliseconds.
If you know synthesizer terms you can try and emulate it better using to Adam Schenider's tutorial to make an 808 style snare.
@ingox There is a sample being played for comparison with my synthesized version.
