I don't know if this is what you are going for, but based on your initial description this is what I envisioned.

I would use frequency modulation to get random pitch fluctuations.
I would use a random pitch oscillator to achieve this too, so it's not predictable like a sin wave would be..

You can see what I did in the screenshot.
I used perlin~ from the else library, it's a pretty good random pitch generator, but there are a few good ones in Else. It's worth trying a few out. I would use a low number, like less than 3 for the frequency of the oscillator doing the modulating.

I used a saw~ for the actual oscillator, and I think that's a Cyclone object.

For a brief explanation: a given frequency is being randomly oscillated within a given range (amount of oscillation). If you want a less wide oscillation change the amount of oscillation. The frequency of the perlin~ ( or whatever noise oscillator you use) is how fast the modulations are happening.

Thank you this is very cool. I can see myself making use of many of these objects

There is a collection of objects called "Sound Design Toolkit," both for Max and Pd. It has a lot of great patches in it. Things like running water, bubbles, engines, scraping sounds. I use it all the time. If you do an internet search you can find some links. I don't know what the latest version is. It's also in the Max collections tab for Max

Hi @whale-av

This is an amazing patch you shared. I think in your application where it's randomly skipping playhead locations it works very well. Since I am kind of scrolling through a patch it didn't seem to work great when I applied the same principles. maybe there isn't really a way to do what I am asking. I will keep messing around with this. ]vline~] is a good idea to duck the volume.

Hi,

I have a patch that is using a phasor~ to play an audio file. I like using this because I can reset where the phasor, between 0 and 1, and scroll through the audio file.

The issue is the way I am doing it is causing a lot of distortion anytime I move the playhead of the phasor. I attached a video link so people could hear what I am talking about.

I also am including the patch so you can see what's going on. I guess this is sort of a question of how I would take this idea into a granular level, instead of just playing an audio file.

Thanks, Nick

Hi. Yes it's a confusing thing to do. I will try and build it and see what happens.

Hi,
Yes let me know what you need or what I can do to help. If you want me to test out ffmpeg let me know.

Hi,

Did you ever manage to get ELSE on Dekken for Linux/ Raspberry Pi?

I have a Pi and ELSE doesn't show up at all in Dekken or in apt get.

I am on an older Pi, 4 model B Rev 1.4. running Debian 10. I Have Pd .56-1.

Let me know if you need help testing it out or something.

Nick

OK, So, for example, would you take two different audio files and play them both for 1000 milliseconds and, with your ears, compare where they are different or similar?

Is this what you imagined? If so that is doable.

Do you need to warp the tempo of a metro? Or the playback of an audio file? Or something else?
