Hi.
I made an audio effect based on autoconvolution. This effect is very interesting and it it's quite non-intuitive.
Here you can find the software (python source code with documentation) and some audio examples.

I highly suggest you to listen many audio examples from the above page and to check some remixes made with it.
Enjoy

Paul

Powerful tool! Could be a great companion to PaulStretch. Any chance for EXE build?

''To run this software you need Python with Scipy installed.''

...Already have too much stuff installed on my computer and to be honest I don't like the idea of installing more resources & stuff just to test / demo an experimental tool. Too bad. I feel I won't be the only one. Sad cause it could be a very nice tool for sound exploration and design.

Any plan for release it a compiled ready to use software/build maybe? Just like Paulstretch? That way I am sure you would get more people trying and using it.

Yes, I know that having a Windows EXE version would be a great thing.
I am quite busy now (I am relocating) and unfortunately I don't have time to reimplement it with a GUI (or to test py2exe). Even the documentation I wrote today was written in a hurry

Any willing to help Python dev here?

Paul- listening to these examples... just ridiculously beautiful possibilities here. SOOOO gorgeous.
I remember reading (and ...trying...) about using vocoding as a means of reverb but * I * never got the hang of it, so when I was reading the description here I was hoping it would be as great as I had imagined it POSSIBLY being back when I was first introduced to that cousin of an idea (same signals for mod/carrier in the vocoder experiments vs self convolution) and I have to say this completely surpasses expectation.
cannot wait to see/hear where YOU or others take this!

Once again, Kudos, SIR!

Thanks for advice. Been there, done that

Having a play and this does some very nice things with vocals. Kudos, thank you.

You executed this script on Linux?

OSX but I suspect it amounts to the same thing. I installed python, scipy, and libav (to get avconv). At that point the script ran perfectly.

I failed to run this code using WinPython distribution. Python shell barked about every quote character in files. Today I will try Anaconda distro, hope it will work better.

I think there are Python to .exe programs. Has anyone used one of these?

I have the audio samples looping. Dreamy!

It is in Python 2.x so Python 3.x will "gripe about quotes." It's really griping about the "print" - in 3 it's a function and needs parentheses, in 2 it's a statement and you don't need parentheses. This is also how to tell an American Georgian accent from a Caucasus Georgian accent.

And if you've ever written even a Visual Basic program, let this cool tool be your gateway drug to SciPy. You *will* grow a new brain lobe, guaranteed.
