I found this patch (freeze3.pd , scroll down to around post 14):

http://forum.pdpatchrepo.info/search/fft-freeze-help

This seems to work well. Have there been any other good freeze patches in the 4 years since?

I made two phase vocoder abstractions, [cphasevoc~] and [cpitchshift~], based on Miller Puckette's example patch. The first is meant to be used on tables and to my ears it produces less artifacts than [pvoc~]. The second one is used on incoming audio signals.
You can use both for a freeze effect, depending on if you work on tables or live audio.
In the first case, you simply have the reading index of [cphasevoc~] at a constant value or vary it by a small amount to get some variations in sound.
In the second case, [cpitchshift~] has a dedicated 'freeze' method to capture live input. Of course you can also pitchshift the captured sound.
In both cases I'd go for rather large window sizes and set phase locking to zero or slightly above. Together with pitchshifting you can get quite interesting results. Try it on different kinds of source material!

Here are the patches:

cpitchshift~.pd cphasevoc~.pd

Note: [cpitchshift~] requires the object [z~] from zexy.

And 5 years later ...

I can share if anybody still comes here.

Yes please!

Here it is!

freeze_Oct_2020.zip

It’s based on the [freeze3] patch mentioned in the first post.
It uses some other abstractions of mine so I just bundled the whole thing, check the readme.
I can make a self-contained vanilla patch if this is confusing.

This is my first go at spectral processing - feedback and advice much welcome!
Enjoy!

this would be extremely helpful! i would love to try this freeze effect on my bela salt eurorack module and if i am correct it only supports vanilla patches...

anyway, awesome work and thanks alot!

Hi there,

Thanks for the interest!

Unfortunately I'm now caught up in some complex work & home change and I won't find time in another couple of months, really sorry.

I will get back to this thread when I can though, and regarding the patch all the logic is inside de [pd core] subpatch.

Sorry I can't be of much help.
Best,

Here's the same "freeze" patch (later version, cool "auto" mode) integrated with the larger patch "snail" I made for a friend of mine:

As I said I'll be on standby for a while, but any feedback is most welcome. I might clean up , document and post once I'm back on my feet.

I uploaded a temp version in this thread: https://forum.pdpatchrepo.info/topic/13177/snail-a-pure-data-patch-for-slow-sounds

(post deleted)
nevermind... i was too dumb to recognize the bypass switch!
great patch!!!!

Hi there,

Ok so everything is working? You don't have the can't create error anymore?
Let me know if you do we can figure it out.
I'd love feedback too!

Best,

hi gabriel,
i come back to your patch all the time and wanted to ask, if you maybe had time to make a self contained vanilla patch out of the last freeze patch?
it would be amazing to have a vanilla patch which can be used in so many different applications
cheers!

Hi there, sorry for the late reply I had simply forgot about it.
I gave it a deeper look today, and it does seem like quite a job ... Most objects in my library are structured in the same way and use the ELSE externals.
In the coming months I will be working with an artist who might require the freeze patch in vanilla, if this happens I'll make sure I post it here (won't forget .
Sorry about that ...
