Discrete Wavelet Transform external synthesis/analisys available?

Carlo's icon

Hi,
does anybody know if someone has ever been implemented an external for Discrete Wavelet Transform (DWT) analisys and/or synthesis?
Thank you very much.

I did recently as part of my masters thesis, I hope to make them available over the next couple of months.

There is also the source code for one in the CNMAT objects (called wavelet~), it uses the GNU scientific library so you'll need that to compile it.

less effective but more interesting would be patches in that field.

Thanks John,
I didn't remember that there was one in Cnmat's external package.
I hope to see your DWT externals posted in maxobjects.com as soon as
possible.
Best,

Carlo

I'd be interested to know more about this as well. (I'm just posting to make sure any updates to this thread get forwarded to my email.)

bump, bump...

Still curious about this one.

No sorry, haven't had a chance to get to it yet, soon really!

I might just compile a binary for the CNMAT wavelet~ object if it is still not available and people would like? Unfortunately I don't have access to a Mac so it would be windows only.

There's a Mac UB binary here:

^Links is down.
Is this still a thing?

I think you go to
http://www.cnmat.berkeley.edu/downloads
and download (all 18 meg of) the max external objects and the wavelet object will be included

The link has changed, as noted. Also, CNMAT's externals are now available through the package manager.

I don't think the wavelet~ object is distributed anymore, because the license for the GNU scientific library conflicts with the license that University of California demands for the software. You could build it yourself from the source code in CNMAT's github repository. Or, there's a wavelet function in IRCAM's Mubu package, which is also available from the package manager.
