Object to to produce Time-Frequency Reassigned Spectrograms?

January 24, 2007 | 1:09 am

Is there an object out there that will produce Time-Frequency Reassigned Spectrograms?

Time-Frequency Reassignment improves resolution in both the time and frequency domains. For a brief explanation, see this:

http://www.shout.net/~kfitz/timefrequency.html

I don’t know much about the method, other than that it really works amazingly well. I’ve been using the program SPEAR to do this type of analysis, and I plan to take the SDIF files that SPEAR outputs and plug them into Max, to control the time/frequency/amplitude of a series of Sine oscillators. But it would be nice to do the whole analysis in Max… but I sort of doubt that anything has been built in Max that has the functionality of SPEAR. But I just thought I’d check to be sure, because it would streamline the process…

Here’s a link to SPEAR (it’s free) for anyone that’s interested. It’s the best spectral analysis/resynthesis program that I’ve found, really wonderful… I’m always looking for something better though, so if someone knows of anything beter, please tell me!:

Thanks, any help is appreciated

You need these bad-boys:

and these:

If you search the forum for SPEAR you should find a discussion about it
happening at the moment (SPEAR rules!).

Thanks! I fully agree, SPEAR is awesome!

Don’t know if its comparable, for sure it has tons of features:
Audiosculpt, not free, part of the ircam forum. There are a lot of
respectful musicians which can’t imagine to live without it…

Oops, this mail wasn’t supposed to be sent. I was a little hesitant
to announce the next version of Macaque before a few minute bug fixes.

audiosculpt seems to me like a harder to use version of spear. It just doesn’t feel as intuitive or fun to use. (Im a forum member)

Actually most of the IRCAM software is hard to use, but I use the max/msp stuff all the time, they are wonderful.

Audiosculpt does take a while to get used to but for time-stretch and
pitch transposing is the best thing in terms of sound quality. It’s
worth learning I think. It’s not any more difficult than say protools
or dp is it? The partial tracking in Spears is way better though in
my opinion.

Diphone is of course the only software as far as I know that does
resonant filter analysis. This is the only feature I use diphone for;
I find the morphing impossible I think it requires a lot of tweaking
and knowledge to get a good quality re-synthesis with it which I
haven’t managed yet!

What is Resonant Filter Analysis? Does it use some sort of pattern matching algorithm to tell you if the spectrum probably was produced using a resonant filter, of a given set of parameters?

Hi,

Have a read through this http://www.cnmat.berkeley.edu/SDIF/ICMC2000/
results/CD/software/IRCAM/RodetCIM2000.pdf

Its in section 2.2 of the article
