Hello everyone!
   Sorry, for those on LAU, this is kind of cross posting.
   I'm looking for a way to stretch audio in the extreme. does csound perhaps 
contain something like hypermammut by Paul Nasca? A module to stretch audio 
for effects or extreme listeneing (50% upwards) with good results?
   Kindest regards and thanks
            Julien

To be more clear. Check these are the relevant opcodes:

pvsanal
pvsynth
pvsbuffer
pvsbufread
pvsblur
pvsmooth

Best,

Peiman

Not sure what your platform is...
  ( I wish people on this list would mention it as a matter of course.  
Most times  I just ignore posts that don't.)

anyway, you could try

http://margaretnoble.net/blog/stretched_toperfection/

It's a blog entry about Nasca Paul's sound stretching software.  Free,  
for Linux or Windows.  Only 1.78 MB unzipped.  It's optimized for VERY  
long time stretches.

I think the original question was if Paul Nasca's algorithm could be  
achieved with Csound.

Oh - sorry Pieman, - told you i ignore mostly :-) ..

Short answer then is "could be achieved by whom?"
and answer is "no" unless they have his algorithm, I guess.

I don't know the exact ins and outs of Nasca's code but from what I've  
heard the programme uses a very large window size and probably  
randomises the FFT bins' phases to smooth the result. The same effect  
could easily be achieved with the pvs opcodes.

Best,

P

yep - I'm not disagreeing - but, with many of these things, the devil  
is in the detail.
It would be nice though. A colleague reports excellent aural results  
with Nasca's algorithm:

"Like Harry Partch once said (about one of his instruments) "It does  
only one thing, but that one thing it does very well."  I'm just  
listening to some stretched birds with it, and the results are very  
nice indeed.  Highly recommended!"

Hello!
   Thanks Peiman for all the info.
   David, just to tell you, I'm on Linux, which in this case was mostly beside 
the point, as I really wanted to find a good way to do extreme stretches WITH 
CSOUND. My problem, why I don't use Paul Nasca's software: I'm blind. So 
csound is a perfect environment for me.
   Kindly yours
            Julien

There was some discussion on the developers list about adding phase
locking and transient detection to the pvs tools in Csound. If these
techniques were implemented they would lead to far better time
stretching, it's just a question of whether Victor or Richard(or
anyone else for that matter) will have the time to implement them in
the near future.
