I recall Miller showing me an ISPW patch to do time stretching. I remember it as a pretty big patch taking up, I think, two whole boards (or maybe that was just one whole board). I have looked on my hard disk, but don't see it, but it must be knocking around at IRCAM somewhere. If it is only one board it might be portable to msp (else wait for the 1Gb G3!!).

Actually, I worked with Guy in 1996, and we are using a modified version of his conductor follower software to do exactly this! So we have a rapid sequence of MIDI time "clicks" that give us a good approximation of the current speed and phase. The problem is that we now want to time-stretch digital audio instead of MIDI using that timing information...

Fourier is not exactly my middle name, but does that mean you could preprocess (pre-fft) the entire audio file once, and then do the time shifting and inverse fft in real-time without noticeable delays following a variable clock generated by conducting input, all using csound on something like a PowerMac G3/333? How about adjusting "macro-phase" (play the next beat exactly when the ticks announce the beginning of it)? Jan ------------------------------------------------------------------------ Jan O.

I am considering using them and would appreciate any >info. yes, they work great. you can modulate all the parameters from max/msp, etc. the nice thing is that you get a whole collection of plugins, instead of spending a few hundred dollars for just a "declicker". the pitch-shifting algorithm sounds particularly good, and might work well for the person who wants to do live time compression/expansion. one advantage is that the hyperprism stuff tends to consume less processing power than some other plug ins. the filter and reverb algorithms, for example, consume much less cpu than northpole and roomulator, etc. speaking of the northpole filter, though - it is a great-sounding algorithm... one of the best software filters available, with extras like distortion and delay - and its free - ! check it out: http://www.prosoniq.com/html/sms/sprenger.html -jhno () )) ( ((( )) ) ))))) ( )((()) ( ( )) ( ) ) ( ((( ) (()( (() delicate ear ear@sirius.com san francisco, ca http://www.sirius.com/~ear ------------------------------ Date: Thu, 27 Aug 1998 20:47:03 +0200 From: Oeyvind Brandtsegg Subject: Re: Fast time-stretching with MSP?

Yes, I can't think of a reason why this shouldn't be possible. Of course there will be a delay between the gesture input and the resynthesis output, but that could be avoided by supplying some kind of "negative offset" to the variable clock. Or modify the gesture-processing to "go ahead of the beat" a little. It might also be a question of how high a sample rate you can get your resynthesis to run at. There is an optimised Csound version running on an Analog Devices, Sharc-based card. It's running under windows, but does not depend heavily on host-computer speed (I think), so you might get away with a cheap machine.

Well, I tried this and while I *was* able to deinstall Max witht the memory pulled, when I reinstalled the memory and went to reinstall Max, the installer on the floppy still quits with "unexpectedly quit, error type 1" On the other hand, I *do* see "Max 2.5.2" appear in the menubar before this happens, but the splash screen doesn't appear. again: Sys. 7.6.1, 96MB memory TIA, dc ------------------------------ Date: Thu, 27 Aug 1998 23:01:09 -0500 From: evening Subject: OT: but relevant...kinda I heard about this app in a news group and thought some of you might = be interested...
