[OT] talking piano-- new take on analysis/resynthesis

thought this might be of interest to some of you-- maybe one could do an RT version in max...

edit-- just realized it was first posted a year ago; old news, apologies for the noise
time to get back to work...

I remember a lecturer on our Music Tech Master's playing this video, of a caged flame being bombarded with extremely high amplitude sound waves (I think), turning the flame into a loudspeaker.......just as freaky

Paul deMarinis is a fabulous artist-- I saw his 'edison effect' installation a number of years ago in Sydney-- it was pretty inspiring stuff...

I saw an installation of that talking piano some years ago. It is by Peter Ablinger, a german composer. I remember seeing a laptop beneath the piano, running PureData. Maybe pd just played midi data - but who knows...

Peter Ablinger gave a 3-minute talk on the "piece". He only mentioned that it involved a sophisticated algorithm for finding the best resynthesis, on which he worked for a long time.

I think there might be some publications on this technique, as this approach is quite popular with some instrumental composers of so called "spectral music".

if you want to take a shot at this, i think sigmund~ would prove handy.
its got a resynthesis subpatch in the helpfile.

The big difference is that sigmund~'s resynthesis uses sine waves.
When doing "resynthesis" with real instruments you have to take into account the whole spectrum produced by one note. I think that's the tricky part...

PS:
two corrections to my previous post:
Peter Ablinger is actually from Austria (sorry ;)
The Analysis software was written by Thomas Musil (IEM Graz)

yes, i know, but that resynthesis subpatch can be easily hacked to spit out midi data for a player-piano.
but it won´t be easy to adjust, you are right.
