[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.
