! These patches demonstrate how to use Pd's short-time Fourier transform objects,
! rfft~ and rifft~, to do a variety of things.  The patches can be quite
! expensive; the phase vocoder, for instance, requires a 300MHz Pentium 2 to run
! at 44100 Hz.  By default Pd runs at 44100 Hz, but you can specify a different
! sample rate on the command line, for instance:
! 
! pd -r 16000 09.pvoc.pd
! 
! On SGI, Pd will check whether your audio system is running at the correct
! sample rate and will print out a warning if not.  In NT or W95, Pd's behavior
! will depend on your audio driver.  In Linux Pd usually tries to set the rate
! of the conversion hardware.
! 
! Included in this directory are:
! 
! 01.fftanalysis.pd -- does a windowed FFT analysis and resynthesis of a sine
! tone, showing how to specify block size and overlap.
! 
! 02.noisefft.pd -- Fourier analysis of white noise.  This patch also shows how
! you can average power spectra over time.
! 
! 03.denoise.pd -- using the technique from the previous patch, finds the noise
! floor in a recorded sample and attempts to scrub it away.
! 
! 04.shifts.pd -- tests the leftshift and rightshift "externs" used in the next
! patch.
! 
! 05.sheepgoat.pd -- tries to discriminate between "pitched" and "unpitched"
! components of a sound.
! 
! 06.sheepgoat2.pd -- another attempt at the same thing.
! 
! 07.tinbell.pd -- a spectral flattener, which can make the sound of a large bell
! turn into the sound of a tamtam.
! 
! 08.convobros.pd -- spectral cross synthesis between two sounds
! 
! 09.pvoc.pd -- phase vocoder
! 
! ---------- after this point, the patches haven't been cleaned up -----------
! 
! 10.phaselockedvoc.pd -- phase locked vocoder; see Laroche&Dolson in ICMC97 for
! a discussion of something that works better than this.
! 
! 11.pianorev.pd -- an attempt at a phase-coherent reverberation algorithm to
! imitate the "piano reverb" obtained by putting a speaker under the sound board
! of a piano and picking up the sympathetic vibrations.
  
  12.sinedecomposer.pd -- estimate the frequencies and amplitudes of the
  components of a sound
  
! 13.tracemaker.pd -- show how to use Pd to combine snapshots of a spectrum into
! continuous spectral traces.
! 
! 14.partialtracer.pd -- sinusoidal analysis/resynthesis of a time-verying sound.
! 
! 15.waveformgrab.pd -- bash a sample into phase-coherent windows and make a
! pitched resynthesis.
! 
!

! Most of the patches here have moved to section I of the audio examples.
! The remaining ones are due for an update but will probably join the
! "data" examples.
  
  12.sinedecomposer.pd -- estimate the frequencies and amplitudes of the
  components of a sound
  
! 13.partialtracer.pd -- sinusoidal analysis/resynthesis of a time-verying sound.
