waon: the quality of result is improved by cleaning up useless notes.
gwaon: horizontal keyboard is added on the spectrum pane.
rpm is built on openSUSE machine. enjoy!
add mannual pages (waon.1, pv.1, gwaon.1).
clean the codes.
add the interactive curses mode with real-time time-strech and pitch-shift.
add no-fft scheme (just for fun).
update about window and the GUI, adding buttons for each function.
WaoN is a Wave-to-Notes transcriber (converts audio file into midi file) and some utility tools such as gWaoN, graphical visualization of the spectra, and phase vocoder for time-stretching and pitch-shifting.
ports for FreeBSD is now available.
pv: -rate and -pitch can work together.
gWaoN: add pitch-shift scale.
This release is mainly for a bug fixed and two functionality addition for WaoN.
Also, some default parameters are adjusted for WaoN and pv.
gWaoN: use ao libary, loop-play, play-position indicator, loose phase lock PV.
pv: bug fixed on loose phase lock, use ao libary, pitch-shifting.
WaoN: get rid of my old sox-derived code.
This is for gWaoN upgrade; it has functionality of audio playback with the real-time tempo change by phase vocoder.
two additional programs, gWaoN and pv, are added.
pv is yet another phase vocoder for time-streching.
The code is working for analyzing sound file. See the web for the instruction. (http://waon.sourceforge.net/gwaon.html)
now WaoN uses libsndfile for input, so flac is directly processed! also a new option --phase is added to improve freq estimation by phase-vocoder technique.
stereo wav can be handled properly,
work with either FFTW version 2 or 3.
