Spectrum Editor

Spectrum Editor and Sample Editor
Scrub and paint in a time-frequency image with a pen and hear the modification immediately or modify the waveform in the time domain. The two screen shots show the state before and after a "scrub" with the spectrum pen:
ScreenShot before / ScreenShot after

Below is a wave file sample, that shows what you can do with a SpectrumPen. The flute (fundamental and harmonics) has been eliminated with the SpectrumPen (-30dB, a 'rubber') leaving everything else unchanged by simply moving the cursor over the details of the flute sound. The wave file is taken from Windows98, so maybe you don't have to download it (located in C:\Windows\Application Data\Windows\Welcome, or search for Welcom98.wav).
Original WaveFile (178kB) / WaveFile without flute (178kB)
Easy to use graphical filtering
Select arbitrary regions in the time-frequency image by simply painting a mask with the mouse. Delete these selections by pressing Delete. Or copy, paste, amplify, attenuate and move them.
ScreenShot
Basic editing of signals
Cut, copy, delete, insert, add and subtract time segments and arbitrary time-frequency selections like in classical wave editors.
Undo/Redo with unlimited levels.
Playback of sound files.
Jaco can be linked to Matlab (send vectors to viewer with: jaco(x)).
