Some wav files
A few pure tones:
A.wav 12K
D.wav 12K
Dsharp.wav 12K
Fsharp.wav 12K
440.wav
442.wav
440-442beats.wav
Some different waveforms, all 440 Hz A:
Asine.wav
Atri.wav
Asaw.wav
Asqr.wav
Some chords. I forget what the first chord is.

Douglas Rain, the voice of HAL in 2001: A Space Odyssey
cantdo.wav 103K
Now we apply a "highpass filter" to this, cutting out all frequencies below the given values (400 Hz, etc)
cantdo_hi400.wav 103K
cantdo_hi600.wav 103K
cantdo_hi900.wav 103K
cantdo_hi1200.wav 103K
cantdo_hi1875.wav 103K
Now we apply a "lowpass filter"
cantdo_low400.wav 103K
cantdo_low600.wav 103K
cantdo_low900.wav 103K
cantdo_low1200.wav 103K
cantdo_low1875.wav 103K
Here it is with an echo:
