[sdiy] Experiment with bandlimited ramps

[Tom Wiltshire]

Hi All,

I've done some experiments generating bandlimited ramp waves at  
various frequencies and with various numbers of harmonics. The  
results (lots of sound files - page loads fairly slowly) are at:

The idea was to find out practically how many harmonics are required  
for an accurate additive synthesis. Since by the time you're at a  
5KHz fundamental, you'd be lucky to hear the 5th harmonic, I started  
at about 85Hz. These low notes need the most harmonics to sound good.

Have a listen and see what you think.
