Whistles and oscilliscopes

brownja · Post by **brownja** » Wed Jul 11, 2001 10:19 am

Has anyone ever 'scoped a few different whistles to see what aspects of the waveform correspond to such nebulous terms as "mellow" "bright" "chiff", etc. etc? I have some ideas about what i'd expect to see. Does anyone know of a good software based 'scope that can use the soundcard as an input. Or I'll have to borrow a friend's HP.
Has anyone ever thought about or actual done this?
Cheers,
jb

I don't know how good it is, but there is a freeware program at:

Good Luck

I never tried this but I'm just wondering if a spectrum analyzer would give better information than an oscilloscope?

Feadan, Thanks for the link. Although it is from Russia, I hope I haven't been rooted.
Jduffy, You're correct, the types of things i was thinking of, frequency spread, harmonics, etc. do require a spectrum analyzer.
Thanks to both of you. I'll let you how I make out. It'll be a week or two before I have time to fool around.

Try a program called G-Tune by JHC Software
It is a tuner with an oscilliscope and a (I think) spectrum analyzer

Email me and I could send it to you!

We looked into my sound with program called CoolEdit or something, I think it was free. My Clarke seemed to output just simple sine wave, with harmonics in each octave (and nothing else).
