Re: [AN1x-list] Filter frequency in HZ

2001-10-30 by Phil

Well, for starters:

Middle A = 440Hz

(Double it for each octave up the keyboard)
(Half it for each octave down the keyboard)


Hold a sec, I just did a search and look what my local uni have come up
with:

Now how's that?!!

Subject: [AN1x-list] Filter frequency in HZ


I was wanting to do some 'formant' based synthesis and realized I
didn't have any herz numbers in my synth manual. I recall some
lengthy discussion we had about LFO frequency in Hz, but I don't
recall anyone mentioning a resources for the filter frequency. I
believe Jon had an LFO table handy, and I am hoping something similar
will turn up in this case.

I guess if there isn't a Hz table out there, I can always get the
filter to self-oscillate and find the closest note from my other
synths. I am not trying to nail any particular note, just get close
to the resonant frequencies for the human voice.

Anybody done this yet? I'd appreciate if anyone knows any
shortcuts....Also, does anybody know where I can find a pitch (note)
to herz conversion table......

Thanks in advance,

Jerry

PS: If I do this, I'll post my results, in case somebody else gets a
similar crazy yearning. :)
