Title: Frequency analyis in CEP
Post by: splumer on December 01, 2010, 12:59:23 PM
This is actually two issues. First, I don't know how to post screenshots, and even with a search I can't find it. And a screenshot would really help illustrate my question, which is...

I recorded a tone generator into Cool Edit Pro, then looked at the wav in spectral view. There's a bright, orange and yellow band that runs from about 200 Hz up to about 2000 Hz. What frequency would you call that? There's no frequency listed on the tone generator, and no model number or anything. It's just a Neutrik XLR connector with a red LED on the end.

Thanks.

most are 1k tone.  The impedieince of your premap might cause the tone to swing a bit one way or another.....

Did you actually try the "frequency analysis" feature of CEP, or just the spectral view?

As far as your question goes, "What frequency would you call that?"  I call that a tone generator with a frequency of 200hz-2000hz.  :-)

I did the spectral view at first, but just now I did the frequency analysis and there's a spike around 1000, then it tapers off to about -72db for the rest of the scale, up to about 22kHz. Would that make it a 1kHz tone?

If I could figure out how to post screenshots, we could have this figured out in no time.

yep, I think you got yourself a 1k tone generator...
