hello

i am wondering if you have any suggestions about creating spectrum files that contain audio below 44 hz?

I am analyzing some fm waves and i am wondering whether it will have a significant impact on my spectrum files.

thanks rafe

Depending on how bright the spectrum is, you might be able to get away with recording the sample played at a higher rate (thereby raising the frequency) and analyzing the "pitched-up" version of the sample. In the SumOfSines you can pitch it back down to its original pitch (and independently scale the onDuration by the same ratio to stretch it back to its original duration).
