Software to test tones

Hi there,

I'm not sure if this is the right forum, and for some reason I can't click on my UN or user CP (yes I'm new to the forum.) It keeps telling me I'm not logged in or I don't have permissions.

Anyway, I have tons of healing frequency tones from YT, & I really need software that will allow me to know what hertz the tones have so I know if they are legit.

I've contacted a couple of sites, only one responded, Ableton, saying the software doesn't detect low frequencies, & I'm sure many of these tones have low frequencies.

This is very important to make sure the tones are authentic.

Please help.

On another note, if anyone knows of easy to use software where I can make my own tones, that would be something I would want to do.

I tried to find someone to hire to do this (I run a non profit), but I couldn't find anyone.

Thanks a ton
