heard about it from chris on his rift amps youtube channel. easy to use great for showing you what your ears are hearing

Scale ranges can’t be customized and cannot see low frequencies below 20Hz and DC value. If this were fairly clarified, which it isn’t, I would not have purchased this as it is really useless when those features are what you need.

This app does exactly what it claims to and looks great. I’ll be using it in the classroom soon to demonstrate concepts like “narrow sound frequency band”. Thanks!
