"Amazingly Simple and Fascinating."

Amazingly Simple and Fascinating.

I use spectrograms at work and this implementation is very clean and hardy. I've been tapping glasses, whistling, singing, and seeing if it makes a workable lie detector since getting it.

Birder and naturalist

I also use this program for studying bird and insect sounds. It was already extremely good before this update. Now on an iPad it looks so beautiful that I am trying to figure out a way to carry one conveniently in the field along with my iPhone.

Analyzed Guitar Audio.

A remarkable application. I have used it in a variety of audio environments and was pleased with the resulting displays. The manual gain worked well to adapt to quieter and louder environments. I particularly liked when it analyzed the output of my guitars. I could see the single note I played plus it's harmonics.

Grants a new appreciation for the world.

I took my sense of hearing for granted before using this app. Being a very visually-oriented person, I've found that the world has become much more interesting now that I can conveniently visualize sounds.
