Audio Function Generator 4+

Something was rattling in my car when playing music through my stereo. Problem was it would only rattle on certain bass notes and no song would create the rattle long enough for me to find it. It had driven me nuts for months!

I picked up a cassette adapter to pipe my iPhone audio into my car stereo. Then I purchased this awesome App and immediately pulled up the Musical Note menu. Starting at the bottom, I began stepping up the note scale until BAM! There it was! I was able to reproduce the rattle.

You won’t believe what I found. My spare garage door opener was vibrating inside my plastic glove box every time a bass guitar hit that note. From that moment, this Audio Function Generator from Thomas Gruber became worth 100 times what i paid for it. Thank You Tom! You rescued my driving sanity.

This is a good looking app aesthetically and delivers solid, intuitive controls. All the functions are easy to use and provide more tools than the average person will use. That means it won’t run out of functionality as you learn to use it for various things. I love the inclusion of various types of noise which I can use to burn in speakers or relax and fall asleep to. The sweeps are great for testing and recording impulse responses and impedance curves. So many more uses that I won’t take up your time and will just say that it would be hard to find a better all-in-one tone and function generator out there. And it’s super affordable for even the tightest budgets. 5/5 stars!

I love this app. I've been studying and using frequencies for over 10 years now. I finally found an app that not only let's me go beyond whole number to decimals, but also let's me type in the exact frequency I want to run. No inaccurate sliders to fiddle with here. I use it regularly. I love the new sets feature.

One thing I would like to see added is the ability to name the frequencies. I use different frequencies for different purposes. It would be nice to name Schumann Earth freq instead of having to memorize Earth is 7.83hz.
