Audio Function Generator

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.

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.

I’ve been testing a new idea to reduce tinnitus, ie to listen to the pitch that matches the pitch i hear due to tinnitus. this app has easy to use features and good sound quality. i just wish it would run in the background so i can multitask while doing this therapy. i’ll let you know how well it works to reduce tinnitus. (the idea is the brain creates ringing in the ears to compensate for frequencies compromised due to damage to certain parts of the cochlea. if the auditory nerve can be stimulated at these frequencies, so the theory goes, maybe the brain will stop simulating them)

I use 440 all the time and I like combining it with 73 and the different background noises. I use your app to study and to sleep. Feature request: I would like to identify a few to many different frequencies and play them in order backwards and or forwards or loop and set the length of time to hear each sound. This could be great for practicing scales though this wasn't my original intention. 😊

I have a foreign low frequency (around 60-70Hz) messing up with my ears in my home and I wanted something to easily match the exact frequency I hear. Being able to fine tune the frequency in the free version it allowed me to precisely match the noise that is troubling me (but I still can't identify the source, though) This app is perfect, and the plethora of options in the free version made me review it without being asked to.
