The premium version also comes with the following feature set, available also in the free version:
Test your hearing knowledge of the entire range of human hearing...
a quintessential asset for all audio engineers.
This is a quiz that has you hear frequencies ranging from 20 Hz to 20000 Hz.
You'll guess which frequency it is, and get a certain number of points depending on
how close you were. Each frequency tested is a generated sine wave, corresponding to a 31-band EQ.
Use with care; make sure that you turn the volume to a reasonable level to prevent hearing damage.
Try getting 440 points or above for a special treat! (440 Hz is the note that Orchestras tune to.)
Scoring System: 100 pts for the correct answer, -10 pts for each interval away you are away from the correct answer.
Disclaimer: Please use headphones with a frequency response of 20Hz to 20000Hz for the best results, as
your android device may not be able to play all of the frequencies in this range with its built-in speakers.
