Priming

This app was built with the intention to better learn the "tuning in" or the "priming" in audio engineering to the human ear.

Ensure that the proper feedback frequencies can be better guess, this app helps by fast and predefined frequency selection and the acoustic output on a smartphone from them.

Moreover, to dispense with the 21 pre-defined fixed frequencies in the piano format and the frequency range by slider or manual input of 9 Hz - 22,000 Hz preset and output acoustically.

Functions:
- Piano keys , with 21 fixed preset frequencies in Hz (100, 125, 160 , 200, 250 , 315, 400 , 500, 630 , 800, 1k, 1.25k , 1.6k , 2k, 2.5k , 3.15k , 4k , 5k 6.3K 8k and 10k)
- Acoustic rendering with continuous mode or as long as a piano key or the slider is touched
- Volume setting
