W Generator

W Generator is an easy-to-use app that can play various types of waves including sine wave from 20Hz to 20kHz. Moreover it provides waves with note names and is able to play many chords with different kinds of waves. Lower frequency wave from 20Hz to100Hz would be too quiet to be heard due to frequency characteristics of iPhone’s or iPad’s default speakers and the human ear’s sensitivity, which would cause higher frequency wave from 18kHz to 20kHz to be so. However, with headphones or add-on speakers which have good frequency characteristics, lower and higher frequency waves might be heard more clearly. Higher frequency wave might not be heard because of aged high frequency loss.

Warning: Extremely High volume could be damage your ears using headphones or add-on speakers.

How to change frequencies, notes, chords, gain, waves and modes:

1. Frequencies
Tap frequency numbers to increase frequency.
Swiping up and down frequency numbers will increase and decrease frequency respectively.

2. Notes
Tap note names to change notes forwards.
Swiping up and down note names will change notes forwards or backwards respectively.

3. Chords
Tap note names to change root notes. Swiping up and down note names can change root notes forwards and backwards respectively.
Tap chord types to change chord types forwards. Swiping up and down chord types can change chord types forwards and backwards respectively.

4. Gain
Tap gain numbers to increase gain.
Swiping up and down gain numbers will increase and decrease gain respectively.


5. Waves
Tap wave buttons with wave forms to change waves. No buttons to select cannot output.

6. Modes
Tap mode buttons to change modes. No modes to select cannot output.
