Very awesome & useful

This is a very awesome and useful app. I’ve been using this for audio filtering and cognitive dissonance purposes. Works awesome with “Audiobus” mixer. What would make the app better is if the user could adjust the phase for each wave such as 45 and 360 degrees as audio and AC operate both on the electromagnetic radiation spectrum. What would also help would be to add green noise. Very high quality. YOU guys are awesome and “Tech Nerd Culture” approves.

Fantastic app

Fantastic app. Especially when used in conjunction with spectrum analyzer. Up to 16 frequencies to 21khz. Sine, square, triangle, sawtooth options. Can set sweep range and amplitudes. White and pink noise generators.
Suggestions for increased functionality:
-option to allow running app in background
-option to view waveform generated.
-option for more colors of noise
Provides smart phones with incredible flexibility. Valuable acoustic tool.
