Description of Function Generator

Dual channel function / waveform / signal generator for the speaker / headphone audio output.
No Ads, No Permissions, No In App Purchasing, No Limited Features. Full Version.
Output is 16 bit for each left and right channels and at 44.1kHz. Output will depend on your device hardware. Some device hardware may may filter out the DC bias and low frequency signals. At high frequencies, the waveforms will be distorted due to limited number of samples for each waveform (for example at 4.41kHz, a sine waveform will be approximated by only 10 points). Therefore this is for fun/educational use, for critical applications use a real calibrated function generator.
Left and Right audio channels can be assigned to either channel 1 or channel 2.
Sine, Square & Triangular waveforms.
Frequency range from 1 mHz up to 22 kHz.
Amplitude as percentage 0-100%.
Set duty for square waveforms or skew triangular waveforms to get saw waveforms.
Offset the phase of waveforms.
Sweep frequency or amplitude (Single, Repeat & Bounce modes).
Amplitude Modulation (AM).
Frequency Modulation (FM).
Burst mode for a specific number of waveforms (1-10000).
White noise & pink noise Generator. Pink (1/f) noise falls of at ~3dB per octave between 43 Hz and 44 kHz.
Memory slots to save & recall channel configuration.
Select values with spring slider or number pad.

    Square wave doesn't work correctly.

    Capable and flexible, a very good app. I need it to keep running (providing output) in the background so I can use it to drive spectrum analyzer apps. I turned off android battery optimization for the app but it still stops when I bring another app to the foreground. The output function button turns off when moved to the background, maybe an easy improvement.

    Thank you very much for the wonderful software! I have been using it for the past few years before getting an actual function generator

    Perfect! Just what I was looking for. A tone generator to try some ideas with. Thank you!

    Does exactly what it says; works great. Flexible mapping of left/right output to generator channels. No annoying interstitial ads. Caveat: landscape mode only.

    Super useful for things like tuning, testing a car stereo, or even finding the perfect frequency to blow dust out of your phone's speakers!
