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 channel sand 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 wave-forms 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 wave forms.
Frequency range from 1 mHz up to 22 kHz. Amplitude as percentage 0-100%. Set duty for square wave forms or skew
triangular waveform to get saw wave forms. Offset the phase of wave-forms. Sweep frequency or amplitude (Single,
Repeat &Bounce modes).
Amplitude Modulation (AM).
Frequency Modulation (FM).
Burst mode for a specific number of wave forms (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.
