PlayHz plays the sound wave specified with waveform, frequency, amplitude, and phase-shift.

# App Features:
+ You can choose a waveform from the following: Sine, Triangle, Sawtooth, or Square.
+ You can synthesize four waves at the maximum.

# Notices:
If you require more accurate wave, you can select high sampling frequency. Default sampling frequency is 8KHz; Maximum sampling frequency is 48KHz.

High sampling frequency affects good for especially waveform other than sine wave.
But, high sampling frequency needs more CPU power, this app may not work well depending on your device.
