SGenerator is a high-quality 2 channels signal generator for your iOS device (iPod Touch/iPhone/iPad) with wide frequency range (1 Hz - 20000 Hz).

Create sine waves, square waves, triangle waves, saw waves and white noise. Amplitude modulation and channels summary are available also.

You can:
• testing speaker systems
• balancing home theater speakers levels
• testing and tuning audio amplifiers, equalizers, crossovers and many other equipment.

You can enter frequency (phase) values enter manually or with help of knobs in two modes (coarse and fine). You can use sweep frequency mode.

Phase shift for both channels for iPad and for second (R) channel only for iPhone/iPod

Link frequency mode - link frequency of second channel to first channel.

Internal oscilloscope and level meter for better clarity.

Generator is accurate, reliable, precise, and clean.

Three calibrated master output level modes (0.7V, 1.0V, 1.4V)

Note that non-sine waves have perceived transient processes that some distort ideal output from above about 1400Hz.
