Sound Frequency Generator

The Sound Generator is a multi-channel multitone sine and noise signal generator designed for tuning and measuring audio equipment. Works with 16, 24 and 32 bit sound cards with sampling rates up to 384 kHz. WDM drivers are supported. Independent frequency and amplitude adjustments across channels. Adjustable phase shift between channels. Up to eight oscillators per channel with independent frequency and level settings. Frequency setting resolution is 0.00001%; level - 0.001 dB; phase - 0.001 °. Minimal coefficient of nonlinear and intermodulation distortion, accuracy, stability and frequency range are limited only by the quality of the sound card used. Frequency oscillation mode with adjustable rate of oscillation on a linear or logarithmic scale. The mode of synchronous frequency change of several oscillators. Noise generation: white, pink (1/f), Brownian (1/f 2). Mode of amplitude modulation of one channel by another. Synthesis of all signals in real time. Ability to record synthesized signals on disk. Demo version is fully functional, but the sounding time is limited to 15 seconds after each pressing of the "Start" button. Registration removes the demonstration limitation.
