Eight-channel multi-tone audio frequency sinusoidal
and noise signal generator is intended for adjusting
and measuring parameters of audio equipment. Works
with 16, 24 and 32 bit sound cards at sampling rate up
to 384 kHz. WDM drivers support. Independent channels
frequency and amplitude controls. Adjustable phase
shift between channels. Up to eight oscillators per
channel with separate frequency and level setting. A
step of frequency setting is 0.00001 %; level - 0.001
dB; phase - 0.001 degree. The minimum coefficient of
nonlinear and intermodulation distortion, precision,
stability and range of frequency are limited only by
quality of the used sound card. The Sweep Frequency
Mode with adjustable rate in linear or logarithmic
scale. Multi Oscillators Sweep Frequency Mode.
Generation of noise: white, pink (1/f), Brownian
(1/f^2). Mode of amplitude modulation of one channel
by another. Real time signal synthesis. Recording of
synthesized signals to hard disk. The demo is
completely functional, but the time of sounding is
limited to 15 seconds after each clicking of
