Multi-Tone Sound Generator
by Oleg Ya. Shmelyoff
Two-channel multi-tone audio frequency sinusoidal signal generator is intended for adjusting and measuring parameters of audio equipment. Independent channels frequency and amplitude controls. 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 to quality of the used sound card.
