ASIOSigGen 2.18
ASIOSigGen generates sine wave test signals of the highest possible accuracy (internal calculations at 80 bits), with 0 DC and linear tapering, in the full range of 10 Hz to 22050 Hz, at attenuation values from 0 to 60 dB.
As well, you can select from 9 octaves of musical notes with extreme precision, thus becoming a precise standard reference for the modern Even Tempered Scale to which you can calibrate your equipment and musical instruments. Only for ASIO audio! (Generally only professional sound cards install with ASIO drivers) Supports sound cards with default internal format of 16, 24, and 32 bits (For example, M-Audio's Delta series, Digigram's VX222v2, Sound Blaster's Audigy 2).
