Having received several requests for this, here I am making publicly available a recently developed variation on the ASIOTestSigGen. It generates Window's RIFF Wave Format audio files with stereo, 16, 24, or 32 bit sine wave signals of the highest precision, in the full range of 10 Hz to 22050 Hz, at attenuation values from 0 to 90 dB. It also includes pink and white gaussian noise generators. The complete specifications are available here. The selectable musical notes are calculated to a precision rounded up to 11 decimal places, becoming a precise standard reference for the modern Even Tempered Scale to which you can calibrate your equipment and musical instruments. If you have any comments or problems with this please let me know.
Update March 2017 - Due to several requests, I have created a new version called AudioFileMaker that allows you maximum freedom for all parameters: unlimited files lengths, higher sample rates such as 192000 and 384000 sample per second, and you are not restricted to standard samples rates. It will generate sample bit widths of 16, 24, and 32. If 16 bits is selected dithering is applied.
