Mad Man H.,If you like the concept of multitone signals, then you need to look into my Phi Spectral version of a multitone, see:
http://www.geocities.com/jonrisch/PhiSpectral1.htmThis is AES preprint #4803, and some of the graphics are shown at:
http://www.geocities.com/jonrisch/page10.htm
and related pages.Most of the mainstream multitone test signals all make a significant mistake by having the multiple tone frequencies in the signal prone to octave or other similar spacings that allow cover-up of various distortion products by the original tones in the test signal.
If you would like a PDF of the paper, which has all of the graphics in it, e-mail me, however, it is 3.4 Meg in size, so I would not recommend this way via dial-up. I can send hard copy via snail-mail, but for international mailings, I would require some of the international mailing coupons to cover the costs.
If I had a fax number, I could fax a copy, but even with the FAX set on fine, many of the graphics would be mangled. If you send me a fax #, please include all the necessary country numbers, etc.
