Re: Is anyone interested in a DVD-Audio disc containing test signals?

Yes! I would like this very much!

Nobody seems to think about equipment tests anymore, only speaker tests, but I like to analyze distortion in various ways, starting with THD and THD+N. For high frequencies, the my LAUD/Fiji analyzer won't cut it, and I have to use a slow HP analog spectrum analyzer instead. So what I want is:

Sine waves that last a while, not just 15 sec (I hate those), but 1-10 minutes for a good slow spectrum scan.

For example, 1Khz for 5 minutes would be very nice.

Also, some higher frequencies, starting with 20K - 30K. 1 minute apiece would be OK.

Also, a good 19+20Khz "IM" test, for at least 5 minutes so I can scan deep into the millihertz. Make it 10 minutes if possible. This is a great test! Nothing is "perfect" on this one.

Also, a linearity test at 0, -10, -20, -30, -40, -50, -60, -70, -80, -90, -95, -100, -105, -110, -115, -120, -125. This could all be at 1Khz, each for 1 minute.

I've been getting so fed up with the typical 15 sec test tone disks, I've been thinking of burning my own 80 minutes of 1Khz CD.
