question about test CDs

Room Acoustics Forum by Rives Audio

Welcome! Need support, you got it. Or share you ideas and experiences.

I notice that the Rives Audio Test CD is designed to find room modes, but the test tones are only 1/3 octave apart. Isn't this too widely spaced to find room modes?
The CARA Test CD has 28 tones from 16Hz to 200Hz, which means that they're spaced about 1/7.41 octave apart. ((28-1)/log2(200/16) = 7.41). I hope this isn't too confrontational on the Rives forum, but wouldn't this be more useful for finding room modes?
Are there any test CDs out there that have 1/10 octave (or tighter) test tones?
