I found that a pink noise track in a test CD is not reliable.

Any suggestion for a reliable test CD?

Test CD (TCDE 863902. C 1996. Disky Communications Europe B.V.) track 16 pink noise ?10dB has +8dB peaks at 50Hz and 160Hz.

In contrast, The Sheffield/Coustic Set Up and Test Disc track 18 pink nose does not have those peaks.

Measured with Gold Line DSP-30 real time anylazer.
1/3 octave band.
Weight: flat.
Line input.
( the pink noise from Gold Line pink noise generator does not have those peaks either.)
