I've been re-running spectral estimation on high-resolution 16-bit transfers of SYNTHESIS.

With a 12th-order Burg AR model, the pole is located at z = 0.9992 * exp(j * 2 * pi * 14.2 / Fs).
Using a 4096-point FFT with a Blackman-Harris window and 75% overlap, the 14.2 Hz peak is 42 dB below full scale.

Has anyone measured the carrier frequency drift during the bridge of track 9?

Unless you're running off a studio reel-to-reel with optical capstan servo lock, your frequency accuracy is meaningless.

That's how the 14 lines of the Stardust matrix are encoded. Each regional pressing contains one line of the decoded text.
