Comparing non-parametric Welch PSD with parametric Burg autoregressive models for the 14.2 Hz line.

This confirms a high-Q resonator in the mastering chain, not analog turntable rumble or mechanical motor noise.
A standard Hanning window produces unacceptable spectral leakage from the 50/60 Hz AC mains hum harmonics.

I've uploaded the C source for my decimation and bandpass filter to ftp.ashford-poly.edu.

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