In Reply to: Figure 1: Digital rip of an HDCD with Peak Extend posted by Christine Tham on December 24, 2005 at 00:04:18:
This is how WMP has decoded the track. Note the attenuation of the entire waveform by -6dB, followed by expansion of peaks, which are now clearly of different heights (louder than -6dB).
