Queen’s catalog has been remastered several times (2004, 2011, 2022). A verified WAV must state its source. Are you listening to the original 1991 Parlophone CD master? Or the 2011 Universal remaster? Verification includes metadata tracking.

Let’s examine why Greatest Hits II specifically requires WAV verification. Unlike the first greatest hits album, which relied on ’70s production, Greatest Hits II spans the technologically advanced ’80s and the poignant final years.

Verification requires analysis of the frequency spectrum. A legitimate lossless WAV of a rock track recorded in the late 80s and early 90s will typically exhibit frequency information extending up to 22 kHz (the Nyquist frequency for 44.1 kHz audio).

Open the WAV in a spectrogram. A true CD-quality WAV (44.1kHz) will show frequencies cutting off sharply at 22.05 kHz (Nyquist frequency).
