DSD Mastering Viewer

DSD Mastering Viewer reads a DSD or high-resolution PCM file and works out, from the spectrum alone, what production chain it most likely came from. A file labelled DSD256 may be a genuine high-rate master, or a DSD64 SACD transfer in a larger container carrying an older modulator's noise as content. A 192 kHz download may be a real 192 kHz capture, or a CD upsampled into an empty band. The container never says which. The ultrasonic region does. WHAT IT MEASURES • The wideband spectrum out to 176 kHz, well past the limit of hearing • How the level above the audio band is shaped, and where it starts to rise • Left/right coherence — whether ultrasonic energy is independent between channels, which is what decides whether it can read as width and air • A band table from 15 kHz upward, in dB relative to the music WHAT IT TELLS YOU A plain-language verdict naming the most likely chain, with a…
