About

DSD Mastering Viewer

Features
Read full description

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 β€’ The wideband spectrum out to 176 kHz, well past the limit of hearing β€’ How the level above the audio band is shaped, and where it starts to rise β€’ Left/right coherence β€” whether ultrasonic energy is independent between channels, which is what decides whether it can read as width and air β€’ 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 confidence qualifier and the evidence behind it β€” DSD64 heritage, a freshly remodulated PCM or DXD master, a native high-rate capture, an analogue or heavily processed transfer, an upsample from a lower rate, or a lossy-encoded source. A recording-chain grade out of ten scores what the chain delivered: real bandwidth, an honest container, and a clean region above the music. CONVERSION Convert between DSD and PCM in either direction β€” DSD64 through DSD2048, PCM from 44.1 to 384 kHz in 16-bit, 24-bit or 32-bit float β€” with an optional linear-phase filter that removes inherited ultrasonic noise while leaving everything audible untouched. The chart draws the predicted result before you commit to it. HONEST BY DESIGN A file that cannot carry 50 kHz is never reported as having nothing there; it is reported as unobserved. Confidence is capped when there is less evidence to go on. The verdict always hedges, because a spectrum constrains a file's history without proving it. And the grade is explicitly a judgement of the production chain, not of how the record sounds β€” no spectrum can tell you that. Reads DSF, WAV, AIFF, FLAC, ALAC and CAF. Nothing is uploaded; there is no networking code in the app at all. FREE FOR THREE DAYS Everything is open for three days. After that the Viewer and the Converter are separate one-time purchases β€” no subscription, nothing renews, and either one covers all your Macs, iPhones and iPads.
