SPECTRAL COMPARISON
Hear the change.
Keep the original.
A controlled look at spectral repair.
One synthetic sound. Four ways to hear it.
An added 6 kHz tone gives this experiment a known target. Compare the real rendered outputs below.
3 s / stereo / 24 kHz
AVERAGE SPECTRUM Original Candidate
The candidate attenuates the added tone. The musical harmonics remain visible.
0.00 / 3.00 s
CHOOSE WHAT YOU HEAR 1–4
Which do you prefer?
Original and candidate, in random order. No results are collected.
Ready. Start quietly, then switch while playing.
WHAT TO LISTEN FOR
The high tone becomes less prominent in the candidate. Switch back to Original to hear what changed.
WHAT THIS DEMONSTRATES
A bounded treatment with a known reference. This is pre-rendered experimental audio, not recovery of a missing master.
