The restorer's note

The real-time spectrum bench, which we could not resist teaching to hold. Freeze a frame and it becomes a drone; gate the quiet bins and it becomes a filter. The measurement is honest; the effects are ours, added lightly.

Listening

Listening

Demonstration recordings, prepared at the bench.

  1. Plus four per octave

    The pad runs dry for five seconds, then returns through the analyzer with Tilt at +4 dB/oct — the spectrum redrawn brighter than it arrived. FFT Size holds at 2048.

    0:00 / 0:30

  2. Gate rising

    FFT Size at 512. Gate rises from −90 to −30 dB across fourteen seconds: bins below the threshold go dark and the pad thins to its loudest partials. The threshold falls away at twenty-two and the rest returns.

    0:00 / 0:30

  3. Held frame

    FFT Size at 8192, Smooth raised to 80 %. Freeze engages at ten seconds and the analyzer holds its frame — the chord becomes a surface — until it lets go at twenty-four and the pad moves again.
