Flashback Shimmer

How it's made

Source

a bell struck once and played backwards: instead of a sharp strike followed by a decay, every partial grows from silence and is cut off at the moment the strike would have happened.

Body

bell partials relative to the nominal pitch (hum 0.5, prime 1, tierce 1.2, quint 1.5, nominal 2, 2.5, 3, 4.2). Low partials ring longest, so reversed they start growing first; upper partials enter late, which makes the swell brighten as it rises. Each partial is a slightly detuned pair that beats and carries a slow shimmer tremolo.

Air

band-passed noise whose centre rises with the swell (suction before the strike), then a short soft breath of high-passed air after the cut-off that fades out as the airy ending.

Envelope

exponential growth per partial (the mirror of an exponential decay) and a 25 ms release at the peak to avoid a click.

Variation

`rng` mistunes partials by up to ±0.4 % and shifts the pair beating; presets change length, pitch, brightness, shimmer and air.
