SCRAPER · The point of it
It draws the cut it makes, and it turns down only the band.
The display is three pictures drawn from the engine's own readings: the cut at each frequency, hatched at the reduction now and dashed at the most RANGE allows, with the band's edges marked where the detector is 3 dB down (a straight line when WIDE is on, because the whole signal is turned down); the band's level against the threshold over the last five seconds, hatched where it is over; and the reduction in dB. One ring on the cut sets FREQUENCY and RANGE, the wheel over it sets Q, and a ring on the level lane sets THRESHOLD.
Every one of the 20 presets is written as what it changes from the defaults and is held to two to four measurements, 60 in all, on programmes made with the sibilance centred on the preset's frequency: how far the bursts come down, how much the voiced part changes, the largest reduction and the delay. The installed Audio Unit and the engine differed in 0 of 1,152,000 samples in each of six stereo settings.
- 0 of 432Runs in which the copy of LATHE's de-esser module differed from the original: WIDE on and off, FREQUENCY 3 to 12 kHz, Q 0.5 to 8, RANGE 0 to 18 dB, THRESHOLD absolute and relative, ATTACK, RELEASE, LISTEN on and off, four sample rates, noise, sibilant bursts and the voice, with the setting moved three times in a run.
- Bit for bitWith RANGE 0 the output is the input, with WIDE on or off and a delay of 0, in the engine's 144 runs and in the processor at six sample rates in both layouts. A denormal input number comes out as itself or 0.
