Step windows

Every step of a source’s processing opens in a window of its own, titled with the step and the source. Click the step’s row in Audio Routing to open it. Several can be open at once, each is listed in the Window menu, and they close with the show.

The toolbar

On beside the title turns the step on or off. At the trailing edge, the Preset menu has the step’s own presets (Default puts every setting back; Custom once you changed one), and Hold to Compare: held, you hear the source without this step, at the same delay. See Processing.

The live sound

The input meter on the left, the output meter on the right, and between them a picture of what the step does to the sound now. Make the window larger to give the picture more room.

The settings

Under the picture, the step’s settings as rows, as in the inspector: drag a slider, type a value, or reset it to its default.

The foot

How much delay the step adds (Adds 30 ms) and Remove Step.

Compressor	the level in against out, the threshold, a dot for the live level and the Reduction	Threshold, Ratio, Attack, Release, Gain
an Audio Unit	the unit’s own view	the unit’s own, or its settings as rows. See Add an Audio Unit

The Equalizer

Five bands, edited one at a time: pick one on the curve or in Band, or drag its handle, left and right for the frequency, up and down for the gain. By default only the first does anything: Low Cut at 80 Hz, which takes the rumble away and turns a 50 or 60 Hz hum down. The others are Low (160 Hz), Mid (450 Hz), Presence (3.2 kHz) and High (9 kHz), flat until you raise or lower them.

Setting	Range
Type	Low Cut, Low Shelf, Bell, High Shelf, High Cut
Frequency	20 Hz to 20 kHz
Gain	−20 to +20 dB
Slope (a cut, in place of Gain and Width)	12, 18 or 24 dB/oct
Width	0.3 to 10

The Compressor

The Compressor turns the voice down once it passes Threshold, by Ratio, so loud and quiet words come closer together; Gain brings the whole back up. Attack and Release say how fast it reacts and lets go.

Not installed

An Audio Unit that is not on this Mac shows a message in place of its settings: install it, or remove the step. The step is kept in the show meanwhile, off.
