Audio Gate
Shut out the quiet parts of a clip, such as room noise between words or bleed between drum hits, with a gate that opens and closes or an expander that eases them down. A sidechain input lets another clip open it.

Inputs (13)
| Name | Type | Default | Description |
|---|---|---|---|
| audio | AUDIO | The clip to gate. | |
| mode | COMBO | gate | `gate` = opens and closes, with hold and hysteresis; `expander` = turns quiet parts down smoothly by ratio, gentler on breaths and tails. |
| threshold_db | FLOAT | -40.0-90–0 | Level in dBFS the gate opens at, or below which the expander turns down. `-40` = speech in a quiet room; `-25` = noisy room. |
| depth_db | FLOAT | 40.00–90 | dB the quiet parts are turned down by. `10` = gentle; `40` = near silence; `90` = off entirely. |
| ratio | FLOAT | 3.01–20 | Expander only: dB of fall per dB under the threshold. `2` = gentle; `4` = firm. |
| hysteresis_db | FLOAT | 4.00–20 | Gate only: dB under the threshold the level falls before the gate closes, so it does not chatter. `4` = typical. |
| attack_ms | FLOAT | 1.000.01–100 | Milliseconds to open. `0.1` = snaps open for drums; `5` = soft for voice. |
| hold_ms | FLOAT | 500–2000 | Gate only: milliseconds it stays open after the level drops. `50` = speech; `200` = keeps a decaying note. |
| release_ms | FLOAT | 1501–5000 | Milliseconds to close. `50` = tight; `300` = natural tails. |
| lookahead_ms | FLOAT | 2.00–10 | Milliseconds the gate opens ahead of the sound, so the first transient is not cut. `0` = off. |
| sidechain_cut_hz | FLOAT | 00–2000 | Hertz below which the detector ignores the signal, so rumble does not open it. `0` = off; `150` = typical. |
| output_db | FLOAT | 0.0-24–24 | dB applied to the result. `0` = unchanged. |
| sidechainopt | AUDIO | Another clip whose level opens the gate, such as a kick opening a bass line. Empty = the clip opens itself. |

| open_share | FLOAT | Share of the first clip the gate was open for, 0 to 1. |
