Audio Convolution Reverb
Put a clip in a real space, or through a speaker cabinet, by convolving it with an impulse response recorded there and loaded with Load Audio. The node plays the clip before and after and draws the impulse response's measured decay.

Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| audio | AUDIO | The clip to reverberate. | |
| impulse | AUDIO | The impulse response, at most 30 s after length and stretch. Mono = the same space on every channel; stereo on a mono clip = a stereo result. A batch pairs clip by clip. | |
| pre_delay | FLOAT | 00–500 | Milliseconds the reverb starts late. `0` = as recorded; `30` = keeps a voice clear of its tail. |
| length | FLOAT | 0.000–30 | Seconds of the impulse response kept, faded at the end. `0` = all of it; `1.5` = a shorter decay from the same space. |
| stretch | FLOAT | 1.000.5–2 | Factor on the impulse response's duration. `1` = as recorded; `0.5` = a smaller, brighter space; `2` = a larger, darker one. |
| low_cut | FLOAT | 00–2000 | Hertz below which the reverb is cut. `0` = off; `100` = clears boom; `300` = thin. |
| high_cut | FLOAT | 00–24000 | Hertz above which the reverb is cut. `0` = off; `8000` = softer; `4000` = dark. |
| normalise | BOOLEAN | true | `true` = the impulse response is brought to unit energy, so mix sets a sane level; `false` = used at its recorded level. |
| mix | FLOAT | 0.300–1 | `0` = the input unchanged; `0.3` = a reverb on a dry track; `1` = the reverb only, for a send or a cabinet. |
| output_db | FLOAT | 0.0-24–24 | dB applied to the result. `0` = unchanged. |
| tail | FLOAT | -1.0-1–60 | Seconds added past the input for the reverb to ring out. `-1` = the impulse response's length plus pre_delay; `0` = none, cut at the input's end. |
