An impulse response is a space’s fingerprint. Record a clap in a stairwell, attach the file, and the stairwell is around whatever you process.

Rooms

Four synthesized rooms stand in until you attach a recording: small, medium, hall, cathedral. They differ in length and in how fast the top end dies. They are not measurements of anywhere.

Attaching a recording

Any audio file up to eight seconds. Longer files are cut at eight. A mono recording serves both sides; a stereo one gives each side its own.

Pre-delay and mix

Pre-delay holds the room back by up to half a second, which keeps the direct sound clear in front of it. Mix blends the dry signal with the convolved one; 100 is the room alone.

In the workflow and in Oxyd

In the audio workflow the step uses the chosen room, since a chain carries a name and not a recording. In Oxyd a recording attached to the effect becomes part of the project and is saved with it.

Frequently Asked Questions

A recording of how a space answers a short, sharp sound: a clap, a starter pistol, a balloon, or a sine sweep turned back into a click. Convolving audio with it puts the audio in that space. Anything you can record works, up to eight seconds.

They are synthesized here, not recorded anywhere: decaying noise, different on each side, with the top end fading first. They are a starting point. A recording you attach replaces them.

No. A link carries the settings and the room name, never the audio. A chain opened without the recording falls back to the room chosen under Room.

The convolution works on blocks of 2048 samples, about 43 ms at 48 kHz. The export removes that delay; in the preview the original is held back by the same amount so the comparison lines up.

That one builds a room from feedback combs and allpasses, so its size and damping are dials. This one plays back a measured or synthesized response as it is, so what you hear is that space and only that space.
