Ableton/Live/UG/29 Audio Effect Reference/32 Reverb/05 Global Settings
- Predelay — ms before the first early reflection; affects perceived room size. Natural values are about 1–25 ms.
- Smooth — how Size changes take effect: None jumps (may cause artifacts), Slow or Fast glide.
- Size — room volume; very large gives a shifting, diffuse delay, very small a colored, metallic sound
- Decay — time for the tail to fall by 60 dB
- Freeze — holds the diffuse sound almost forever.
- Flat — bypasses the shelf filters while frozen, so the frozen sound does not lose energy in those bands
- Cut — stops new input adding to the frozen sound
- Stereo — width, from mono up to 120°, where each ear gets an independent tail
- Density — quality versus CPU, from Sparse to High
