TooB Convolution Reverb
Convolution reverb is a notoriously compute-intensive effect. If you are having performance issues, use the Max T control to constrain the length of the impulse file to under two seconds. The Max T control affects how much of the impulse file is used. If the length of the impulse file is longer than the specified time, samples occurring after the specified time are discarded, and the tail of the impulse convolution is fed back into the input of the convolution. This ensures a smooth reverb tail, and has little effect on the quality of the resulting reverb. If the impulse file is shorter than the specified time, then all samples in the impulse file are used, and no feedback occurs. You can often get smooth reverbs that preserve most of the character of the impulse file with Max T set to 250ms or less. Because reverb impulse files often include the original sound, you will sometimes get strange comb filter effects if you use the Direct mix control; but this varies depending on the impulse file in question. Usually, the Direct mix control should be set to -INF. The Predelay control determines whether Toob Convolution Reverb will strip leading silence from the impulse data. Turning it on preserves leading silence in the impulse signal; turning it off removes leading silence. If the the Direct mix control is set to -INF dB, there's no real point in delaying the convolution reverb output; you want responses as quickly as possible. The Predelay control should be set to off. The leading silence in impulse files can sometimes be quite significant. If the impulse file has 4 channels, Toob Convolution Reverb assumes the signal is in Ambisonic b-format, and down-mixes the ambisonic channels to mono. To generate stereo reverb effects from ambisonic audio, use the stereo version of this plugin. Toob Convolution Reverb comes with a nominal set of reverb impulse files to get you started. You are strongly encouraged to explore the rich collections of reverb impulse files that are widely available on the internet.
