Convolution reverb is a notoriously compute-intensive effect. For best results, 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 occuring after 
the specified time are discarded, and the tail of the impulse convolution is fed back into the imput 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. 

Because reverb impulse files typically include the original sound, you will often 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 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 input file has 4 channels, Toob Convolution Reverb assumes the signal is in Ambisonic b-format, and downmixes the channels accordingly. Unfortunately,
it currently dowmixes the Ambisonic audio to mono. Exepct a stereo version of Toob Convolution Reverb in the near future, which will make better use of
Ambisonic source material. 

Toob Convolution Reverb comes with a nominal set of reverb impulse files to get you started. You are strongly encouraged to seek out reverb impulse files 
on the internet. 

Special thanks are extended to the the OpenAir project, wich graciously provided the base set of impulse files distributed with Toob Convolution Reverb under 
licensing terms that are compatible with the Toob Amp project's licensing terms.
