Sure, as the convolution filter applies to reverb (which is just a special case of filtering) this link explains it pretty well. The 'impulse response' in this document is the filter kernel. http://www.innerloopprod.com/Reverb.html Terms (in case you're not already familiar):  frequency response of a filter: that graph you see that describes how a filter passes or filters frequencies.  timedomain: can be thought of as something plotted on a graph where (usually) the horizontal axis is time. (i.e. the usual waveform view you see in ReZound is amplitude on the vertical axis and time on the horizontal axis)  frequencydomain: can be thought of as something plotted on a graph where (usually) the horizontal axis is frequency (i.e. left most is 0Hz, on up to the rightmost highest frequency in the signal being plotted this way, and vertically measure how present, the amplitude of, that frequency is in the signal). As it applies to filtering such as lowpass, highpass, etc. The filter kernel is the timedomain of the frequency response of a filter (which usually shown in the frequencydomain). For reverb the filterkernel/impluse response is as long as the reverberation time. For lowpass highpass the kernel are usually considerably shorter.. and I guess it could sometimes be thought of as reverberation in a bucket, or a pillow where the reverb time is very small. Helps?
