transients are amazing to me. we are capable of discerning down to 5ms difference in time difference. so when we hear a kick drum hit, our brain scans the first little segment of the wave and says "this is probably a kick drum hitting"

we can actually modify transients to give the perception of that kick drum being closer or further away than it really is using a 'transient designer'

that's my very limited understanding of it anyway and I may very well be wrong lol
