Exponential Audio R4 Explained® is rated 4.9 out of 5 by 13 .
Rated 5.0 out of 5 by from Useful tutorial with good examples! This is a very good tutorial with good audio examples. What it doesn't do (but neither does the R4 user manual unfortunately), is explain in more detail how the "Attack" and "Early" delays fit in the picture. Everybody knows the typical separation into early reflections and reverb tail, but the "Attack" page in this reverb is new to me and I don't quite understand what exactly it is and how exactly the signal is routed.

Rated 4.5 out of 5 by from Succinct yet detailed R4 run through. Really well done, succinct, but still detailed run through of R4 with some helpful examples. Only thing I wish, and this isn't to disparage this great video series, was that there were tips on what works well or doesn't work well in R4 for certain types of music.
