I thought -that might make it difficult to understand the "reverb" part of the code. Once you -figure out how Freeverb works, you should find it trivial to add such features with -little CPU overhead. - -Technical Explanation ---------------------- - -Freeverb is a simple implementation of the standard Schroeder/Moorer reverb model. -I guess the only reason why it sounds better than other reverbs, is simply because -I spent a long while doing listening tests in order to create the values found in "tuning.h". It uses 8 comb filters on both the left and right channels), and you -might possibly be able to get away with less if CPU power is a serious constraint -for you. It then feeds the result of the reverb through 4 allpass filters on both -the left and right channels. These "smooth" the sound. Adding more than four allpasses -doesn't seem to add anything significant to the sound, and if you use less, the sound -gets a bit "grainy". The filters on the right channel are slightly detuned compared -to the left channel in order to create a stereo effect. - -- cgit v1.2.1
