I have been using a technique for big bottom bass and it works really well. I use Adobe Audition. These are completed stereo mixdowns. I isolate the low-bass, then pitch-stretch down 1 whole octave. Then I boost that up +3 or even +6 dB, then mix-paste with the orignal file. MY QUESTION(S): Is there a name for this? Are there any common rules I should follow when using this technique? Do I need to rolloff at say 40 Hz before or 20 Hz or so after doing this? I am using this for southern-rock type of material and it sounds fantastic. Is this technique used in hip-hop material to get that low-low bass? Is there a (free?) plugin available for this purpose? Thanks in advance, and if you would like to hear some samples I have plenty.
