I will try using audio processing and placement tricks to make the radio louder if it is not loud enough. Basically use stuff like equalization and compression. (Yes I know compression does not really make stuff louder, it's really the make up gain that is applied after the compression that makes it louder.) / (Yes I know you cannot magically push a speaker pass it's limits.)
I heard the common reasons for using DJ drops is for promotional purposes and as a type of safety tool to prevent people from stealing your own mixes.
Apparently people steal DJ mixes and pass it out as there own... Those are like two reasons I heard about for why DJs play a bunch of DJ drops in their mixes. I understand the first part about promotional purposes, but I am questioning the second part. How much protection does this offer from someone stealing a DJ's mix? Can't someone who is a like a pro audio expert strip it out of the mix? (Then again why would a pro audio expert be going around stealing people's mixes???)
I heard that you can use strategies to make the DJ drops hard to remove or implement them in such a way that even if someone did remove them the mix will get damaged which may make it unusable. Kind of like a self destruct.
So the DJ drop is kind of like the DJ's audio watermark.
