Left and right channels seperated, delay line implemented

I seperated my left and right channels in my DSP code. Initially the audio signal was interlaced ie. the left and right channels were getting processed in the LRLRLRLR... fashion.

Also, I tried reading samples off of my delay line ie. tried to access past samples but discovered that only the sample before the current one is being read into the delay buffer. A simple code change should fix this.

At this point, I want to consult somebody and ask them if I'm doing things in a clean way before I go on.
