AUDIO BENEFITS TREMENDOUSLY FROM BEING PROCESSED IN PARALLEL LAYERS
When trying to enhance your sound it can be temping to create a large serial chain of FX on a channel as you aim to create a more coloured and textured sound, however this process often creates an over-processed result that doesn‘t sit nicely in the mix. You‘ll achieve a more professional result if you employ good use of parallel processing.
The technique can be done in a few ways but essentially involves duplicating your source sound one or more times and processing each duplicate channel with it‘s own FX chain and then mixing each layer back into the original in parallel.
The benefit of parallel processing is that you can retain the full bodied character of the original sound whilst being able to add subtle layers of processed effects in parallel to achieve an extremely rich and textured sound. Some useful parallel processing techniques and chains are as follows:
Add quality harmonics and air into a vocal or instrument channel: Send parallel channel through harmonic distorter, EQ up hi-frequencies, compress and mix gently back into original. Parallel Pitch shift for innovative texture layer: Send parallel channel into pitch shifter (octave down), run through a hi-pass filter with high cut-off, boost top frequencies with aural exciter and mix back in. The pitch shifted signal through aural exciter creates a lovely extra variation of topend harmonics which you can mix into the original to create texture.
