AudioGraph International ::. Synthesizer Techniques


Synthesizers work by manipulating electrical signals that appear as sound when they are used to drive audio amplifiers. These tones are generated by electrical circuits that work by manipulating a signal through a series of oscillators and filters in an analog circuit, or through algorithmic manipulation of signals using a microprocessor and DSP, or by a combination of both techniques.

This can sound difficult and boring to the creative mind, but the reality is that knowing about synthesis can unlock creative barriers and snap you out of a mental block in an instance. Imagine the possibility to create complex sounds out of nothing, and the power that could bring to your individual and unique sound. Imagine as well the inspirational power behind new sounds, and the intellectual reward you can bestow upon yourself from knowing how to achieve the exact sound you are looking for. Give yourself this gift and put yourself ahead of the game.
