FM Synthesis using two Oscillators
Abstract Sounds that originate form nature have amplitudes of the frequency components that are ‘time variant’ or dynamic, partially due the uniqueness of the sound or in broader terms the randomness of the amplitude of each frequency in the particular sample. In an effort to convert digital sounds into a form that is ‘livelier’ an ADSR (Attack Delay Saturation and Release) envelopes were used. A sound envelop is a graph that dictates how a single note of sound would vary over time. This added a dynamic essence to the digital sounds. For example, with Attack envelope ‘bell’ like sounds with harsh overtones and prominent frequencies could be converted into an organ type sound by increasing the value of attack. However, for the longest time there lacked a process to synthesize organic/natural sounds. To put it simply, sounds that are random and that vary with time. In the September of 1973, John M Chowning submitted a paper for an algorithm for a process to produce complex natural s...
