System and method for optimizing signal processing and storage using frequency-time domain conversion

A method of operating an audio processing system including at least one processing unit coupled to a memory, the method comprising the steps of:

• converting a plurality of sound recording samples represented in a time domain to a plurality of frequency domain sound recording samples represented in a frequency domain using a processor besides the at least one processing unit;
• storing the plurality of frequency domain sound recording samples in the memory;
• reading the plurality of frequency domain sound recording samples from the memory;
• and
• processing the plurality of frequency domain sound recording samples.

An audio processing system comprising:

• a memory storing a plurality of oscillator frequency and magnitude signals and a single unity sine wave reference table;
• and
• at least one processing unit coupled to the memory and including a plurality of oscillator modules and configured to:
• read the plurality of oscillator frequency and magnitude signals and the single unity sine wave reference table from the memory, and
• generate and output an oscillator output using the plurality of oscillator modules based on the plurality of oscillator frequency and magnitude signals and the single unity sine wave reference table.
