Patent ID: 7337025

Claim:
A method for coding audio data signal implemented in an audio data encoder having a neural network exponent strategy processor and an exponent encoder, the data including a sequence of exponent sets each comprising a plurality of exponents, the method comprising the steps of: receiving the sequence of exponent sets as input to a first neural layer and as input to a second neural layer of the neural network processor; determining a first variation of exponent values within a first exponent set; determining a second variation of exponent values between said first exponent set and each subsequent exponent set in said sequence, wherein the steps of determining the first and second variations are performed utilizing the neural network processor, the first neural layer computing weighted sums of its inputs to determine the first variation for determining how many times, if any, a coding strategy for the first exponent set is reused, and the second neural layer determining a coding strategy for exponents in the first exponent set; assigning an exponent coding strategy to the first exponent set based on the determined first and second variations and transmitting the exponent coding strategy to the exponent encoder; and configuring the exponent encoder to encode the first exponent set in the encoder according to the assigned exponent coding strategy.
