Patent ID: 8423355

Claim:
A method for encoding audio frames, the method comprising: producing, using a first coding method, a first frame of coded audio samples by coding a first audio frame in a sequence of frames; producing, using a second coding method, at least a portion of a second frame of coded audio samples by coding at least a portion of a second audio frame in the sequence of frames; producing parameters for generating audio gap filler samples, wherein the parameters are representative of either a weighted segment of the first frame of coded audio samples or a weighted segment of the portion of the second frame of coded audio samples; and producing the parameters for generating the audio gap filler samples, wherein the parameters are representative of both the weighted segment of the first frame of coded audio samples and the weighted segment of the portion of the second frame of coded audio samples; wherein the parameters are based on an expression: ŝ g ( n )=α· ŝ s (− T 1 )+β· ŝ a ( T 2 ) wherein α is a first weighting factor of a segment of the first frame of coded audio samples ŝ s (−T 1 ), β is a second weighting factor for a segment of the portion of the second frame of coded audio samples ŝ α (T 2 ) and ŝ g is representative of the audio gap filler samples.
