Abstract
Un método, un aparato, un medio de almacenamiento legible por computadora configurado con instrucciones para llevar a cabo un método, y lógica codificada en uno o más medios tangibles legibles por computadora, para llevar a cabo acciones. El método debe decodificar información de audio que incluye canales N.n en canales de audio decodificados M.m, lo que incluye el desempaque de metadatos y el desempaque y la decodificación de información de exp onente de dominio de frecuencia y mantisa; la determinación de coeficientes de transformación a partir de la información desempacada y decodificada de exponente de dominio de frecuencia y mantisa; la transformación inversa de la información de dominio de frecuencia; y en el caso M < N, la combinación de reducción de canales de audio de acuerdo con la información de combinación de reducción de canales de audio, donde la combinación de reducción de canales de audio se lleva a cabo de manera eficiente.A method, an apparatus, a computer-readable storage medium configured with instructions to carry out a method, and logic encoded in one or more computer-readable tangible media, to carry out actions. The method must decode audio information that includes N.n channels in decoded audio channels M.m, which includes unpacking metadata and unpacking and decoding information of frequency domain and mantissa; the determination of transformation coefficients from the unpacked and decoded information of frequency domain mantissa and mantissa; the inverse transformation of frequency domain information; and in the case M <N, the audio channel reduction combination according to the audio channel reduction combination information, where the audio channel reduction combination is carried out efficiently.
