摘要： A method derives at least three audio signals, each associated with a direction, from two input audio signals. In response to the two input signals, a passive matrix generates a plurality of passive matrix audio signals, including two pairs of passive matrix audio signals, a first pair of passive amtrix audio signals represent directions lying on a first axis and a second pair of passive matrix audio signals represent direction lying on a second axis, the first and second aces being substantially at ninety degrees to ach other. The pairs of passive matrix audio signals are processed to derive a plurality of matrix coefficients therefrom, The processing includes deriving a pair of intermediate signals and urging each pair of intermediate signals toward equality in response to a respective error signal. At least three output signals are produced by matrix multiplying the two input signals by the matrix coefficients.

摘要： "método para aparelho para decodificação de matriz de áudio". a invenção refere-se a um método que deriva pelo menos três sinais de áudio, cada um associado a uma direção, a partir de dois sinais de áudio. em resposta aos dois sinais de entrada, uma matriz passiva gera uma pluralidade de sinais de áudio de matriz passiva, incluindo dois pares de sinais de áudio de matriz passiva, um primeiro par de sinais de áudio de matriz passiva representando direções que ficam em um primeiro eixo e um segundo par de sinais de áudio de matriz passiva representando direções que ficam em um segundo eixo, os primeiro e segundo eixos estando substancialmente a noventa graus um do outro. os pares de sinais de áudio de matriz passiva são processados, para a derivação de uma pluralidade de coeficientes de matriz a partir deles. o processamento inclui a derivação de um par de sinais intermediários e força cada par dos sinais intermediários em direção à igualdade, em resposta a um respectivo sinal de erro. pelo menos três sinais de saída são produzidos por uma multiplicação de matriz dos dois sinais de entrada pelos coeficientes de matriz.

摘要： A method, an apparatus, a computer readable storage medium configured with instructions for carrying out a method, and logic encoded in one or more computer-readable tangible medium to carry out actions. The method is to decode audio data that includes N.n channels to M.m decoded audio channels, including unpacking metadata and unpacking and decoding frequency domain exponent and mantissa data; determining transform coefficients from the unpacked and decoded frequency domain exponent and mantissa data; inverse transforming the frequency domain data; and in the case M
