摘要： A method for inserting a first audio signal into a bitstream which comprises a downmix signal and associated bitstream metadata is described. The downmix signal and associated bitstream metadata are indicative of an audio program comprising a plurality of spatially diverse audio signals. The downmix signal comprises at least one audio channel and the bitstream metadata comprise upmix metadata for reproducing the plurality of spatially diverse audio signals from the at least one channel. The method comprises mixing the first audio signal with the at least one audio channel to generate a modified downmix signal. The method further comprises generating an output bitstream comprising the modified downmix signal and the associated modified bitstream metadata indicative of a modified audio program comprising a plurality of modified spatially diverse audio signals.

摘要： A method for encoding a multichannel audio input signal, including steps of generating a downmix of low frequency components of a subset of channels of the input signal, waveform coding each channel of the downmix, thereby generating waveform coded, downmixed data, performing parametric encoding on at least some higher frequency components of each channel of the input signal, thereby generating parametrically coded data, and generating an encoded audio signal (e.g., an E-AC-3 encoded signal) indicative of the waveform coded, downmixed data and the parametrically coded data. Other aspects are methods for decoding such an encoded signal, and systems configured to perform any embodiment of the inventive method.

摘要： The present document relates to audio encoding / decoding. In particular, the present document relates to a method and system for reducing the complexity of a bit allocation process used in the context of audio encoding / decoding. An audio encoder (300) configured to encode an audio signal according to a first audio codec system is described. The audio encoder (300) comprises a transform unit (302) configured to determine a set of spectral coefficients (312) based on the audio signal. Furthermore, the encoder (300) comprises a floating-point encoding unit (304) configured to determine a set of scale factors and a set of scaled values (314), based on the set of spectral coefficients (312); and to encode the set of scale factors to yield a set of encoded scale factors (313). In addition, the encoder (300) comprises a bit allocation and quantization unit (305, 306) configured to determine a total number of available bits for quantizing the set of scaled values (314), based on a first target data-rate and based on the number of bits used for the set of encoded scale factors (313); to determine a first control parameter (315) indicative of an allocation of the total number of available bits for quantizing the scaled values of the set of scaled values (314); and to quantize the set of scaled values (314) in accordance to the first control parameter (315) to yield a set of quantized scaled values (317). Furthermore, the encoder (300) comprises a transcoding simulation unit (320) configured to determine a second control parameter (321) based on the first control parameter (315); wherein the second control parameter (321) enables a transcoder to convert the first bitstream into a second bitstream at a second target data-rate; wherein the second bitstream accords to a second audio codec system different from the first audio codec system; and wherein the first bitstream comprises the second control parameter.
