Abstract
An apparatus for generating one or more audio output signals from one or more encoded audio signals according to an embodiment is provided. The apparatus comprises at least one entropy decoding module for decoding encoded additional audio information, when the encoded additional audio information is entropy-encoded, to obtain decoded additional audio information. Moreover, the apparatus comprises a signal processor for generating the one or more audio output signals depending on the one or more encoded audio signals and depending on the decoded additional audio information.
Claims37
An apparatus for generating one or more audio output signals from one or more encoded audio signals, wherein the apparatus comprises:
- at least one entropy decoding module for decoding encoded additional audio information, when the encoded additional audio information is entropy-encoded, to acquire decoded additional audio information, and
- a signal processor for generating the one or more audio output signals depending on the one or more encoded audio signals and depending on the decoded additional audio information.
An apparatus for encoding one or more audio signals and additional audio information, wherein the apparatus comprises:
- an audio signal encoder for encoding the one or more audio signals to acquire one or more encoded audio signals, and
- at least one entropy encoding module for encoding the additional audio information using entropy encoding to acquire encoded additional audio information.
A method for generating one or more audio output signals from one or more encoded audio signals, wherein the method comprises:
- decoding encoded additional audio information, when the encoded additional audio information is entropy-encoded, to acquire decoded additional audio information, and
- generating the one or more audio output signals depending on the one or more encoded audio signals and depending on the decoded additional audio information.
A method for encoding one or more audio signals and additional audio information, wherein the method comprises:
- encoding the one or more audio signals to one or more encoded audio signals, and
- encoding the additional audio information using entropy encoding to acquire encoded additional audio information.
