Decoder, encoder and method for volume estimation based on information using bypass speech object signal in object-based speech coding system

摘要

A decoder is provided for generating an audio output signal that includes one or more audio output channels. The decoder receives an audio input signal including a plurality of audio object signals, receives volume information about the audio object signal, and renders information indicating whether one or more of the audio object signals should be amplified or attenuated Is provided with a reception interface (110). Further, the decoder includes a signal processing unit (120) for generating one or more audio output channels in the audio output signal. The signal processing unit (120) is configured to determine a volume compensation value according to the volume information and the rendering information. Furthermore, the signal processing unit (120) is configured to generate one or more audio output channels in the audio output signal from the audio input signal according to the rendering information and the volume compensation value. One or more bypass audio object signals are utilized to generate an audio output signal. In addition, an encoder is provided. [Selection] Figure 9
