Abstract
A method that includes a decoder-side method that includes receiving a bitstream that includes an encoded representation of an input audio signal and metadata associated with the input audio signal, producing a decoded representation of the input audio signal by decoding the encoded representation using a Matching Pursuit (MP) coding-based algorithm, producing audio driver signals by rendering the input audio signal based on the metadata, and driving speakers using the audio driver signals.
Claims23
A decoder-side method, the method comprising:
- receiving a bitstream that includes an encoded representation of an input audio signal and metadata associated with the input audio signal;
- producing a decoded representation of the input audio signal by decoding the encoded representation using a Matching Pursuit (MP) coding-based algorithm;
- producing a plurality of audio driver signals by rendering the input audio signal based on the metadata;
- and
- driving a plurality of speakers using the plurality of audio driver signals.
A decoder-side device comprising:
- at least one processor;
- and
- memory having stored instructions which when executed by the at least one processor causes the decoder-side device to:
- receive a bitstream that includes an encoded representation of an input audio signal and encoded metadata associated with the input audio signal;
- produce a decoded representation of the input audio signal by decoding the encoded representation using a Matching Pursuit (MP) coding-based algorithm;
- produce a plurality of audio driver signals based on the decoded representation of input audio signal and the metadata;
- and
- drive a plurality of speakers using the plurality of audio driver signals.
An encoder-side method, the method comprising:
- receiving an input audio signal of a piece of audio content and metadata relating to the input audio signal;
- encoding, using a Matching Pursuit (MP) coding-based algorithm, the input audio signal;
- and
- transmitting the encoded input audio signal and the metadata to an audio playback device.
