ENCODING AND REPRODUCTION OF THREE DIMENSIONAL AUDIO SOUNDTRACKS |
摘要 |
The present invention provides a novel end-to-end solution for creating, encoding, transmitting, decoding and reproducing spatial audio soundtracks. The provided soundtrack encoding format is compatible with legacy surround-sound encoding formats, so that soundtracks encoded in the new format may be decoded and reproduced on legacy playback equipment with no loss of quality compared to legacy formats. |

1. A method of encoding an audio soundtrack, comprising the steps of:
receiving a base mix signal representing a physical sound; receiving at least one object audio signal, each object audio signal having at least one audio object component of the audio soundtrack; receiving at least one object mix cue stream, the object mix cue streams defining mixing parameters of the object audio signals; receiving at least one object render cue stream, the object render cue streams defining rendering parameters of the object audio signals; utilizing the object audio signals and the object mix cue streams to combine the audio object components with the base mix signal, thereby obtaining a downmix signal; and multiplexing the downmix signal, the object audio signal, the render cue streams, and the object cue streams to form a soundtrack data stream. |
