MULTI-CHANNEL AUDIO UPMIXER |
| 摘要 |
An audio processor may receive audio input channels including stereo channels and one or more surround channels. The audio processor may downmix the audio input channels into stereo output channels; developing the stereo output channels into upmixed audio channels including at least one additional surround channel not present in the audio input channels; delay the audio input channels into delayed audio channels that are time-aligned with the upmixed audio channels; and mix the delayed audio channels and the upmixed audio channels into audio output channels. |
