Abstract
An apparatus comprising means for: classifying an audio signal as at least a first audio signal for time synchronization with a video signal or a second audio signal not for time synchronization with a video signal; processing the first audio signal for time synchronization with the video signal wherein the processing introduces a first delay for time synchronization with the video signal; processing the second audio signal wherein the processing introduces a second delay shorter than the first delay.
Claims17
An apparatus comprising:
- at least one processor;
- and
- at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
- receive or obtain at least two partially temporally overlapping audio signals and a video signal for processing;
- classify a first audio signal of the at least two partially temporally overlapping audio signals for time synchronization with the video signal by classifying the first audio signal as a non-speech signal;
- classify a second audio signal of the at least two partially temporally overlapping audio signals not for time synchronization with the video signal by classifying the second audio signal as a speech signal;
- process the first audio signal for time synchronization with the video signal wherein the processing introduces a first delay for time synchronization with the video signal;
- and
- process the second audio signal wherein the processing introduces a second delay shorter than the first delay.
A method comprising:
- receiving or obtaining at least two partially temporally overlapping audio signals and a video signal for processing;
- classifying a first audio signal of the at least two partially temporally overlapping audio signals as a non-speech signal;
- classifying a second audio signal of the at least two partially temporally overlapping audio signals as a speech signal, wherein the second audio signal is to be processed with less delay than the first audio signal;
- processing the first audio signal wherein the processing introduces a first delay;
- and
- processing the second audio signal wherein the processing introduces a second delay, wherein the second delay is shorter than the first delay.
A non-transitory computer readable medium comprising program instructions stored thereon that when executed by at least one processor perform at least the following:
- receiving or obtaining at least two partially temporally overlapping audio signals and a video signal for processing;
- classifying a first audio signal of the at least two partially temporally overlapping audio signals as a non-speech signal;
- classifying a second audio signal of the at least two partially temporally overlapping audio signals as a speech signal, wherein the second audio signal is to be processed with less delay than the first audio signal;
- processing the first audio signal wherein the processing introduces a first delay;
- and
- processing the second audio signal wherein the processing introduces a second delay, wherein the second delay is shorter than the first delay.
