Abstract
As may be implemented in a manner consistent with one or more embodiment, aspects of the disclosure are directed to latency control with signals, such as audio signals. For instance, a quality characteristic of an audio signal having time-sequenced frames exhibiting a signal quality can assessed, and an output indicative of the signal quality is provided based on the assessment. An amount of latency in the audio signal is dynamically adjusted based on the output, and the latency can be used in processing the time-sequenced frames, such as to use future frames in assessing or correcting a current frame during a time period facilitated via the latency.
Claims20
An apparatus comprising:
- a first circuit configured and arranged to assess a quality characteristic of an audio signal having time-sequenced frames exhibiting a signal quality, and to provide an output indicative of the signal quality;
- a second circuit configured and arranged to dynamically adjust an amount of latency in the audio signal, based on the output indicative of the signal quality;
- and
- a third circuit configured and arranged with the second circuit to:
- for each of the time-sequenced frames,
- assess at least one additional frame associated with the audio signal and corresponding to a future time using time provided via the latency, and
- modify the time-sequenced frame based on the assessment of the at least one additional frame.
A method comprising:
- assessing a quality characteristic of an audio signal exhibiting a signal quality;
- providing an output indicative of the signal quality based on the assessing;
- dynamically adjusting an amount of latency in the audio signal, based on the output indicative of the signal quality;
- and
- assessing at least one additional frame associated with the audio signal and corresponding to a future time using time provided via the latency, and modifying respective time-sequenced frames in the audio signal based on the assessing of the at least one additional frame.
An apparatus comprising:
- an input circuit configured and arranged to receive an audio signal exhibiting a signal quality;
- and
- a computer circuit configured and arranged with the input circuit to
- assess a quality characteristic of the audio signal;
- provide an output indicative of the signal quality based on the assessing;
- dynamically adjust an amount of latency in the audio signal, based on the output indicative of the signal quality;
- and
- assess at least one additional frame associated with the audio signal and corresponding to a future time using time provided via the latency, and modifying respective time-sequenced frames in the audio signal based on the assessing of the at least one additional frame.
