Abstract
Latency on different devices (e.g., devices of differing brand, model, vintage, etc.) can vary significantly and tens of milliseconds can affect human perception of lagging and leading components of a performance. As a result, use of a uniform latency estimate across a wide variety of devices is unlikely to provide good results, and hand-estimating round-trip latency across a wide variety of devices is costly and would constantly need to be updated for new devices. Instead, a system has been developed for crowdsourcing latency estimates.
Claims20
A device, comprising:
- at least one non-transitory memory;
- one or more processors coupled to the at least one non-transitory memory and configured to read instructions from the at least one non-transitory memory to perform steps including:
- receiving first audio feature analysis information associated with a first audio capture captured at a first computing device and a first corresponding audio signal,
- wherein the audio feature analysis information is automatically determined by an audio feature analysis device;
- estimating a round-trip latency through an audio subsystem of the first computing device based on the first audio feature analysis information;
- and
- supplying the round-trip latency to a second computing device for use in connection with vocal performance captures by the second computing device.
