AudioContextOptions dictionary (used when
AudioContext) may contain a property named
latencyHint, which indicates the preferred
maximum latency in seconds for the audio context. The value is specified either
as a member of the string enum
AudioContextLatencyCategory or a
audioContextOptions.latencyHint = "interactive"; audioContextOptions.latencyHint = 0.2; var latencyHint = audioContextOptions.latencyHint;
The preferred maximum latency for the
AudioContext. There are two ways
this value can be specified.
The best way to specify the preferred latency is to use a value form the string enum
AudioContextLatencyCategory. In fact, the default value of
"interactive" (meaning the browser should try
to use the lowest possible and reliable latency it can).
The value can also be specified as a double-precision floating-point value, specifying the preferred maximum latency in seconds. This provides more precise control over the balance between audio latency and device energy usage.
To determine the actual latency of the context after creating it, check the value of
The definition of 'AudioContextOptions.latencyHint' in that specification.
