getOutputTimestamp abstract method
The
getOutputTimestamp()
method of the
AudioContext returns a new AudioTimestamp
object
containing two audio timestamp values relating to the current audio
context.
The two values are as follows:
AudioTimestamp.contextTime
: The time of the sample frame currently being rendered by the audio output device (i.e., output audio stream position), in the same units and origin as the context's BaseAudioContext.currentTime. Basically, this is the time after the audio context was first created.AudioTimestamp.performanceTime
: An estimation of the moment when the sample frame corresponding to the storedcontextTime
value was rendered by the audio output device, in the same units and origin asperformance.now
. This is the time after the document containing the audio context was first rendered.
Implementation
AudioTimestamp getOutputTimestamp();
