This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped.

This interface defines the event for audio elements triggered when the Audiobuffer is full.


Attribute Type Description
frameBuffer Float32Array The frameBuffer attribute contains a typed array (Float32Array) with the raw audio data (32-bit float values) obtained from decoding the audio (e.g., the raw data being sent to the audio hardware vs. encoded audio). This is of the form [channel1, channel2, ..., channelN, channel1, channel2, ..., channelN, ...]. All audio frames are normalized to a length of channels * 1024 by default, but could be any length between 512 and 16384 if the user has set a different length using the mozFrameBufferLength attribute.  Read only.
time float The time attribute contains a float representing the time in seconds of the first sample in the frameBuffer array since the start of the audio track.
