非标
此特征是非标准的，且不在标准轨道中。不要在面向 Web 的生产站点中使用它：它不适用于每个用户。实现之间可能存在大的不兼容性，且行为将来可能改变。

弃用
This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the 兼容性表格 at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

The non-standard, obsolete, NotifyAudioAvailableEvent interface defines the event sent to audio elements when the audio buffer is full.

特性

frameBuffer 只读: A Float32Array containing the raw 32-bit floating-point audio data obtained from decoding the audio (e.g., the raw data being sent to the audio hardware vs. encoded audio). The data is a series of audio samples, each sample containing one 32-bit value per audio channel. All audio frames are normalized to contain 1024 samples by default, but could be any length between 512 and 16384 samples if the user has set a different length using the mozFrameBufferLength 属性。
time: A floating-point value indicating the time in seconds at which the first sample in the frameBuffer occurs, relative to the start of the audio track.
