Attributes
| 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. |
