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 <nowiki>[channel1, channel2, ..., channelN, channel1, channel2, ..., channelN, ...]</nowiki>. 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. | 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).
