The '''mozFrameBuffer''' attribute contains the raw audio data (float values) obtained from decoding a single frame of audio. This is of the form <nowiki>[left, right, left, right, ...]</nowiki>. All audio frames are normalized to a length of 4096 or greater, where shorter frames are padded with 0 (zero). | The '''mozFrameBuffer''' attribute contains the raw audio data (float values) obtained from decoding a single frame of audio.
