Float32Arraycontaining 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).

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
