AudioBuffer interface represents a short audio asset residing in memory, created from an audio file using the
AudioContext.decodeAudioData() method, or from raw data using
AudioContext.createBuffer(). Once put into an AudioBuffer, the audio can then be played by being passed into an
Objects of these types are designed to hold small audio snippets, typically less than 45 s. For longer sounds, objects implementing the
MediaElementAudioSourceNode are more suitable. The buffer contains the audio signal waveform encoded as a series of amplitudes in the following format: non-interleaved IEEE754 32-bit linear PCM with a nominal range between
+1, that is, a 32-bit floating point buffer, with each sample between -1.0 and 1.0. If the
AudioBuffer has multiple channels, they are stored in separate buffers.
