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 data in the following format: non-interleaved IEEE754 32-bit linear PCM with a nominal range between -1
and +1
, that is, 32bits floating point buffer, with each samples between -1.0 and 1.0. If the AudioBuffer
has multiple channels, they are stored in separate buffer.

Variables
read onlynumberOfChannels:Int
Returns an integer representing the number of discrete audio channels described by the PCM data stored in the buffer.
read onlysampleRate:Float
Returns a float representing the sample rate, in samples per second, of the PCM data stored in the buffer.
