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 only duration:Float

Returns a double representing the duration, in seconds, of the PCM data stored in the buffer.

read only length:Int

Returns an integer representing the length, in sample-frames, of the PCM data stored in the buffer.

read only numberOfChannels:Int

Returns an integer representing the number of discrete audio channels described by the PCM data stored in the buffer.

read only sampleRate:Float

Returns a float representing the sample rate, in samples per second, of the PCM data stored in the buffer.
