1.
If any of the values in {{AudioBuffer/constructor()/options!!argument}} lie outside its nominal range, throw a {{NotSupportedError}} exception and abort the following steps.
- 1. Let
b be a new {{AudioBuffer}} object.
- 1. Respectively assign the values of the attributes
+ 1. Respectively assign the values of the members
{{AudioBufferOptions/numberOfChannels}}, {{AudioBufferOptions/length}},
- {{AudioBufferOptions/sampleRate}} of the {{AudioBufferOptions}} passed
- in the constructor to the internal slots {{[[number of channels]]}}, {{[[length]]}}, {{[[sample rate]]}}.
+ {{AudioBufferOptions/sampleRate}} of {{AudioBuffer/constructor()/options!!argument}}
+ to [=this=]'s internal slots {{[[number of channels]]}}, {{[[length]]}}, {{[[sample rate]]}}.
- 1. Set the internal slot {{[[internal data]]}} of this
- {{AudioBuffer}} to the result of calling
- CreateByteDataBlock({{[[length]]}} * {{[[number of channels]]}}).
+ 1. Set [=this=]'s {{[[internal data]]}} to the result of calling
+
+ CreateByteDataBlock({{[[length]]}} * {{[[number of channels]]}} * 4).
- Note: This initializes the underlying storage to zero.
-
- 1. Return
b.
+ Note: This initializes the underlying storage to zero. Each
+ sample is a 32-bit float, i.e. 4 bytes.
