|
|
An array of 64-bit double precision floating point numbers.
|
||
|
|
|
||
|
|
Note that despite not having "Float" in its name, DoubleArray does in fact hold
|
||
|
|
a sequence of SuperCollider double precision link::Classes/Float##floats::.
|
||
|
|
For a raw array of 32-bit floats, use link::Classes/FloatArray::.
|
||
|
|
|
||
|
|
FloatArray and its subclass link::Classes/Signal:: are commonly used to hold
|
||
|
|
audio data in SuperCollider. Since almost all audio has 16-bit or 24-bit
|
||
|
|
precision, using double precision floats for this purpose would be a waste of
|
||
|
|
space. In other words, use FloatArray for audio, and DoubleArray for precise
|
||
|
|
math operations.
|
||
|
|
|
||
|
|
The complete list of RawArray types in SuperCollider is:
