Description
|
|
•
|
The Extract command extracts a piece of an audio recording and returns a new audio object containing the extracted piece.
|
•
|
The audArray parameter must be a dense, rectangular, one or two dimensional Array, Vector, or Matrix with datatype=float[8].
|
•
|
The timeRange parameter can be either a number, or a range of numbers. In either case, positive values refer to times relative to the beginning of audArray, whereas negative values refer to times relative to the end of audArray.
|
|
If a number is specified, Extract extracts that many seconds from the beginning (if positive) or end (if negative) of audArray.
|
|
If a range is specified, the data between those two points in time is extracted. Negative values are treated as described above.
|
•
|
Because Extract can only work to the nearest whole sample, the precise duration of the result may be slightly more or less than what was specified by timeRange.
