class MatrixRec(PyoObject):
"""
MatrixRec records samples into a previously created NewMatrix.
See :py:class:`NewMatrix` to create an empty matrix.
The play method is not called at the object creation time. It starts
the recording into the matrix, row after row, until the matrix is full.
Calling the play method again restarts the recording and overwrites
previously recorded samples. The stop method stops the recording.
Otherwise, the default behaviour is to record through the end of the matrix.
:Parent: :py:class:`PyoObject`
:Args:
input : PyoObject
Audio signal to write in the matrix.
matrix : PyoMatrixObject
The matrix where to write samples.
fadetime : float, optional
Fade time at the beginning and the end of the recording
in seconds. Defaults to 0.
delay : int, optional
Delay time, in samples, before the recording begins.
Available at initialization time only. Defaults to 0.
.. note::
The out() method is bypassed. MatrixRec returns no signal.
MatrixRec has no `mul` and `add` attributes.
MatrixRec will sends a trigger signal at the end of the recording.
User can retreive the trigger streams by calling obj['trig']. See
`TableRec` documentation for an example.
