PyoObjects to perform operations on PyoMatrixObjects.

PyoMatrixObjects are 2 dimensions table containers. They can be used
to store audio samples or algorithmic sequences. Writing and reading
are done by giving row and column positions.

[docs]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.
