Instance Method Detail
Writes sample data to an output stream. This function doesn't return until the entire buffer has been consumed - this may involve waiting for the operating system to consume the data. The size of the data must be equal to the frames per buffer multiplied by the number of output channels.
This returns self.

Terminates audio processing immediately without waiting for pending buffers to complete.
Attempts to read samples from an input stream into the destination. The method doesn't return until the entire buffer has been filled - this may involve waiting for the operating system to supply the data.
The size of the destination must be less than or equal to the number of frames per buffer multiplied by the channel count.
On success, this returns true. If input data was discarded by PortAudio
after the previous call and before this call, this returns false.
Otherwise this will raise a PaError if another error occurs.
Attempts to read samples from an input stream. The method doesn't return until one entire buffer has been filled - this may involve waiting for the operating system to supply the data. The size of returned data equal to the number of frames per buffer multiplied by the channel count.
On success, this returns the batch of data. Otherwise this will raise a
PaError if another error occurs.
