    Recording audio is a real-time operation, so if your code doesn’t call read() quickly enough, some audio will be lost. To warn about this, read() will throw an exception if audio data is dropped.

    Warning

    Recording audio is a real-time operation, so if your code doesn’t call read() quickly enough, some audio will be lost. To warn about this, read() will throw an exception if audio data is dropped. This behavior can be disabled by setting ignore_dropped_input to True. The number of dropped samples since the last call to read() can be retrieved by accessing the dropped_input_frame_count property.
