This is a very poor recording.
Most sentences are not intelligible.
The volume is too low, there are noises of someone holding the mic,
and noises from the audience coughing. There is a distortion due to too
much distance from speaker to his mic, like in a barrell.
All of this can be fixed by using a REMOTE MICROPHONE. Keep the mic
within 2 feet, and the recorder can be 20 feet away, no problem.
