It's too pity sound quality is poor.
Her microphone should closer to her and eliminate echo.
Thank you Intersil for making this effort in creating these clips.
The recording was done in a "hard room" with no sound absorption, so it bounces and echoes a lot. Please consider buying a countryman microphone (I have no relationship to the company). This type of mic sits on the ear and puts the tiny mic right by the mouth, which can definitely help compensate for a room with no audio baffles. These mics were superb in classrooms. We also had people trained for camera work so that the zoom in and out was more seamless.
Please consider this as constructive feedback and I hope your company continues to make these clips.
Kudos to Intersil for coming up with the DCP product which can withstand 125 deg C temperatures. Heather did a good job of presenting the product, it is no fault of hers that the audio could have been better handled with a little bit of professional help.
