I would like to see what the real raw data looks like. There doesn't look to be any noise in that wiggle plot and the signal has already been processed to a degree (see the hard edges and squareness of the features). That's really the hard part though, going from raw to digital, and the decisions that are made regarding how that transformation is achieved will have a lot to do with the quality of the data.
