I just uploaded a new track,
here.
The overall quality of this track seems the best I've done yet; there are only a few noticeable flubs, and the consistency of the lines is getting better. Getting closer to something perhaps worth putting on a CD.
The raw recording was done on my new Zoom R16. I used Audacity to take out line noise and to set the beginning and end, including the fade out, and to also raise the level of the track to a 0db ceiling.
