No. I might try that next time, but I have a feeling it would make a long p=
rocess more fatiguing.

s. I skip though, playing short selections with special attention to any vi=
sual cues for new sounds or changing dynamics. When I find noteworthy secti=
ons, I listen while writing a description with time position and duration r=
eferences in a separate textual file, and then begin skipping forward ahead=
 again to find the next noteworthy section. An hour of recording might take=
 fifteen or twenty minutes to skim this way. When I am done I can go throug=
h my notes and return to pertinent sections with more scrutiny. I often hav=
e more than 16 hours of material to review from a weekend recording trip.
