I used to do the same when scanning the music collections of friends. You can
establish pretty quickly whether there is something interesting in a track or
not. Just skip, listen, skip, listen. With long nature recordings I tend to go
to 4x speed and then slow down to normal speed (reversing for a few seconds) if
I find something that I think might be of interest. I do all that while looking
at the spectrogram so I usually see where the interesting bit was and can
quickly go back to that position. It is, however, still a manual process ...
The other option would be to crowdsource the recordings - put everything on
Soundcloud unedited and ask people to comment on the sections that they like.
That way you'd have a pre-selection of the sections that people actually like.
You'd need a lot of dedicated and loyal followers though and it wouldn't ensure
that what you think is good would end up on an album ...
Cheers,
Eric
