"Your author has used Cinelerra in the past for audio editing,
see this article for details. Cinelerra has one capability that is
hard to find in other Linux audio editing software, the ability to
split (render) a huge .wav file into a group of smaller .wav files
across multiple position labels, all in one operation. This feature
is useful for processing long audio recordings such as digitized
vinyl album sides and copies of digital audio (DAT) tapes."
