Subject: [PATCH] splitfx: add "offset" option for all track times
Date: Sun, 17 Nov 2019 22:47:20 +0000 [thread overview]
Message-ID: <20191117224720.7361-1-e@80x24.org> (raw)
This option is intended to make it easy to reuse track splits
from one audio recording of a given source (e.g. a live
performance or vinyl rip) for another audio recording of
the same source.
