Subject: [PATCH] splitfx: pass compression factor to sox(1)
Date: Sun, 10 May 2015 11:23:11 +0000	[thread overview]
Message-ID: <1431256991-18671-1-git-send-email-e@80x24.org> (raw)

This can be useful for speeding up splitfx during development,
as sox defaults to maximum compression with FLAC and that is
extremely slow.
