I have some live concert recordings (some destined for LMA) which
could use some processing in certain sections (usually to cut out crowd
noise and AC hum).
The recordings are hours long, but I only want to selectively process
some portions (often sections inbetween music).
So far, I've been writing scripts+makefiles to drive SoX. I use
the SoX "trim" effect to split out sections, process the sections
indivdually, and rejoin them (often with fade); but I'm wondering if
there's something similar for command-line users which already exists.
I've been considering writing a make-like tool, but would like know if
something existing fills the role. I haven't been able to find
information on using csound for mastering a few sections of audio, but
maybe that could work...
I don't like pointing devices, so it must be 100% keyboard-driven and
easily repeatable/version-controlled. I manage my current
scripts+makefiles via git.
