Somewhat... but personally, I would not do this:

  Script it by using "dtas-ctl source ed ..." based on using the
  "watch" command in the protocol.  Sorry, there isn't a
  command-line tool specifically for using "watch", but
  dtas-console uses it.

  Here's a bit of Ruby that should work:

    require 'dtas/unix_client'
    c = DTAS::UNIXClient.new
    c.req('watch')
    while res = c.res_wait
      p res
      # do something with res
    end

...Instead, I use splitfx YAML files like:

  https://dtas.80x24.org/examples/splitfx.sample.yml

I like having files around which I can save/edit and store in
version control rather than ephemeral commands which are more
easily lost.

I edit the "command" section as needed.  It could even
be a standalone script/command for processing[1] since
big sox commands get ugly in YAML.

You may remove the "tracks" section for playback.

[1] I have some gnarly Ruby scripts for some files and am
    working on libifying some of it.
