there are a couple of major problems in implementing this:

  - this would have to be done in an audio plugin (as this
    is not real-time and has to be behind a buffer)
  - there is currently way to sends commands to audio
    plugins during processing

... but, but, would a simpler interface do? Maybe something like:

ecasound -i alsa -o timesplit,60,foo-%d.wav

Would start recording to foo-0.wav and after 60secs, it would switch to
foo-1.wav, and so on. Ideas w.r.t. syntax and possible params are welcome.

This something that could be implemented by adding a new plugin (versus
having to make changes in core functionality which is always much more
riskier and time consuming).
