sox lpc10 license

[Frantisek Kluknavsky]

Hi list,

package sox contains bundled lpc10 library. License of lpc10 is unknown 
to me and unknown to sox upstream. Probably nobody (probably including 
lpc10 authors) bothered too much about licensing.

My questions:
  - Does anyone know its licensing status or original developers? Andy 
J. Fingerhut, previously associated with wustl.edu?

  - Does any package strictly require lpc10 functionality (linear 
predictive voice coder)? Can I tear it out of sox?

  - Can the whole issue be ignored?

  - Does Fedora contain other implementations of lpc10?

Thank you very much.
