Consider using LPC instead of LPC10 #7

The HawkVoice Direct Interface offers multiple other codecs. They have LPC, OPENLPC, LPC10, and CELP.

The LPC codec seems to have better voice quality while operating at the same bitrate as LPC10.

Maybe you can try using LPC instead of LPC10?

The LPC codec also has fewer and smaller code files.

This was already started some time ago, but the data structures for the LPC codec are different to LPC10, and so far I haven't been able to get it working.

If LPC can be made to work with EasyDRF it will be a useful improvement.
