Tools and documentation
A manual for calibration of hearing aid output was added. Octave/Matlab tools to generate an openMHA configuration according to the outcome of the calibration procedure as well as an configuration example for testing the calibration are provided.
The openMHA documentation has been updated following user feedback. In particular the hands-on example in section 4 of the application engineer manual has been simplified.

The addsndfile allows to mix sound from a file to a live audio signal.
