libassp иии Advanced Speech Signal Processor
Project at
tclassp Documentation
The assp (advanced speech signal processor) library aims at providing functionality for handling speech signal files in most common audio formats and for performing analyses common in phonetic science/speech science. These will include the calculation of formants, fundamental frequency, root mean square, auto correlation, a variety of spectral analyses, zero crossing rate, filtering etc.

Currently, we plan to use this library for command line tools and for a Tcl-Extension. The latter will be usefull for eg. the Emu Speech Database System, which so far relies on non-library commandline tools. For the future, a reimplementation of xassp using libassp is also possible.
