wrassp is a wrapper for R around Michel Scheffers's libassp (Advanced Speech Signal Processor). The libassp 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. This includes the calculation of formants, fundamental frequency, root mean square, auto correlation, a variety of spectral analyses, zero crossing rate, filtering etc. This wrapper provides R with a large subset of libassp's signal processing functions and provides them to the user in a (hopefully) user-friendly manner. The wrassp package is used by the EMU Speech Database Management System (EMU-SDMS) to perform signal processing routines.
When calling get.trackdata on a large data object, the memory is running out pretty quickly. An example is found under linux22:/tmp/deutschHeuteMemoryLeak with the R commands used in rCommands.r (works when the working directory is set to the directory where the RData objects are saved).
This is a memory leak issue of performAssp(). 9352527a3393 should fix this issue! @thomaskisler please rerun on your data. On the softlink version of your DB it seems to now work on my mac...
