IPS-LMU / wrassp

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.

parameter testing #21

Closed raphywink closed 9 years ago

raphywink commented 11 years ago

test_that("acfana doesn't brake due to varying parameters", {... test in test_signalProc.R sometimes fails. This is due to 'COS' not being a valid window type for acfana. Does that mean not every WindowType returned by AsspWindowTypes() is valid for every function that takes a WindowType as an argument?

Furthermore I would need more infos about possible parameter values (except for the obvious of course) for every signal proc. func.. Then I'll we can generate several parameters sets at random to see if we can break the functions.

same goes for test_that("cepstrum doesn't brake due to varying parameters", { test. 'COS' WindowType causes R to crash.
