Supported sample formats are int16, int32, float and double. For those formats a real FFT and IFFT can be done, different windowing functions can be applied and functions for extracting the magnitude and phase exist. Fixes #468619. * docs/libs/Makefile.am: * docs/libs/gst-plugins-base-libs-docs.sgml: * docs/libs/gst-plugins-base-libs-sections.txt: Integrate libgstfft into the docs. * tests/check/Makefile.am: * tests/check/libs/fft.c: (GST_START_TEST), (fft_suite), (main): Add unit tests for libgstfft, currently only testing the FFT. Unit tests for IFFT will follow soon.		2007-09-06 07:00:36 +00:00
