From f5a3e61e69af1c030aec87b6e23660a526640f2d Mon Sep 17 00:00:00 2001 From: Sebastian Dröge Date: Thu, 6 Sep 2007 07:21:22 +0000 Subject: Port GstSpectrum to GstAudioFilter and libgstfft, add support for int32, float and double, use floats for the message... Original commit message from CVS: * configure.ac: * gst/spectrum/Makefile.am: * gst/spectrum/demo-audiotest.c: (draw_spectrum), (message_handler), (main): * gst/spectrum/demo-osssrc.c: (draw_spectrum), (message_handler): * gst/spectrum/gstspectrum.c: (gst_spectrum_base_init), (gst_spectrum_class_init), (gst_spectrum_init), (gst_spectrum_dispose), (gst_spectrum_set_property), (gst_spectrum_get_property), (gst_spectrum_start), (gst_spectrum_setup), (gst_spectrum_message_new), (gst_spectrum_transform_ip): * gst/spectrum/gstspectrum.h: Port GstSpectrum to GstAudioFilter and libgstfft, add support for int32, float and double, use floats for the message contents, average all FFTs done in one interval for better results, use a better windowing function, allow posting the phase in the message and actually do an FFT with the requested number of bands instead of interpolating. * tests/check/elements/spectrum.c: (GST_START_TEST), (spectrum_suite): Improve the units tests by checking for a 11025Hz sine wave and add unit tests for all 4 supported sample types. --- gst/spectrum/Makefile.am | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'gst/spectrum/Makefile.am') diff --git a/gst/spectrum/Makefile.am b/gst/spectrum/Makefile.am index db66dd6c..e161abbf 100644 --- a/gst/spectrum/Makefile.am +++ b/gst/spectrum/Makefile.am @@ -1,10 +1,10 @@ plugin_LTLIBRARIES = libgstspectrum.la -libgstspectrum_la_SOURCES = gstspectrum.c fix_fft.c +libgstspectrum_la_SOURCES = gstspectrum.c libgstspectrum_la_CFLAGS = $(GST_PLUGINS_BASE_CFLAGS) $(GST_BASE_CFLAGS) \ $(GST_CFLAGS) -libgstspectrum_la_LIBADD = $(GST_PLUGINS_BASE_LIBS) $(GST_BASE_LIBS) $(GST_LIBS) +libgstspectrum_la_LIBADD = $(GST_PLUGINS_BASE_LIBS) $(GST_BASE_LIBS) $(GST_LIBS) -lgstaudio-$(GST_MAJORMINOR) -lgstfft-$(GST_MAJORMINOR) $(LIBM) libgstspectrum_la_LDFLAGS = $(GST_PLUGIN_LDFLAGS) noinst_HEADERS = gstspectrum.h -- cgit
