From 76a3fd7100246d47d3dcf08cd1e3370adca244af Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Sebastian=20Dr=C3=B6ge?= 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. --- ChangeLog | 26 ++++++++++++++++++++++++++ 1 file changed, 26 insertions(+) (limited to 'ChangeLog') diff --git a/ChangeLog b/ChangeLog index 50e475a0..203b487a 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,29 @@ +2007-09-06 Sebastian Dröge + + * 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. + 2007-09-05 Wim Taymans * gst/real/gstrealvideodec.c: (gst_real_video_dec_chain), -- cgit v1.2.1
