Original commit message from CVS: * gst/audiofx/audiochebyshevfreqband.c: (gst_audio_chebyshev_freq_band_class_init): * gst/audiofx/audiochebyshevfreqlimit.c: (gst_audio_chebyshev_freq_limit_class_init): Use generator macros for the process functions for the different sample types, add lower upper boundaries for the GObject properties so automatically generated UIs can use sliders and add a note about the number of poles as a too high number of poles combined with very low or very high frequencies will produce only noise. * docs/plugins/gst-plugins-good-plugins.args: Regenerated for the property changes.

(gst_audio_chebyshev_freq_band_class_init):
|
||||
* gst/audiofx/audiochebyshevfreqlimit.c:
|
||||
(gst_audio_chebyshev_freq_limit_class_init):
|
||||
Use generator macros for the process functions for the different
|
||||
sample types, add lower upper boundaries for the GObject properties
|
||||
so automatically generated UIs can use sliders and add a note about
|
||||
the number of poles as a too high number of poles combined with
|
||||
very low or very high frequencies will produce only noise.

Regenerated for the property changes.
