*
* Audioconvert converts raw audio buffers between various possible formats.
* It supports integer to float conversion, width/depth conversion,
* signedness and endianness conversion and channel transformations
* (ie. upmixing and downmixing), as well as dithering and noise-shaping.

* The vorbis encoder takes float audio data instead of the integer data
* output by most other audio elements. This pipeline decodes a FLAC audio file
* (or any other audio file for which decoders are installed) and re-encodes
* it into an Ogg/Vorbis audio file.
*
* A mix matrix can be passed to audioconvert, that will govern the
* remapping of input to output channels.
* ## Example matrix generation code
* To generate the matrix using code:
*
* |[
* GValue v = G_VALUE_INIT;
* GValue v2 = G_VALUE_INIT;
* GValue v3 = G_VALUE_INIT;
*
* g_value_init (&v2, GST_TYPE_ARRAY);
* g_value_init (&v3, G_TYPE_FLOAT);
* g_value_set_float (&v3, 1);
* gst_value_array_append_value (&v2, &v3);
* g_value_unset (&v3);
* [ Repeat for as many float as your input channels - unset and reinit v3 ]
* g_value_init (&v, GST_TYPE_ARRAY);
* gst_value_array_append_value (&v, &v2);
* g_value_unset (&v2);
* [ Repeat for as many v2's as your output channels - unset and reinit v2]

gst/audioconvert/: Implement dithering and noise shaping in audioconvert. By default now Original commit message from CVS: * gst/audioconvert/Makefile.am: * gst/audioconvert/audioconvert.c: (audio_convert_get_func_index), (check_default), (audio_convert_prepare_context), (audio_convert_clean_context), (audio_convert_convert): * gst/audioconvert/audioconvert.h: * gst/audioconvert/gstaudioconvert.c: (gst_audio_convert_dithering_get_type), (gst_audio_convert_ns_get_type), (gst_audio_convert_class_init), (gst_audio_convert_init), (gst_audio_convert_set_caps), (gst_audio_convert_set_property), (gst_audio_convert_get_property): * gst/audioconvert/gstaudioconvert.h: * gst/audioconvert/gstaudioquantize.c: (gst_audio_quantize_setup_noise_shaping), (gst_audio_quantize_free_noise_shaping), (gst_audio_quantize_setup_dither), (gst_audio_quantize_free_dither), (gst_audio_quantize_setup_quantize_func), (gst_audio_quantize_setup), (gst_audio_quantize_free): * gst/audioconvert/gstaudioquantize.h: Implement dithering and noise shaping in audioconvert. By default now TPDF dithering (and no noise shaping) will be used when converting from a higher bit depth to 20 bit depth or smaller, otherwise everything will be as it is now. For the last audioconvert in a pipeline it would make sense to use some kind of noise shaping, enabling it by default for all conversions would give undesired results though. Fixes #360246. * tests/check/elements/audioconvert.c: (setup_audioconvert), (GST_START_TEST): Adjust unit test for the new audioconvert.
