GstAudioQuantize

GstAudioQuantize

Includes

#include <gst/audio/audio.h>

Description

Functions

gst_audio_quantize_free ()

void
gst_audio_quantize_free (GstAudioQuantize *quant);

Free a GstAudioQuantize.

Parameters

quant

a GstAudioQuantize

 

gst_audio_quantize_new ()

GstAudioQuantize *
gst_audio_quantize_new (GstAudioDitherMethod dither,
                        GstAudioNoiseShapingMethod ns,
                        GstAudioQuantizeFlags flags,
                        GstAudioFormat format,
                        guint channels,
                        guint quantizer);

gst_audio_quantize_samples ()

void
gst_audio_quantize_samples (GstAudioQuantize *quant,
                            const gpointer in[],
                            gpointer out[],
                            guint samples);

Perform quantization on samples in in and write the result to out .

In case the samples are interleaved, in and out must point to an array with a single element pointing to a block of interleaved samples.

If non-interleaved samples are used, in and out must point to an array with pointers to memory blocks, one for each channel.

in and out may point to the same memory location, in which case samples will be modified in-place.

Parameters

quant

a GstAudioQuantize

 

in

input samples

 

out

output samples

 

samples

number of samples

 

gst_audio_quantize_reset ()

void
gst_audio_quantize_reset (GstAudioQuantize *quant);

Reset quant to the state is was when created, clearing any history it might have.

Parameters

quant

a GstAudioQuantize
