gst_audio_quantize_reset 

gst_audio_quantize_reset (GstAudioQuantize * quant)

a GstAudioQuantize

GstAudio.AudioQuantize.prototype.reset 

function GstAudio.AudioQuantize.prototype.reset(): {
    // javascript wrapper for 'gst_audio_quantize_reset'
}

Parameters:

a GstAudio.AudioQuantize

GstAudio.AudioQuantize.reset 

def GstAudio.AudioQuantize.reset (self):
    #python wrapper for 'gst_audio_quantize_reset'

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

Parameters:

a GstAudio.AudioQuantize

gst_audio_quantize_samples 

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

GstAudio.AudioQuantize.prototype.samples 

function GstAudio.AudioQuantize.prototype.samples(in: Object, out: Object, samples: Number): {
    // javascript wrapper for 'gst_audio_quantize_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:

a GstAudio.AudioQuantize

in (Object) –

input samples

out (Object) –

output samples

samples (Number) –

number of samples

GstAudio.AudioQuantize.samples 

def GstAudio.AudioQuantize.samples (self, in, out, samples):
    #python wrapper for 'gst_audio_quantize_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:

a GstAudio.AudioQuantize

in (object) –

input samples

out (object) –

output samples

samples (int) –

number of samples

Functions

gst_audio_quantize_new 

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

Create a new quantizer object with the given parameters.

Output samples will be quantized to a multiple of quantizer. Better performance is achieved when quantizer is a power of 2.

Dithering and noise-shaping can be performed during quantization with the dither and ns parameters.

Parameters:

dither –

a GstAudioDitherMethod

ns –

a GstAudioNoiseShapingMethod

flags –

GstAudioQuantizeFlags

format –

the GstAudioFormat of the samples

channels –

the amount of channels in the samples

quantizer –

the quantizer to use

Returns –

a new GstAudioQuantize. Free with gst_audio_quantize_free.
