Detailed Description

Load and play sound files.

This file loads a sample and gets ready to play it.

The _do function adds the new samples to the input, and write the result as the output.

Function Documentation

aubio_sampler_do()

void aubio_sampler_do	(	aubio_sampler_t *	o,
		const fvec_t *	input,
		fvec_t *	output
	)

process sampler function

Parameters

o	sampler, created by new_aubio_sampler()
input	input of the sampler, to be added to the output
output	output of the sampler

This function adds the new samples from the playing source to the output.

If input is not NULL and different from output, then the samples from input are added to the output.

Examples

synth/test-sampler.c.

aubio_sampler_do_multi()

void aubio_sampler_do_multi	(	aubio_sampler_t *	o,
		const fmat_t *	input,
		fmat_t *	output
	)

process sampler function, multiple channels

Parameters

o	sampler, created by new_aubio_sampler()
input	input of the sampler, to be added to the output
output	output of the sampler

This function adds the new samples from the playing source to the output.

If input is not NULL and different from output, then the samples from input are added to the output.

aubio_sampler_get_playing()

aubio_sampler_load()

uint_t aubio_sampler_load	(	aubio_sampler_t *	o,
		const char_t *	uri
	)

load source in sampler

Parameters

o	sampler, created by new_aubio_sampler()
uri	the uri of the source to load

Returns

0 if successful, non-zero otherwise

Examples

synth/test-sampler.c.

aubio_sampler_play()

uint_t aubio_sampler_play

(

aubio_sampler_t *

o

Returns

0 if successful, 1 otherwise

Examples

synth/test-sampler.c.

aubio_sampler_set_playing()

uint_t aubio_sampler_set_playing	(	aubio_sampler_t *	o,
		uint_t	playing
	)

set current playing state

Parameters

o	sampler, created by new_aubio_sampler()
playing	0 for not playing, 1 for playing

Returns

0 if successful, 1 otherwise

aubio_sampler_stop()

uint_t aubio_sampler_stop

(

aubio_sampler_t *

o

)

stop sample

Parameters

o	sampler, created by new_aubio_sampler()

Returns

0 if successful, 1 otherwise

Examples

synth/test-sampler.c.

del_aubio_sampler()

void del_aubio_sampler

(

aubio_sampler_t *

o

)

destroy aubio_sampler_t object

Parameters

o	sampler, created by new_aubio_sampler()

Examples

synth/test-sampler.c.

new_aubio_sampler()

aubio_sampler_t * new_aubio_sampler	(	uint_t	samplerate,
		uint_t	hop_size
	)

create new sampler object

Parameters

samplerate	the sampling rate of the new sampler
hop_size	the block size of the new sampler

Returns

the newly created aubio_sampler_t

Examples
