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

void aubio_sampler_do	(	aubio_sampler_t *	o,
		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.

void aubio_sampler_do_multi	(	aubio_sampler_t *	o,
		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.

uint_t aubio_sampler_get_playing

(

aubio_sampler_t *

o

)

get current playing state

Parameters

o	sampler, created by new_aubio_sampler()

Returns

0 if not playing, 1 if playing

uint_t aubio_sampler_load	(	aubio_sampler_t *	o,
		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.

uint_t aubio_sampler_play

(

aubio_sampler_t *

o

)

play sample from start

Parameters

o	sampler, created by new_aubio_sampler()

Returns

0 if successful, 1 otherwise

Examples:

synth/test-sampler.c.

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

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.

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.

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:

synth/test-sampler.c.
