Function Documentation

◆ aubio_sampler_do()

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

process sampler function

Parameters
osampler, created by new_aubio_sampler()
inputinput of the sampler, to be added to the output
outputoutput 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
osampler, created by new_aubio_sampler()
inputinput of the sampler, to be added to the output
outputoutput 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()

uint_t aubio_sampler_get_playing ( const aubio_sampler_t o)

get current playing state

Parameters
osampler, created by new_aubio_sampler()
Returns
0 if not playing, 1 if playing

◆ aubio_sampler_load()

uint_t aubio_sampler_load ( aubio_sampler_t o,
const char_t uri 
)

load source in sampler

Parameters
osampler, created by new_aubio_sampler()
urithe 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)

play sample from start

Parameters
osampler, created by new_aubio_sampler()
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
osampler, created by new_aubio_sampler()
playing0 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
osampler, 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
osampler, 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
sampleratethe sampling rate of the new sampler
hop_sizethe block size of the new sampler
Returns
the newly created aubio_sampler_t
Examples:
synth/test-sampler.c.
