al_create_sample - Allegro 5 API

SYNOPSIS

C]
#include <allegro5/allegro_audio.h>

ALLEGRO_SAMPLE *al_create_sample(void *buf, unsigned int samples, unsigned int freq, ALLEGRO_AUDIO_DEPTH depth, ALLEGRO_CHANNEL_CONF chan_conf, bool free_buf) ]

DESCRIPTION

Create a sample data structure from the supplied buffer. If C]free_buf] is true then the buffer will be freed with al_free(3) when the sample data structure is destroyed. For portability (especially Windows), the buffer should have been allocated with al_malloc(3). Otherwise you should free the sample data yourself.

To allocate a buffer of the correct size, you can use something like this:
C]
sample_size = al_get_channel_count(chan_conf) * al_get_audio_depth_size(depth);
bytes = samples * sample_size;
buffer = al_malloc(bytes);
]
