al_create_sample (3alleg5)

• #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)
  
  

Create a sample data structure from the supplied buffer. If free_buf is true then the buffer will be freed with al_free(3alleg5) when the sample data structure is destroyed. For portability (especially Windows), the buffer should have been allocated with al_malloc(3alleg5). Otherwise you should free the sample data yourself.

To allocate a buffer of the correct size, you can use something like this:

• sample_size = al_get_channel_count(chan_conf) * al_get_audio_depth_size(depth);
  bytes = samples * sample_size;
  buffer = al_malloc(bytes);
