I have a question on the length of the audio buffer.
I open the audio with the following parameters
SDL_AudioSpec desired, obtained;
desired.freq = 44100;
desired.format = AUDIO_S16;
desired.samples = 4096;
desired.channels = 2;
desired.callback = AudioCallback;
desired.userdata = NULL;
if (SDL_OpenAudio(&desired, &obtained) < 0) {
printf("Unable to open audio device: %s\n", SDL_GetError());
return 1;
}
after the last call i got obtained.samples = 4096;
Now, I expect that 4096 is the length of the audio buffer but in the audio callback I got length=16348.
My question is: which is the relationship between obtained.samples and length ?
is length = 4 * obtained.samples or the length of the AudioCallback depends on the Hardware or the SO ?
Thanx,
Stefano Manzella
