[Freeswitch-dev] How to get value of the sample?

[Anthony Minessale]

Not enough to go on from that ....

You probably want something more like.


{
int16_t *samples = (int16_t *) frame->data;
int x = 0;

for (x = 0; x < frame->datalen / 2; x++) {
   printf("[%d] ", samples[x]);
}

printf("\n\n");

}
