I now have this in my callback function:
short* data = oframe->data[0];
for (int i = 0; i < oframe->nb_samples; ++i) {
//divide by SHRT_MAX to transform into double between 0 and 1
_outBuffer[i] = (double) data[i] / (double) SHRT_MAX;
}
It seems fine in respect to the final result and its similarity to those
obtained with other "audio extraction methods".
Can somebody just confirms that i'm not doing dumb conversion?
thanks
Florian
