Re: Hi Ted.

Howdy

Have you read all of my responses on this thread?

You don't have to wait for the peak. Look at the waveform that Cool Edit Pro displayed. The program had no idea what I gave it. Here's what I gave it:


#include

#define _USE_MATH_DEFINES
#include

int main () {
const double sr = 44100;
const double sp = 1/sr;
FILE * h = fopen("out.pcm", "w");
for (double t = 0; t < 1; t += sp) {
double a = sin(t * (M_PI * 2) * (sr / (44000.0l/14000)));
short s = int(a * 32767);
fwrite(&s, 2, 1, h); }
fclose(h); }

Cool Edit Pro (and your DAC) have no idea what waveform I gave, but the peak is reconstructed accurately from the samples present.

Anyway go listen to your 14kHz sampled and reconstructed at 32k, 44.1k, 48k, 96k, etc. They all sound the same to my ears and have the same amplitude. It also agrees with theory. Why would I believe yours eyes instead of mine and my ears and the theory?
