If phase is float, calculations in impl_native_in_len/out_len don't
necessarily match with do_resample, because e.g.
float phase0 = 7999.99;
float phase = phase0;
int frac = 8000, out_rate = 8000, n = 64, count = 0;
for (int j = 0; j < n; ++j) {
phase += frac;
if (phase >= out_rate) {
phase -= out_rate;
count++;
}
}
printf("count = %d\n", count); /* count = 64 */
count = (int)(phase0 + n*frac) / out_rate;
printf("count = %d\n", count); /* count = 65 */
don't give the same result.
Also add test where floating point multiplication rounding up to nearest
in
float ph = phase * pm;
uint32_t offset = (uint32_t)floorf(ph);
computation results to offset+1 > data->n_phases, accessing filter array
beyond bounds. (The accessed value is still inside allocated memory
block, but contains unrelated values; the test passes silently.)
