execute method
Computes the non-redundant complex spectrum of a real-valued input frame.
Example:
final z = plan.execute(frame);
print('DC = ${z.realAt(0)}');
Implementation
Complex32List execute(Float32List input) {
final r = res;
_loadInput(input);
yl_fft_plan_execute_r2c(r.plan, r.input, r.re, r.im);
re.setAll(0, r.re.asTypedList(bins));
im.setAll(0, r.im.asTypedList(bins));
return Complex32List.wrap(re, im);
}
