*global gain and scalefactors:How is the scaling done?Is the scaling done by (global gain * scalefactor) or by (global gain - scalefactor)?
*scaling:What is scaled, signal or quantizer step size?
I think that I am still missing a part:let's call ix the mdct output signal (floating point), do we quantize:actual_local_sf * ix ? (of course actual_local_sf is varying between sf bands)
QuantSignal[w] = NINT( pow( ix[w] / actual_local_sf, 0.75 ) - 0.0946 )
It seems to me that by increasing the scale_factor (so decreasing the global scale value) the signal is not really amplified but less devided.Overall it is equivalent, but still strange.
