Hello, I have two questions concerning floor1 encoding/decoding. First I'll ask about the FLOOR1_fromdB_LOOKUP table: what is it's purpose? Is it to convert the amplitude differences between [floor1_Y] values to a dB scale? And, if I'm right with that, here comes the 2nd question: when render_line0 is used to encode floor1, then floor1_inverse2 must be used in decode (in order to convert to dB scale), and, in the other hand, if render_line is used to encode, then floor1_inverse1 must be used in decode (render_line converts to dB and therefore floor1_inverse1 gets the amplitudes in dB). If all...
