walker7 Posted May 30, 2015 Share Posted May 30, 2015 (edited) Can someone clearly explain the bit pattern for TIA audio distortions 2 and 3? This is what I know so far: Distortion 2: 001010000111011->0100000000000000000100000000000 (465 bits long)Distortion 3: 001010000111011->0010110011111000110111010100001 (465 bits long) These are named "DIV31_POLY4" and "POLY5_POLY4" in the tiasound.c document. <http://web.archive.org/web/20120705120940/http://mamedev.org/source/src/emu/sound/tiasound.c> What exactly is going on here? Also, I noticed that distortion 11 is called "POLY5_POLY5", even though it makes no sound (same as distortion 0). Any reason that name was chosen? The only reason I can think of is that it matches up with distortions 2, 3, and 10: 2 = "DIV31_POLY4" 3 = "POLY5_POLY4" 10 = "DIV31_POLY5" 11 = "POLY5_POLY5" Edited May 30, 2015 by walker7 Quote Link to comment Share on other sites More sharing options...
