Andre's EAC Offset Calculation
Reply #25 – 2006-11-23 13:44:17
For what it's worth, I used a method similar to the one described on Pio2001's page. I did it on 74 CDs, the results are here:2Gether-2Gether 15622 -4507 2Gether-Again 15319 -20753 98_Degrees-98_Degrees_And_Rising 14477 -29145 98_Degrees-Revelation 16172 -7003 98_Degrees-This_Christmas 15337 -108250 Aly_And_AJ-Acoustic_Hearts_Of_Winter 14760 472 Aly_And_AJ-Into_The_Rush -1160 -12 Aly_And_AJ-Into_The_Rush_(Deluxe_Edition) 318 472 Aly_And_AJ-Into_The_Rush_(Japan) 147 -789 Aly_And_AJ-Into_The_Rush_(Rerelease) -1160 -13 A-Teens-Teen_Spirit 15674 -23659 A-Teens-The_ABBA_Generation 16968 -5169 Avril_Lavigne-Let_Go 15360 -13854 Backstreet_Boys-Backstreet_Boys 16551 -12 Backstreet_Boys-Black_And_Blue 23348 -11448 Backstreet_Boys-Millennium 17101 -5585 BBMak-Into_Your_Head 17921 -36561 BBMak-Sooner_Or_Later 43914 -12 BBMak-Sooner_Or_Later_(Japan) 45078 -33264 BBMak-Sooner_Or_Later_(UK) 45250 -93604 Brie_Larson-Finally_Out_Of_PE 14163 -12266 Britney_Spears-Baby_One_More_Time 24254 -12 Cheyenne_Kimball-The_Day_Has_Come -12 -12 Christina_Aguilera-Christina_Aguilera 12724 -32087 Christina_Aguilera-What_A_Girl_Wants_(Single) 15301 -15511 Covent-Nexus_Polaris 17111 -7652 Dream_Theater-Metropolis_Pt_2_Scenes_From_A_Memory 24053 -1878 Dream-He_Loves_U_Not_(Single) 15445 -17251 Dream-It_Was_All_A_Dream 18256 -3148 Dream-This_Is_Me_(Remixes) 16825 -6995 Evanescence-Fallen 11468 -15763 Hilary_Duff-Santa_Claus_Lane 634 -12 Hoku-Hoku 15367 -4506 In_Flames-Come_Clarity 658 -12 JC_Chasez-Schizophrenic 15466 -3667 Jesse_McCartney-Beautiful_Soul -1160 -12 Jessica_Simpson-Sweet_Kisses 14755 -5378 Jump5-All_The_Time_In_The_World 636 -87648 Ks_Choice-The_Great_Subconscious_Club 19119 -5920 Lacuna_Coil-Comalies 45977 -118426 Lacuna_Coil-In_A_Reverie 45449 -120340 Lacuna_Coil-Unleashed_Memories 45502 -6635 LFO-Life_Is_Good 2 -12 Liberty_X-Thinking_It_Over 49261 -84313 Lindsay_Pagano-Love_And_Faith_And_Inspiration 15691 -6411 M2M-Shades_Of_Purple -12 -4804 Mandy_Moore-Candy_(Single) 17957 -3705 Mandy_Moore-Mandy_Moore 39136 -9195 Mandy_Moore-So_Real 722 -16303 McFly-Room_On_The_3rd_Floor -1160 -86372 McFly-Wonderland -12 -12 Mudvayne-The_End_Of_All_Things_To_Come 14537 -7110 No_Doubt-Tragic_Kingdom 14725 -3224 NSync-Home_For_Christmas 17234 -23933 NSync-No_Strings_Attached 7972 -4574 NSync-NSync 16831 -519 Opeth-Blackwater_Park 14799 -5383 O-Town-O2 698 -11294 Play-Dont_Stop_The_Music 15340 -5052 Play-Girls_Mind 16525 -13544 Play-Play 14018 -22647 Play-Play_Around_The_Christmas_Tree 636 -12 Play-Replay 37409 -44907 Play-Us_Against_The_World 16623 -16246 Sarah_McLachlan-Surfacing 8876 -2096 Stacie_Orrico-Genuine 15586 -3172 The_Gathering-Mandylion 46148 -7756 The_Kovenant-Animatronic 16903 -2445 Tool-Undertow -1157 -15455 VA-Kaerlekens_Spraak 24164 -29135 VA-Pixel_Perfect 670 -88212 VA-Radio_Disney_Holiday_Jams_2 15400 -3978 Winds-Reflections_Of_The_I -1160 -22 The numbers listed are offsets (with respect to the current EAC reference offset) needed to make the first track start on a non-zero sample, and to make the last track end on a non-zero sample, respectively. The start offsets can go no lower than -1160 for the start tracks, and no higher than +472 for the end tracks (these are the offsets of the drives I used to rip the start and end tracks, they can't overread). Most of the numbers aren't helpful because the beginning/end are padded with silence. There is only one number that sticks out to me which is -12 (3 CDs have that as their start offset, and 11 CDs as their end offset). There are no CDs with a -30 offset, so to me it seems pointless to change the reference offset when it's not going to bring any practical benefit.
