interpretting ripped CD text info 2019-12-03 19:14:52 Ripped a bunch of CDs back in 2014 using cdparanoia and some other tools I unfortunately don't recall. At time I made vorbis lossy encoding but I want opus now, for quality with smaller file size for my phone.I archived each CD rip as a single file along with a file called cdinfo.txt that I know was created with some tool at time of rip but I forget.Anyway would like to reprocess those archived rips into lossy, but like an idiot I did not take any notes on my previous process and don't remember.The cdinfo.txt file (among other things) has the following:Code: [Select]Disc mode is listed as: CD-DACD-ROM Track List (1 - 9) #: MSF LSN Type Green? Copy? Channels Premphasis? 1: 00:02:00 000000 audio false no 2 yes 2: 05:22:40 024040 audio false no 2 yes 3: 10:34:20 047420 audio false no 2 yes 4: 15:40:42 070392 audio false no 2 yes 5: 20:24:02 091652 audio false no 2 yes 6: 24:47:50 111425 audio false no 2 yes 7: 28:20:15 127365 audio false no 2 yes 8: 32:00:20 143870 audio false no 2 yes 9: 35:46:55 160855 audio false no 2 yes170: 39:50:60 179160 leadout (401 MB raw, 401 MB formatted)Looking at the MSF value in #2 and the MSF value in #1 and taking the difference I get 5:20 which is the length of the first track.Can I assume that the MSF value then specifies the beginning of the track in the CD? e.g. first track starts 2 seconds in?Can I assume that the AA:BB:CC is Minutes:Seconds:SixtiethOfSeconds ??What is the LSN ??This rip is Tom Petty - Southern Accents.What I am doing with reprocessing is applying the deemph, then EBU R128 loudness normalize (via ffmpeg-normalize) - yes can use tags for that but a lot of players don't respect them. Then resample to 48/16 (ffmpeg-normalize leaves it at 192/16) via sox with dithering. Then split into individual wave files, then lossy encode.But I need to know how to interpret the MSF and maybe LSN to get sox to split correctly.I just didn't take notes on what those things mean, given that nothing in the : delimited fields are > 59 I assume they are scale of 60 but I have no idea what the LSN field is.Thank you to anyone familiar with this format.
