Topic: Sector Boundry question

[johnw]

I've been using the program CDWave for years now based on someone telling me that it will divide a wav file at a time that is a multiple of some number so there aren't sector boundry issues and there won't be clicking at the end of the file. I never questioned this. Is that true? The reason I ask is because I've been using SF8 to add gain, resample and dither and I'd like to use it to break up a file into tracks if there aren't issues with sector boundries and I don't have to do math to make sure the time is a multiple of some number.

It's true.

Is there a function to break tracks in SF8?

There are a lot of audio editors out there - all of which might handle tracking differently (or not at all)

I think we have collectively "standardized" the post production process - tracking CD wave keeps us all on the same page.

Yes, it is. For a better explanation of why, see http://www.milosoftware.com/cdwave/faq.html#Technical
As for other programs ability to split on a sector boundary, I don't know so I always split in CDWave.

A little reading or testing will give you the answers you want...

I always do my SF work before CDWave.  That eliminates any issues with SBEs that may occur if there are changes to any tracks. 

But in your case, you could split the tracks with SF8, then run the resulting file thru SHNTOOLs LEN to verify there are no SBEs, or do a FIX with SHNTOOLs to take care of them before FLACing. 

Oh, its a good idea to trim the last few 0.0x seconds off your WAV too so you have a nice clean end.  Avoids a pop right as the disc finishes...

There is a bunch of info about this at the ETREE.FORUMs...

Thanks guys. My process is:
Open in SF and scan for peak and then adjust volume to that peak, trim off the ends and save. Open in cdwav and cut into tracks. Open individual tracks in SF and resample then adjust bit rate and save. I also add fades to the end and beginnings of sets. I was just looking for a way to avoid having to resample each individual track - maybe SF8 has a batch function? I thought about just resampling prior to the cdwav step, but I want the 24 and 16 bit files the same track times.

You should resample in SF first then track in CDwave...

You can make a cue sheet in CD wave and use the same splits in both 16 and 24 bit versions...

To check for SBE's adding this string in Foobar player will show the sbe in red after track lenght:

prefs>display>title formatting>

$ifgreater($mod(%_length_samples%,588),0,$rgb(180,90,90,180,90,90)$num($mod(%_length_samples%,588),3),)

i use the same software, my work flow

open in SF
normalize if necessary and other other minor edits
resample
bit-depth converter to 16bit
Save new file

Open CD WAVE import the new 16/44.1 file
Split all tracks including trimming off 1st and last few seconds of the file (unless there was a track split around the 2GB mark then I do not cut off the end of the track)
Save CUE sheet
save individual tracks

If necessary i will reopen specific/individual WAV files to either:
add fades in/out based on tracking
merge tracks that were split due to 2GB file limitations


I used SF to split tracks long ago and it has a few more steps in it than if you used CDWAVE and more importantly to me it didn't seem to have the CUE sheet option which is crucial for me dealing with 24/16 bit. i never encountered any SBE problems when tracking in SF but thats not to say the program is guaranteed not to produce them
