Re: Splitting 16/48 tracks?

As an example of it working properly for me, the six show run of Heart shows I saw 1 year ago (today is anniversary of one of them) were recorded at 24/96. I uploaded 24/96 master clone versions here of all 6, all split on "perfect seconds" in Wavelab. I used these files as the basis of my remastered versions that were EQ'd, then downsampled and dithered to 16/44.1. The finished files had no SBE's or any other errors of note.

I remember that I did some experimentation, mastering from the full wav files as well as from the split wav files. The end result was the same. Maybe the program that you used to split files isn't as accurate as Wavelab? I don't know. I can report, though, that I've never had a SBE from splitting on a second - it takes some extreme zooming in to find the no-fraction zone...

Just about everything I've done for the last couple years is put in the computer as 24/96, and split "to-the-second" and it's always correct. I split and master with Wavelab in 24/96, then use Sox resampler via Foobar to downsample my files, and iZotope RX advanced to dither. The 16/44.1 files that come out the other end have no errors. maybe I'm lucky? No. If it's done right, it works...

Re: Splitting 16/48 tracks?

Ok, it was the software. I'd used Audacity for everything. The "snap-to>seconds" function worked perfectly, the error came from using Audacity to resample. I resampled the same file with command line Sox and the result was perfect. Both results have a basic 44-byte header, but Audacity's output is 4 bytes larger than Sox's output, so Audacity "may" have added one extra sample per channel.

So, it seems that the best method is to split on seconds, or possibly 1/75 seconds (will experiment), and leave it up to anyone downstream wishing to convert to CD to use appropriate software.

Thanks for the schoolin'

....and it also worked properly when using Audacity to split 48 kHz file at 75 fps and then using Sox to resample to 44.1

Re: Splitting 16/48 tracks?

....but does _not_ work when splitting the 48kHz file with wavbreaker and resampling with Sox. I don't have a means to try CDWave.

Re: Splitting 16/48 tracks?

@ Audioarchivist -- Wavelab 6 I know does everything and more that CDWAVE does as long as the settings are setup correctly. I would assume even if you did not cut on the exact second you would still be SBE free assuming your settings are correct. If that's the case you may be wasting time zooming in and all and doing the way you proceed. I know CDWAVE cuts on sector boundary regardless of where you split.

Re: Splitting 16/48 tracks?

I always split my 24/48 or 24/96 files with CD WAVE, never had an SBE when I downsampled to 16/44.1.
