Splitting 16/48 tracks?
This should be an easy one, but damned if I can find the answer anywhere. In the past I've always dealt with 16/44.1 and know all about SBE's, but I'm not sure how to go about splitting 16/48 into tracks. What's the most common method? How do people usually listen to 16/48 files, and does it even matter how they're split? A link to a tutorial would be great.
I don't necessarily need software advice, I prefer to understand how stuff works rather than letting a piece of fancy software do my thinking for me, but if it helps I run Slackware Linux. Thanks!!! No members have liked this post.

Re: Splitting 16/48 tracks?
Audacity can do it (here's a good guide, make sure to read the "Extra notes about burning to CDs" section)
http://wiki.audacityteam.org/wiki/Sp...eparate_tracks Although CD's don't support 48khz, I'm pretty sure you could still use it. I think most people listen to them through their computer so SBE's probably wouldn't make much difference, but I feel like its still a good idea. No members have liked this post.

Maybe I'll just PM someone who's seeded a 16/48 show and ask them, and then post here in case it will help someone else. No members have liked this post.

Re: Splitting 16/48 tracks?
SBEs won't be an issue. They only matter if you're doing 16/44.1. If you aren't doing redbook standard, lots of software will give you an error if you try to do anything regarding SBEs.
Most audio players will handle 16/48. foobar does no problem, all the way to 24/96. Maybe higher, but I haven't done any higher. If you've already spread those shows in 16/44.1, I wouldn't bother to do so in 16/48. The difference is negligible, most likely not noticeable at all. No members have liked this post.

Re: Splitting 16/48 tracks?
16/48 (or 24/48 or 24/96 files) technically can't have SBE's per se - those sample rates are not made for CD's. Having said that, if you take higher res files and downsample and dither them to 16/44.1, if they aren't split at the right places, they will possibly have SBE's at CD rates...
What I do when processing my 24/96 files is to only split tracks to the exact second. That is, no fractions of a second. CD sectors mean that each second is split into 75 frames. If you split a file between the points that these frames are, that makes a SBE. It's hard to tell where those other 74 frame boundaries are, but there's one at each perfect second. So, splitting a file to be exactly down to a perfect second with no fractions of a second will ensure that your hi-res files will never have any future compatibility issues with SBE's when they are converted to CD quality... no fractions = no SBE's make sense?

Re: Splitting 16/48 tracks?
Samplerate has nothing to do with S.B.E.'s except when converting from one samplerate to another. S.B.E.'s are dependent on the register sizes of the processor processing the audio. It has to do with binary numbers if the procesor register size required is 16 bit based on the bit depth then the audio has to be able to be split into a sample size that is an equal amount of 16 bit samples. If it isn't you get an S.B.E., same goes with 8, 24 or 32 bit. Changing samplerates in simplest terms changes the file size or sample size so a split that was correct when done at one samplerate will not be an even split at another even if the bit depth hasn't changed simply because you add or remove samples from the conversion process. If you change bit depths like from 24 to 16 bit you'll have the same problem. Almost no programs I know of take into account 24 bit sample sizes except for cdwave editor. It is the only program I know of that when it does the splits, it uses a sample size that is a multiple of 16 and 24 so you won't get an S.B.E. regardless of the bit depth used. It is useful for large audio files in that even if you make a cue sheet you can reuse it for all bit depths and sample rates supported, you just need to leave a little bit of silence at the end and lob it off for the final track split.

Re: Splitting 16/48 tracks?
my advice for DAT tapes or any digital media:
always do "unedited" digital 1:1 clones on harddisc and save them like that (unedited) multiple times (on data dvdr, harddiscs etc.). this way you're always goin to have the chance in the future to re-do the original recording of you. like DVD-Audio, CDR, whatever. as for myself i prefer to create 16bit/44.1khz FLACs wthout SBEs from any audio recording in any bitrate i'm doing....for verifying the show and listening pleasure on CDR or mobile audio devices. as for DAT 16/48 and downconverting to 16/44.1khz highest quality....my ears fail to hear a difference (and my ears are still good!!).

So, unless someone can give good reason otherwise, it seems that the answer to my original question is that it really doesn't matter where 48kHz files are split. Anyone listening to them at 48 won't care, and anyone downsampling to burn to CDR will have to fix them anyway. Thanks again to all who have replied. No members have liked this post.

Re: Splitting 16/48 tracks?
I just use CD Wave to split tracks regardless of sample rate. All the usual sample rates (except 32kHz) can be divided evenly by 75 so I just split everything at the nearest 1/75 second to where I want.
When working with high resolution audio I usually make a 16bit/44.1kHz copy too, so I make that copy before splitting tracks, open either copy in CD Wave to set the track marks, save a cue sheet, and apply that cue sheet to all versions. It's not much extra work for me. In theory you can probably just make the high resolution copy and later convert each track to 16bit/44.1kHz for CD without any trouble. If the tool you're using does not alter the duration and handles the very beginning and end of the file nicely -- I've never bothered to look into it. No members have liked this post.

If anyone has converted a 48kHz show to 44.1kHz and found it to be SBE-free, I'd appreciate a link to the torrent. No members have liked this post.

Re: Splitting 16/48 tracks?
That probably has something to do with the software you used. I haven't tried it, so I can't tell you what program would handle it perfectly.
In theory, a program that's careful about it should be able to give almost identical results regardless of if you downmix before or after splitting tracks. The only real difference should be that the very last sample wouldn't be interpolated using the data from the next track. I think. No members have liked this post.
