Syntrillium Backup Forums :: View topic - saving cue's with mp3-file for later use?

Hi
I am helping a friend (using ce 2 pro) to split some mp3 files ( casette tapes) into shorter relevant chunks.
I put a number of track-cues (shift-f Cool

, saved the file as it was, and thought that when I returned I could continue.

oh oh not a sign of all the work I had put in, when i reopened the file later.

have looked into knowledge base and forums but not found anything for me.

I dont want to split the file into fragments from the start. only when i am ready to burn a cd.

is this simple thing possible? to save the various cue markers together with just the original file?

kind regards

Hello Grey. This was actually discussed in a recent thread, and as you've discovered, you cannot retain the Cues in an MP3.

Now, you can retain the Cues in a CEL file...

But, the larger issue is that you're opening an MP3, creating/making changes and then saving back to MP3. This is not the way to go about it, especially if you plan on burning to CD. The main reason is that every time you save back to MP3 you are 're-compressing' and thus throwing away a little more fidelity, degrading the track even further.

If you save to 'Windows PCM wav', this will not occur. If you plan on doing any processing to the file, you should convert to 32-bit first.

Hi
Great, this makes good sense, had not thought on the mp3 degradation angle, but focussed on filesizez. afterall the wav file is around 10 times as large ;-)

you suggest converting to 32 bit. does that apply even if I "just" want to remove noise, like tape hiss..... We have no plans to add or mix other sources.

kind regards

Building on what Synt said, there are a couple of points...

The normal process for doing what you want is to record in 32-bit, because that makes the noise removal process rather more accurate at low levels. Save the WAV file you've made, and put the cue points into this, making sure that when you save the file, you have a check in the 'save extra non-audio information' box. Highlight all the cue points with the mouse, and click on 'merge', which will turn them into cue ranges. Now, you can break these ranges into separate chunks using the 'batch' process, saving them as MP3s - you can set the options from within the batch process setup box.

If you don't want to save everything you've recorded, then highlighting any pair of cue points and clicking 'merge' will merge just these two points into an individual range. Also, if you put information in the cue label (this only applies to CEP2.0), then you can automatically use this as the name for the MP3 file that you create.
