Title: Divide large FLAC file into several - without CUE file
Post by: AudiOh on 2018-03-10 11:44:27
Hi everybody. Great to be here. I am hoping someone can help me here (sorry if this is the wrong section).

I have recently bought a digital FLAC file. It is an entire music album and I want to divide it into several files (by the songs). The thing is, the download did not come with a CUE file which is generally used to divide.

When I try to use programs like CUETools or Medieval CUE Splitter it just doesn't work without a CUE file. I don't want to do it manually (with programs like Audacity or whatever).

Looking for your help. Thanks and best regards.

Use foobar2000, convert to flac, but choose to convert each track to an individual file.
This is given that foobar2000 is able to read the file as several songs.

It is necessary to create a CUE program RG CUE MAKER

You can make a cue sheet with Windows Notepad.  Use an existing existing cue sheet (http://wiki.hydrogenaud.io/index.php?title=Cue_sheet) as an example/template.

Or you can use any audio editor.   (Audacity (http://www.audacityteam.org/) is FREE.)     Since FLAC is lossless, there's no problem opening it for editing and then re-saving* bits of it as new FLAC files.




* With Audacity you "export" when you want to save-as an audio file and you "save" if you want to save the Audacity project (for further editing, etc.).

Just slice'n'dice with Audacity. As a one-off job, it's got to be quicker and simpler than creating cue sheets.

You might try generating the cue sheet using

Cool feature of Audacity: you create the split points in a separate "track" and when ready select "Export multiple".

I know three nice Windows programs for this application.

You can use CDwave (http://www.milosoftware.com/en/index.php?body=download.php) to create a cue sheet or directly write split audio file segments. The program can work in any sampling rate, not just CD. The splits are on 1/75 second boundaries. An oddity with the interface is that the spacebar pauses, press F10 to stop, to further tweak the cursor point.

In Sound Forge you can drop Markers at intended split points (including start of the album and end), then Special > Regions List > Markers to Regions, and Process > Extract Regions. No way to quantize the split times to frames as far as I know.

REAPER digital audio workstation. Easy to use, but you can also unintentionally affect the quality with wrong options. Set the project to match the sampling rate of the source, optionally video frame rate to 75 and View > Ruler time unit to frames. Then insert a Region from time selection (shift-R) for every track. Regions at the top of the view are easy to adjust by dragging later. When done File > Render, Master mix, Project regions. Choose the same sampling rate, uncheck dither.

I use http://cuegenerator.net/ which I've found to be the best.

Then once the cue sheet has been created and loaded into foobar for a final check and tweak of the timings, I'll open the cue sheet in Notepad++ (http://notepad-plus-plus.org/) and tweak away, making sure to save and then recheck in foobar, which picks up the saved cue sheet changes.

Didn't know that. I may give it a try next time I have to edit an Elpee's worth of Tunes ((c)Todd Rundgren).

If you are going to use Audacity to split file, it is needed to disable dither in preferences.

Hi,

As this subject is already here I'm digging up this old thread.

Going back to OP, has anything changed since March 2018?

Can Foobar do an in-house creation of track breaks for an album digitised to FLAC as a single file without a cue file AND sort out track numbers and track names?

The post by o-l-a-v did not work for splitting the tracks, I ended up with exactly the same file.

If not, then I guess it's Audacity to the rescue. Fortunately I only have a few Flac files like this.

As there is no cue file, Foobar has no clue where to split.

What o-l-a-v might have been thinking of is the special case where the CUE information is embedded within the FLAC image.  Yes, FLAC album images can contain CUE information, and foobar2000 can read it.  You'd know as soon as you loaded the file into foobar2000 as it would appear in the playlist as tracks.

When splitting with Audacity, note the point above about disabling dither.  Doubtful it's audible, but it's also not necessary unless you are converting a 24-bit image to 16-bit files.  It's one of these two settings and, since I can't ever remember which one, I just set both to "None":

First, know how to make a .cue.  That's a lot easier than building a time machine.

Given you know that -- and I do -- here is what I would do.

Assuming I had only a flac, as in, from a single .wav perhaps ripped from a long-ago destroyed LP never to be seen on CD, I'd export that flac to a single wav file.  Nothing else could be done.  From there...

... I'd play it, locating and noting the track starts.  It doesn't have to be perfect; it's an LP!

I'd start up a text editor and make the .cue.  Or I'd look into making that time machine after all.

Once I had the .cue, I'd drop it on the Import from CD dialog at the lower right of the first image below.  And from there push a button to make a FLAC CD.

From the FLAC CD, I'd load it and from there transcode it using export -- either Export checked tracks, as partly seen in the second image, or use the one-track export from the track list -- to single FLAC files, one per .cue track.

All done.  No time machine needed.
