For years, Medieval CUE Splitter was my app of choice of splitting gigantic MP3s with their matching CUE files. Unfortunately, the installer fails for some reason on Windows 8.1 x64, and I haven’t been able to find a fix. The good news is there’s a alternative in the form of mp3split, which has much better output, albeit at the expense of a less polished UI. Unlike CUE Splitter, mp3split retains the original encoder data, whereas CUE Splitter’s output somehow always wound up with Xing as the encoder. That last part is curious since CUE Splitter claims it splits without re-encoding, but hey.
Here’s how to split an MP3 with a CUE file using mp3split:
Download the Mp3splt-gtk Windows installer from here. Note that the non-gtk Mp3splt download is the command line tool only, so if you choose that you won’t get a GUI and following steps won’t apply.
Under the Split tab, select the Directory for split files.
Under Split Options, check Frame mode (useful for mp3 VBR) (mp3 only) if you’re splitting a VBR MP3.
Click the Tags tab.
Under Tags version (mp3 only), select Same tags version as the input file.
Ensure both the CUE file and the MP3 you want to split are in the same folder.
Click Import splitpoints from file…
Navigate to the folder in Step 4 and select the desired CUE file.
In the Manual single file split tab, click Split.
You should get a nicely split set of output files in the folder you selected in Step 6 above.
