mp3splt

Used it on Win11 25H2 and it works fine :-) I used it to split long MP3's into equal time chunks. It worked fine. Take note of where it dumps the output as this is a bit quirky. You can set this under preferences but you might want to do a test run first and see where it lands them. Very pleased.

It's quick and simple. Make sure to go to Preferences and select your output folder so you know where your files are going.

Once you get used to the UI, this works perfectly for auto-splitting, labeling and generating cue files.

Love this. Works perfectly and very easy to use. Used it to split a large audiobook into 154 specific parts (via command line).

I downloaded this software as a means to split a single 11-hour audio book file into sections I could easily pick up from while listening in the car. This software worked wonders. The software was very easy to install. I ran the GUI version and within seconds I was able to automatically split the entire 11-hour MP3 file into manageable sections using the "batch split at intervals" feature. I set it to whatever interval I wanted (I choose every 600 seconds, or 10 minute intervals), and within literally seconds, the whole 11-hour MP3 was split into 69 ten-minute sections. What's better, the file output format is fully customizeable and intuitive. I used "@N @f"and was able to have each file start with a track number and the name of the file, for easy sorting on my MP3 device. Overall, this is an elegant piece of software. It's simple to use but is also packed with very handy features for both the casual user and the power user alike. Highly recommended!
