Audio file splitters are useful when you want to split large audio files into smaller, more manageable pieces. If you want to make ringtones for your phone, for instance, then you can use an audio file splitter app to produce free ringtones from your existing music collection.

Another reason you might want to use an audio file splitter is for large podcasts or other types of digital recording where there is one large continuous audio block. These can be large, and ​splitting them into sections makes them easier to listen to. Audiobooks usually come with chapter divisions, but if you have an audiobook that is just one large file, then a splitter can be used to create separate chapters.​

To start chopping, dicing, and mashing your audio files, check out some of the best free MP3 splitters on the internet.

Wavepad Audio Editor
NCH Software

WavePad Audio File Splitter comes with a good set of features for splitting up audio files. It supports both lossy and lossless audio formats such as MP3, OGG, FLAC, and WAV.

Although the website names this tool as an audio splitter, it's actually more than this; the app's name is a bit confusing, too. However, it's free for home use with no time limits.

What makes this program so versatile is the number of ways it can split audio files. Its most impressive feature is the use of silence detection. This enables you to split a large audio file that contains multiple music tracks.

If you rip an audio CD to one large MP3 file, then this tool is a good option for creating individual tracks. You can then use an ID3 tag editor to add track identifying information—an essential step if you want to know what each song is called.

This software is available for Windows and MacOS computers, iOS devices and Android devices. This excellent free program is flexible and highly recommended.

If you like simplicity, then MP3 Cutter is the tool for you. It has an intuitive interface that's easy to use.

After you load an audio file that you want to split, it's just a matter of setting the start and end positions of the clip. The program also has a built-in player with a play/pause capability. This can be used to play whole tracks or—more likely—a section of audio before you do any MP3 chopping.

Unfortunately, the program supports splitting only the MP3 format, but if MP3s are all you have to work on, then this lightweight application is a great tool to use.

Mp3splt is a great tool for precision audio dicing. It automatically detects split points and silent gaps, which is convenient for splitting up an album. File names and music tag information can be retrieved from an online database—the CDDB—automatically.

You can download this multiplatform tool for Windows, MacOS, and Linux, and it supports MP3, Ogg Vorbis, and FLAC file formats.

The user interface is relatively easy to use, but there is a learning curve. The software has a built-in audio player so you can play whole audio tracks or preview your MP3 slices. If you have a large recording, Mp3splt produces good results.
