Edit Audio Files on Your Phone: WavePad Audio File Splitter

WavePad Audio File Splitter
What We Like
  • Works with multiple formats.

  • Mobile option.

What We Don't Like
  • Has a learning curve.

WavePad Audio File Splitter supports both lossy and lossless audio formats such as MP3, OGG, FLAC, and WAV. This software is available for Windows, macOS, iOS, and Android devices. 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 feature 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, which is an essential step if you want to know what each song is called.

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's 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.

What We Don't Like
  • Command line only.

FFmpeg might be the most unconventional entry on this list, but it's here because it's super effective. FFmpeg is an open-source command line tool that handles all sorts of multimedia files, including MP3s. It serves as the back end for other applications, but it's fairly simple to use by itself.

With FFmpeg, you can use a simple command to cut out sections of a larger audio file. Specify the time you'd like to start your cut, the time you want it to stop, and the output file, and you're good to go.

Because FFmpeg is a command-line tool, you can get extremely precise with the places you want to break things up. It's also flexible enough to convert your files to a different format while cutting them, so you can take a huge WAV or FLAC and cut it down into more manageable MP3s.

FFmpeg is available to download for Windows or macOS, and Linux users can find it in their distribution repositories.

This one works on any platform, even mobile, and it's great for one-off situations where installing a new program would be excessive.

What Are Audio File Splitters Used For?

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 files 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.
