MP3 Splitter Joiner Pro splits a large MP3 file (up to 10 GB) into multiple smaller pieces, and joins multiple MP3 files into a single file.

You can split a MP3 file by file size, pieces count, time or custom selections. MP3 Splitter Joiner Pro provides a time slider bar to visually position the points where you want to split. You can also preview every custom piece, and split with fade-in/out effect and forward and backward overlap. The MP3 splitter keeps ID3 tag information including ID3v1 and ID3v2 when splitting MP3. To save your time, MP3 Splitter Joiner Pro also supports Batch split, you can split a batch of MP3 files at a time.
