Check out an MP3 merging client for Mac devices. Work with the options for precisely combining multiple selected tracks into a single composition without losing quality or chopping out fragments of the clips. Avoid re-encoding to get the original sound.
File Stitcher is a utility that provides users an easy way to merge MP3 files together.
Simply drag and drop files into the File Stitcher window and click the "stitch" button to start the process. After MP3s are merged, the user also has the option of editing the ID3 tags for the new file.
