Slice Audio File Splitter
Full user review
"Works like a charm for its intended use"
Very fast lossless splitting of audio tracks into multiple files - you can choose to break the master file into a specified number of files, or into x number of files of certain length. I experienced no issues with stability, performance, quality.
Doesn't do much else
If you're looking to chop an audio file into easier-to-swallow and easier to access chunks, this program slices and dices quite well. However, if you need to listen to an audio file and designate cuts at very specific points in a master track, I recommend using an audio editor such as Audacity.
