Audio Splitter is a web tool for dividing long MP3 files into shorter parts at points of silence. According to its public listing, the splitting happens in the browser, so no separate desktop program is described as required.

The site at audio-splitter.org is aimed at users who have lengthy MP3 recordings and want to break them into sections at natural pauses. The public metadata does not list additional features, pricing, or supported platforms.
