We'll often find an MP3 file we like but only a small portion to use for a specific purpose, such as a phone polyphonic ringtone . We can save time and avoid searching for programs that offer a large number of functions by downloading M3 Knife.
The program opens a MP3 file, lets us play it, and when we are done with the piece crop we can press "Select Start". When the segment is complete we need to "Select End". After this, you can save the file to wherever you want with any name and get a perfectly-generated music clip.
MP3 knife will allow us to easily create a polyphonic phone ringtone. This interface is simple and allows us to quickly access the relevant information.
