MP3 Cutter is an audio-editing tool that lets you crop any audio file on your Android’s memory. The resulting file is conveniently saved to the folder ‘sdcard/media/audio/’.
With the MP3 Cutter app, you can take any downloaded MP3 on your phone and cut it shorter to make a customized ringtone or alarm. With this app you can cut from any part of the song and to any length. You can save your cut MP3 to your phone or SD card. You can even cut downloaded songs from YouTube.
Using MP3 Cutter is really simple: just select the audio file, which can be in MP3 or M4A format, and use your fingertip to choose the section you want to crop. You can choose the exact second where it starts and ends. After that, just save the results, and voilà – you have your perfectly cropped audio file.
MP3 Cutter is a great app for two main reasons: it’s really easy to use, and it takes up very little space on your device’s memory.
Cut any MP3 into any length you'd like. And it even works with MP3s from YouTube.
