The best way to get rid of unwanted noise from your music and get the best part of the audio as your ringtone, alarm, or music file is to use this audio editor. This app can edit MP3, WAV, AAC, AMR, and other audio formats.

It's very easy to use and it has a simple user interface. You don't need to know any coding language to use this app. You just need to select the music file you want to edit and then you can cut the best part from it. The cut results are saved in a folder called "/mnt/sdcard/media/audio".
