You’ve certainly experienced one of those cases when there is a really cool song you want to have as a ringtone, but the problem is that the part you like most begins somewhere around 1:36… Well, for these cases, you can now use RingDroid
– an application for Android that allows you to quickly and easily create your own ringtones. The interface is pretty simple - the track appears as a waveform and you have two sliders to mark the start and end points. You can also zoom in or out for a better view. Once you have selected the part you want to have as your new ring tone, you simply need to save it. You can use RingDroid to edit WAV, MP3 and 3GPP/AMR audio files.
