Yeah… I should post this article long time ago. HTC HD2 has lot of custom Android ROMs. But I don’t like most of the ringtones that come along. So how to create custom ringtones, alarms, and notification sounds for Android? The task is as simple as ABC by using Ringdroid. It is an Android application for editing and creating your own ringtones, alarms, and notification sounds. And supports MP3, AAC/MP4, WAV and 3GPP/AMR file formats.
Just select your favorite MP3 music. Set the length then save it as ringtone, alarm, or notification sound. That’s it. Ringdroid will help you to create alarms, notifications, ringtones folders in SD card\media\audio and put those sounds there automatically. You can do so manually too.
Download Ringdroid v2.3 here or search for ‘Ringdroid’ in Android Market to download.
