Abstract: A software application for use on a portable communications device, such as a cellphone, personal digital assistant, personal computer, or other device capable of receiving user inputs and providing audio playback, allows users to select a track and add samples and effects to create a personal audio remix. The user may then share their creation with other users and friends via, for example, e-mail, social networking or specialized community sites for users of the application. Effects may be further generated using an internal accelerometer of the device. Samples and effects are stored with respect to the timing of the selected master track.
