Since ancient Greece, music from has occupied an important space in the integral formation of the human being [1]. Similarly, music as a cultural expression plays a very important role in the process of building the social environment and has been directly related to the epochs, economic conditions, technical developments and historical moments of the world [2]. Today, great technological advances in the development of mobile devices and the increase of the bandwidth of the telephone and internet services have facilitated not only the growth in the consumption of music, but also the strengthening of its piracy; these factors forced the music industry to make major changes since the late 1990s [3]. Based on this need for innovation, this article describes the development of an application for Android devices that allows music lovers to manipulate the stemps (groups of pre-recorded audio signals) of some predefined songs, which provides them an experience different from that offered by any of the existing music playback platforms and applications for mobile devices. This application seeks to take into account the variable of the perceptual subjectivity of each user, which is assumed by the mixing and mastering engineers to perform a postproduction of audio based on contours of equal sonority, in addition to the consolidation of taste aesthetic, in an audio file that the user can export [4].
