The Song Picture

Most audio and video editors employ a representation of music pieces based on the Pulse Code Modulation waveform, from which not much information, besides the energy envelope, can be visually captured. In this work we have discussed the importance of presenting to the user some hints about the melodic content of the audio to improve the visual segmentation of a music piece, thereby speeding up editing tasks. Such a representation, although powerful in the mentioned sense, is of simple computation, a desirable property because loading an audio or video should be done very fast in an interactive environment.
