Abstract

Audio visualization is an important aspect of audio analysis and research. Common audio visualization methods include graphing the amplitude envelope and spectrogram of a given piece of audio. Graphing the amplitude envelope generally gives a good representation of the transience but little to no spectral information, while taking the spectrogram gives a bad representation of transience. In this project we developed code to visualize audio using stacked graphs, an uncommon yet highly intuitive method which gives both a good representation of transience and the spectral information. Methods were also developed for storing audio data such that common time units could be easily used to access and manipulate it.
