Overall I feel the interactive visualization piece I created with Processing worked well in the media space, with testers commenting they liked the visual effect produced by the input of their own voice.
Using an iterative approach to design in this project allowed me to quickly frame and solve problems that arose, from the early stages of examining the space to coding the visualizer in the later parts of the process. Looking at the broader process and approach I took, there is a clear progression through stages from requirements gathering to prototyping and testing, however within each of these stages I took an iterative approach on a smaller scale, from redesigning our posters to study visual media in the space to prototyping my project in processing – each iteration revealed new problems to me that I explored solutions to in the following version, then solved and tested outside of the space using Minim’s audio player function.
While the audio visualizer I designed is relatively simple, exploring Processing and Minim further could lead me to more complex ways to visualize audio, and get different kinds of data from an input – for example, instead of charting amplitude over time, getting frequency values instead could allow me to create a proper spectrogram within Processing. It could also be applied to a wide variety of audio inputs, from microphones to music tracks, or as part of an app allowing a user to create their own musical audio input and then visualizing it.
I have only scratched the surface, but audio visualization has many potential uses such as in nightclubs or electronic music events to enhance the experience between music and lights or screens. Digitally, audio visualization is also used to provide visual effects to music uploaded to video sites such as YouTube while they don’t have music videos. As technology progresses and more innovative forms of digital media and user input develop, this is something that will stay applicable as it is key to the senses of sight and hearing in perceiving a media piece.
