Parameter mapping sonification is a powerful tool for data display and analysis with uses in a myriad of fields of study. Despite the wide range of applications, parameter mapping sonification remains abstruse for people to utilize effectively. This article outlines an original design in the domain of parameter mapping sonification applications for a flexible, extensible, and intuitive web app that democratizes this data display method. Sonification Interface for REmapping Nature (SIREN) accomplishes these goals through an accessible interface for sonification that demonstrates various web technologies, including Web Audio API. Existing frameworks are compared in five different areas—technology, design, functionality, accessibility, and extensibility—to determine the optimal gap for SIREN.
