This paper reviews the current state of the Web Audio API, providing some critical considerations with regard to its structure and development. Fol- lowing an introduction to the system, we consider it from three perspectives: the API design; its implementation; and the overall project directions. While there are some very good aspects to the API design, in particular its concise and straightforward nature, we point out some issues in terms of usage, Javascript integration, scheduling and extensibility. We examine the differences in browser implementation of builtin nodes via a case study involving oscillators. Some general considerations are made with regards the project direction, and in con- clusion we offer a summary of suggestions for consideration and further discus- sion.
