When developing audio applications, different choices on software implementation aspects influence the total audio software signal path and can be of importance from an audio quality perspective. The field is not well documented in the literature. A study was carried out aiming at identifying relevant questions that must be considered. The general development perspective was on audio software written in C++ to be run on general purpose CPUs. A research review, comprising literature from different fields such as audio engineering, computer science and software engineering, was conducted to summarize and integrate an overview of the field. The result can be viewed as a map of questions for future research activities, consisting of further literature studies and experiments with software prototypes.
