The evaluation of object-based audio reproduction methods in a real-world context remains a challenge as it is difficult to separate the effects of the reproduction system from the effects of the audio mix rendered for that system. This is often comp... Read More about Perceptual audio evaluation of media device orchestration using the multi-stimulus ideal profile method.

An evolutionary computation approach to intelligent music production informed by experimentally gathered domain knowledge (2016)
Presentation / Conference
Wilson, A., & Fazenda, B. (2016, September). An evolutionary computation approach to intelligent music production informed by experimentally gathered domain knowledge. Presented at 2nd AES Workshop on Intelligent Music Production (WIMP), London, UK

A novel methodology for intelligent music production has been developed using evolutionary computation. Mixes are generated by exploration of a “mix-space”, which consists of a series of inter-channel volume ratios, allowing efficient generation of r...

Relationship between hedonic preference and audio quality in tests of music production quality (2016)
Book Chapter
Wilson, A., & Fazenda, B. (2016). Relationship between hedonic preference and audio quality in tests of music production quality. In 2016 Eighth International Conference on Quality of Multimedia Experience (QoMEX) (1-6). IEEE. https://doi.org/10.1109/QoMEX.2016.7498937

In many subjective listening tests, audio is evaluated on either "quality" or "preference". These terms are often conflated. Little evidence has been gathered which explains the subtle differences between these terms in audio perception --- we may no...
