LFD AUDIO: Dr. Bews discusses Integrated Mistral 2018 with and without phono stage

Hello Dr. Bews. What can you tell us about this new release? “The internal phonostage of the Mistral is based on a new circuit, which uses a dual op-amp, so is different to the phonostage LE and needs to be specified at manufacture since the back pcb needs to be modified to allow input “1” […]

Professor M.J Hawksford: Low-frequency sound source localization as a function of closed acoustic spaces

Further development of an emerging generalized theory of low-frequency sound localization in closed listening spaces is presented that aims to resolve the ambiguities inherent in previous research. The approach takes a robust set of equations based on source/listener location, reverberation time and room dimensions and tests them against a set of evaluation procedures to explore […]
