From the archives University of South Carolina: Many of the more than 46 million sound recordings archived throughout the US carry the risk of being destroyed during an attempt to digitize them, because magnetic audiotape can deteriorate over time. A team of researchers is developing a means to readily assess the structural condition of magnetic […]
“Floyd Toole, a leading expert in the field of sound reproduction, explains how to design the best possible listening experience for recording control rooms and home entertainment systems. This comprehensive work covers the whole sound reproduction chain from multi-channel audio configurations and the loudspeaker/room system to acoustics and psychoacoustics and the evaluation process. Part 1 […]
From the archives …… ANDREW EVERARD / GRAMOPHONE: Despite the tendency of many to run down the UK audio industry as being out of touch, there’s much to applaud in its continued success Two things struck me as 2014 started.

The research into acoustic diffusers at the University of Salford has been extensively summarised in a text book co-authored by Professor Trevor Cox: Acoustic Absorbers and Diffusers Diffusers are used in spaces where acoustics is a critical requirement. They can be used to improve speech intelligibility in railway stations, theatres and teleconferencing rooms and are […]
This multi-zone, Bluetooth 4.0 speaker, featuring aptX, is constructed from a mineral-filled polymer holding four drivers, comprising a proprietary gold dome C-CAM tweeter flanked on angled baffles by dual 76mm-CAM metal cone bass drivers and augmented by a rear-firing Auxiliary Bass Radiator (ABR). The C-CAM drivers are powered directly by class-D amplifiers, generating 40W in […]

Any relative movement of the various electrodes not only affect sinter-electrode capacitances but also variations in current and mutualconductance. Such relative movements can be caused by vibration, such as sudden knocks or even ambient sounds. Mullard presented the results of […]
