An audio engineer works on the recording, manipulation, mixing, reproduction, and reinforcement of sound. Audio engineers work on the "...technical aspect of recording—the placing of microphones, the turning of pre-amp knobs, the setting of levels. The physical recording of any project is done by an engineer... the nuts and bolts." Many audio engineers creatively use technologies to produce sound for film, radio, television, music, electronic products and computer games. Audio engineers also set up and operate sound reinforcement systems for concert, corporate, theatre, sporting and other events.
Audio engineering concerns the creative and practical aspects of sounds including speech and music, as well as the development of new audio technologies and advancing scientific understanding of audible sound.
electric field (see electrostatics): an especially simple type of electromagnetic field produced by an electric charge even when it is not moving (i.e., there is no electric current). The electric field produces a force on other charges in its vicinity.
A railway electrification system supplies electric power to railwaytrains and trams without an on-board prime mover or local fuel supply. Electrification has many advantages but requires significant capital expenditure. Selection of an electrification system is based on economics of energy supply, maintenance, and capital cost compared to the revenue obtained for freight and passenger traffic. Different systems are used for urban and intercity areas; some electric locomotives can switch to different supply voltages to allow flexibility in operation.
Characteristics of railway electrification
Electric railways use electric locomotives to haul passengers or freight in separate cars or electric multiple units, passenger cars with their own motors. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches and transformers.
In their native United Kingdom, Electric was BBC Radio 2's Album of the Week from 8 July 2013. It features a collaboration with British singer-songwriter/rapper Example.
Electric hit No. 3 and No. 26 in the UK and US respectively, their highest chart performances in both territories in 20 years. The album also performed very well in other markets. It was supported by the Electric Tour which visited 46 countries through 112 concerts.
Background and release
Pet Shop Boys recorded the album in London, Berlin and Los Angeles from November 2012 to April 2013. On 30 April 2013, the duo announced on their website that they had recorded the album over the "last six months", with "Fluorescent" in particular "written and recorded within the last month". Stuart Price was chosen to produce the album. Price finished mixing the album in late April 2013.
