Mixing engineer
A mixing engineer (or simply mix engineer) is responsible for combining ("mixing") different sonic elements of an auditory piece into a complete rendition (also known as "final mix" or "mixdown"), whether in music, film, or any other content of auditory nature. The finished piece, recorded or live, must achieve a good balance of properties, such as volume, pan positioning, and other effects, while resolving any arising frequency conflicts from various sound sources.
Semi-conducteur organique
vignette|Molécules de quinacridone (semi-conducteur organique) adsorbées sur une surface de graphite. Un semi-conducteur organique est un composé organique, sous la forme d'un cristal ou d'un polymère, qui montre des propriétés similaires aux semi-conducteurs inorganiques. Ses propriétés sont la conduction par les électrons et les trous, ainsi que la présence d'une bande interdite. Ces matériaux ont donné naissance à l'électronique organique, ou électronique des plastiques.
Lye
A lye is an alkali metal hydroxide traditionally obtained by leaching wood ashes (potassium), or a strong alkali which is highly soluble in water producing caustic basic solutions. "Lye" most commonly refers to sodium hydroxide (NaOH), but historically has been used for potassium hydroxide (KOH). Today, lye is commercially manufactured using a membrane cell chloralkali process. It is supplied in various forms such as flakes, pellets, microbeads, coarse powder or a solution.
Pears (soap)
Pears Glycerin soap is a British brand of soap first produced and sold in 1807 by Andrew Pears, at a factory just off Oxford Street in London. It was the world's first mass-market translucent soap. Under the stewardship of advertising pioneer Thomas J. Barratt, A. & F. Pears initiated a number of innovations in sales and marketing. English actress and socialite Lillie Langtry was recruited to become the poster-girl for Pears in 1882, and in doing so she became the first celebrity to endorse a commercial product.
Carboxylate
In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, (or ). It is an ion with negative charge. Carboxylate salts are salts that have the general formula , where M is a metal and n is 1, 2,.... Carboxylate esters have the general formula (also written as ), where R and R′ are organic groups. Carboxylate ions can be formed by deprotonation of carboxylic acids. Such acids typically have pKa of less than 5, meaning that they can be deprotonated by many bases, such as sodium hydroxide or sodium bicarbonate.
Console numérique
Dans l'audio professionnel, une console de mixage numérique permet de traiter des échantillons numériques audio, contrairement à une console analogique, laquelle traite directement le signal. Les services de recherche de la BBC associés au fabricant de consoles Neve produisent une des premières consoles numérique. Ce prototype donnera naissance à la « Capricorn » commercialisée par Neve. Si pour une console analogique le nombre d'entrées induit le nombre de voies de la console, pour une console numérique, de nouvelles notions apparaissent.
