Although the hardware is limited to four separate sound channels, software such as OctaMED uses software mixing to allow eight or more virtual channels, and it was possible for software to mix two hardware channels to achieve a single 14-bit resolution channel by playing with the volumes of the channels in such a way that one of the source channels contributes the most significant bits and the other the least.

Although ion engines had been developed at NASA since the late 1950s, with the exception of the SERT missions in the 1960s, the technology had not been demonstrated in flight.

Although the engine produces just 92 millinewtons ( 0. 331 ounce-force ) thrust at maximum power ( 2, 100W on DS1 ), the craft achieved high speeds because ion engines thrust continuously for long periods.

"</ ref > Although this efficiency limitation can be a drawback, an advantage of heat engines is that most forms of energy can be easily converted to heat by processes like exothermic reactions ( such as combustion ), absorption of light or energetic particles, friction, dissipation and resistance.

Although Hannibal surprised the Romans and thoroughly beat them on the battlefields of Italy, he lost his only siege engines and most of his elephants to the cold temperatures and icy mountain paths.

Although rotary engines were mostly used in aircraft, a few cars and motorcycles were built with rotary engines.

Although these early engines were crude and inefficient, they attracted the attention of the leading scientists of the time.

Although Mazda produced an experimental Wankel that year, NSU was first with a Wankel automobile on sale, the sporty NSU Spider in 1964 ; Mazda countered with a display of two and four rotor Wankel engines at that year's Tokyo Motor Show.

Although many manufacturers licensed the design, including Citroën with their M35 and GS Birotor, using engines produced by Comotor, General Motors, which seems to have concluded that the Wankel engine was slightly more expensive to build than an equivalent reciprocating engine, although claiming having solved the fuel economy issue, but failed in obtaining acceptable exhaust emissions, and Mercedes-Benz which used it for their C111 concept car, only Mazda has produced Wankel engines in large numbers.

Although the rule still applies, the visible fuselage " waisting " can only be seen on a few aircraft, such as the B-1B Lancer, Learjet 60, and the Tupolev Tu-160 ' Blackjack ' — the same effect is now achieved by careful positioning of aircraft components, like the boosters and cargo bay on rockets ; the jet engines in front of ( and not directly below ) the wings of the Airbus A380 ; the jet engines behind ( and not purely at the side of ) the fuselage of a Cessna Citation X ; the shape and location of the canopy on the F-22 Raptor ; and the image of the Airbus A380 above showing obvious area rule shaping at the wing root, which is practically invisible from any other angle.

Although the Kiwi / Phoebus / NERVA designs were the only ones to be tested in any substantial program, a number of other solid-core engines were also studied to some degree.

Although it was widely debated whether there was a difference in quality or performance between the two engines, there was no question that the engines were different from one another.

Although it was the popularity of the Oldsmobile division vehicles that prompted this change, declining sales of V8 engines would have made this change inevitable as all but the Chevrolet version of the 350-cubic-inch engine were eventually dropped.
