Stratosfear is an electronic music album released in 1976 by the German group Tangerine Dream. It marks the beginning of the band's development away from their uncompromising early 1970s synthesizer experiments toward a recognizably more melodic sound, a trend they would pick up again in 1979's Force Majeure. The title track "Stratosfear" has been played live many times and has been released in a re-mixed form on a number of other albums.
Stratosfear combines Tangerine Dream's acoustic and electronic influences more tightly than before. For instance, at the end of the last track, "Invisible Limits", the deep piano/flute tune reveals the album's romantic flavour even after the earlier predominantly synthetic compositions (tracks #1 to last part of track #4).
The LP reached No.39 in the UK, in a 4-week chart run, and eventually reached silver status for selling in excess of 60,000 copies.
Nick Mason of Pink Floyd did the original mix of Stratosfear in April 1976 at Hansa by the Wall. Due to disputes between Tangerine Dream and Virgin, this mix was abandoned.
Supersonic speed is a rate of travel of an object that exceeds the speed of sound (Mach 1). For objects traveling in dry air of a temperature of 20 °C (68 °F) at sea level, this speed is approximately 343.2 m/s, 1,125 ft/s, 768 mph, 667 knots, or 1,235 km/h. Speeds greater than five times the speed of sound (Mach 5) are often referred to as hypersonic. Flights during which only some parts of the air surrounding an object, such as the ends of rotor blades, reach supersonic speeds are called transonic. This occurs typically somewhere between Mach 0.8 and Mach 1.23.
Sounds are traveling vibrations in the form of pressure waves in an elastic medium. In gases, sound travels longitudinally at different speeds, mostly depending on the molecular mass and temperature of the gas, and pressure has little effect. Since air temperature and composition varies significantly with altitude, Mach numbers for aircraft may change despite a constant travel speed. In water at room temperature supersonic speed can be considered as any speed greater than 1,440 m/s (4,724 ft/s). In solids, sound waves can be polarized longitudinally or transversely and have even higher velocities.
Supersonic is a studio album by Korean singer Younha, released on July 03, 2012. While technically her fifth Korean album, it is fourth album as a whole, as referenced by the album title.
