A440 (also known as Stuttgart pitch [1]) is the musical pitch corresponding to an audio frequency of 440 Hz, which serves as a tuning standard for the musical note of A above middle C, or A 4 in scientific pitch notation. It is standardized by the International Organization for Standardization as ISO 16.
Drivers in California are allowed up to 12 driving hours and 16 on duty hours. Drivers for theatrical or television motion picture productions are exempt if the driver operates within a 100 air-mile radius of the location where the driver reports to and is released from work. These drivers may take an 8-hour break, and are allowed 15 hours on duty.
Organising drivers' duties in such a fashion enables a crew's duties to be spread over 21 hours. The maximum driving time for a two-man crew taking advantage of this concession is 20 hours before a daily rest is required (although only if both drivers are entitled to drive 10 hours).
For standard A440 pitch equal temperament, the system begins at a frequency of 16.35160 Hz, which is assigned the value C 0. The octave 0 of the scientific pitch notation is traditionally called the sub-contra octave , and the tone marked C 0 in SPN is written as ,,C or C,, or CCC in traditional systems, such as Helmholtz notation .

For example, a subwoofer rated at 100 watts may be able to handle 100 watts of power at 80 hertz, but at 25 hertz it might not be able to handle nearly as much power since such frequencies would, for some drivers in some enclosures, force the driver beyond its mechanical limits much before reaching 100 watts from the amplifier.

Pitch scaling is the opposite: the process of changing the pitch without affecting the speed. Pitch shift is pitch scaling implemented in an effects unit and intended for live performance. Pitch control is a simpler process which affects pitch and speed simultaneously by slowing down or speeding up a recording.

THE TURNING POINT The idea started on New Year’s Day in 1980, when my boyfriend (now my husband), Tim, and I woke up in our flat in London. We’d been working in the U.K. for less than a year and living together only a couple of
