Sorry, nothing listed in our inventory is for sale. We own and use it for a reason. If we do end up getting rid of something, it is probably because it has cursed us too many times, so you wouldn't want it anyway.
The ability to judge PITCH absolutely, without reference to another pitch or frequency. Also called absolute pitch. Perfect pitch appears to be an innate ability of some individuals, whereas related skills, such as remembered pitch or relative pitch which use other pitches as references, can be learned through musical practice.
The atmosphere exerts pressure on all objects in it. When a vibrating body moves in air, it creates slight disturbances of the AMBIENT atmospheric pressure. The AMPLITUDE of these pressure variations is called the sound pressure variation, whereas the effective pressure variation is 0.707 the maximum value. The oscillating variations in sound pressure (called the WAVEFORM of the sound) PROPAGATE in the form of a SOUND WAVE.
The difference in SOUND PRESSURE LEVEL between the saturation or overload level and the BACKGROUND NOISE level of an acoustic or electroacoustic system, measured in DECIBELs. This RANGE may be expressed as a SIGNAL-TO-NOISE RATIO for maximum output.
The device, successor to the MAGNETIC WIRE recorder, which since the 1940s (when it was called the sound mirror) has been the most commonly used means of storing and reproducing an AUDIO signal.
