In physics, a closely related quantity called  optical depth  is used instead of absorbance: the natural logarithm of the ratio of incident to transmitted radiant power through a material. The optical depth equals the absorbance times ln(10).The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).he optical depth equals the absorbance times ln(10). The term absorption refers to the physical process of absorbing light, while absorbance does not always measure absorption: it measures attenuation (of transmitted radiant power).
What is Automation? Automation is one of the most useful features of REAPER. It enables you to ensure that when your project is played back, changes in such things as volume level or panning for different tracks can be remembered and played back in real time, with the project.
The term Robotic automation refers to the automation of industrial and clerical processes using robots, of various guises. Robotic automation software refers to a class of software products used in that latter, clerical, context. Examples of robotic automation include the use of industrial robots in manufacturing and the use of software robots in automating clerical processes in services industries.
