Araw digital sound file samples a sound wave at some interval and measures the height of the wave at each point. thus, raw sound is recorded as a list of numbers. in very broad terms the mp3 audio compression algorithm identifies frequencies and volume levels - low and high - that are outside the range of human hearing and removes the data representing these frequencies from the original. this technique results in a smaller audio file that sounds exactly the same to the human ear. this technique is an example of what type of compression? group of answer choices

Lossy compression

Explanation:

In IT, lossy compression also known as irreversible compression is referred to as class of a data encoding technique that tends to use the inexact approximation and also the partial data discarding in order to represent its content. These methods and techniques are used in order to reduce the data size for handling, storing, and transmitting content.

~kinetic ~potential

explanation:

kinetic and potential energies would be types of mechanical energies.

productive most commonly means: achieving or producing a significant amount or result.

explanation:

productive can also mean:

these depend on how the word productive is used. most likely productive will mean   achieving or producing a significant amount or result.
