Question

A raw 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

Answer 1

Answer:

Lossy compression is the correct answer of the following question.

Explanation:

Lossy compression is the category of database encryption techniques using unreliable estimations and significant rejecting of data to reflect the information. All methods have been used to expand the size of the information for memory storage, processing, and dissemination.

• Lossy compression is a type of encryption of the software in which sections of the information are missing.

• Lossy compression is the resulting technique of a smaller audio file, which sounds almost the same to the human ear.
