Question 26 • Introduction to Information Technology - EL3701

The goal of an audio codec is

Answer

to make an audio file that sounds good and is as small as possible for use with certain applications.

to make an audio file with the highest amplitude while making sure the decibels are not degraded.

to preserve the original sound quality regardless of conversions that affect sampling rate.

to upload audio files from your computer to your mobile devices.

Explanation

An audio codec encodes and decodes digital audio, often compressing it to reduce file size while keeping sound quality acceptable for its intended use. The goal is not to maximize amplitude, prevent every quality change, or transfer files between devices; those describe other audio or file-management concerns. Choice A correctly describes balancing good sound with a small, application-suitable file.
