What is line in-line out recording on an audio device?

Answer 1

This is the standard protocol of electrical connectivity between devices from different manufacterers. It means the signals have gone through a preamplifer circuit and are within a specific range of amplitude, voltage. and current so that they can be detected properly without damaging the device on either end of the wire and without being too weak to hear or incredibly loud or "clipped" which sometimes causes poor quality sound.

A simple microphone in many cases would need a separate preamplifier circuit to be used in a line-in jack on a power amplifier unit. A line-out signal would normally drive a stereo headphone or earbuds but would need a power amplifier unit to plug into in order to drive most stereo component speaker boxes at a level that you could hear properly. .

Answer 2

Audio equipment operates using different types of audio signals with different strengths based on the internal components of each device.

Microphones genrate the weakest audio signals which requires the recorder to have some sort of internal amplification device.

Most other audio devices generate a pre-amplified signal which is stronger and is referred to as "line level" which is an industry standard for audio equipment to be able to be intergrated with one and other. This standard requires the equipment to be capable to generating or recieveing this particular type of signal.
