What is Hi-Fi? Sharing principles and knowledge
01
The definition of Hi-Fi and how to judge whether it is Hi-Fi
Hi-Fi is the abbreviation of High-Fidelity, translated as "high fidelity"
Its definition is: a reproduced sound that is highly similar to the original sound.
Judging whether a Hi-Fi audio system or equipment meets the high-fidelity requirements, through the combination of human ear listening and instrument index testing, the instrument test index is the main basis. Because the test indicators of the equipment can get more accurate quantitative results for reference and comparison, it is more scientific than the human ear test.

How Hi-Fi Works
In the early digital music period, due to the problem of network speed, digital music needs to be compressed, so that there is a lossy MP3 format music. Affected by the file size, the music will be partially reduced and compressed, which will naturally affect the sound quality. .
Hi-Fi is the process of converting digital signals into analog signals, amplifying the analog waveform signals and then playing them back through headphones or speakers.
The purpose is to make the last played sound show the most realistic sound, and feel the various emotions brought by the music.

Common technical terms for Hi-Fi
Thrust: Reasoning represents the minimum capability of a player, whether the output driving power is high or low, often the thrust represents whether it can drive the sound unit better, and whether it can make the unit diaphragm produce effective vibration.
Resolution: Analysis is to ensure the authenticity of the sound, which is the ability to express the details of the sound.
Sound field: the range that the sound from the left and right units can form, which makes people feel immersive.
Real Hi-Fi level audio
High fidelity, strong resolution, large sound field, sufficient thrust
