Why do I need a dolby digital decoder on my TV?

The Dolby Digital processor is a continuation of the Dolby multi-channel audio coding system that was previously implemented. In the absence of a noise reduction signal, Dolby works on the principle of noise reduction, and if it is present, it enables a powerful, high-performance audio signal to interrupt lower-level noise. That is why this technology applies a psychoacoustic model of hearing.

Attention! In the event that the signal fills a separate part of the spectrum, Dolby noise reduction reduces the noise level in certain parts of the spectrum in which there is no productive signal, making it insignificant. This is because the sound signal only hides the nearest frequency noise.

The Dolby Digital prefix covers many other reserves:

increases device resources, guarantees high-fidelity sound transmission in 5.1 format;
creates the correct 5.1 stereoscopic sound using various stereo headphones;
increases the sound distance when using speakers for musical sound reproduction;
produces spatial perception using stereo headphones.
amplifies low sound frequencies;
enhances high frequencies and improves the sound quality of music by correcting the effects of high-frequency pulses;
adds significance to mono sound reproduction;
controls the sound level by maintaining a stable volume level.
