{Disarmed} This is how the Hi-Res audio of the POCO X4 Pro improves the sound quality

This is how the Hi-Res audio of the POCO X4 Pro improves the sound quality

During the official presentation of the new POCO X4 Pro 5G there was something that really caught our attention: the Hi-Res Audio logo. What does it mean? In this article we will delve into this certification and what it does for our ears . There is life beyond the MP3, you can be sure.

What is Hi-Res Audio

To understand how Hi-Res audio works, you must first understand how sound is recorded. The formula is simple: it is a translation from analog to digital and then from digital to analog .

In this process, the analog audio waves are converted into a jumble of data, sound bits encoded and converted into a signal. Later, that file will be decoded and converted back into analog waves that will enter our ears and be interpreted by our brain.

And of course, in these two transformations there are many variables to take into account, mainly the fidelity of the audio, the sampling rate and the intensity of the compression. MP3s and the 44.1kHz standard is limited and old : after more than two decades of being used as the basis for recordings, there are dozens of better alternatives.

As we already explained in our article about Snadragon Sound and Qualcomm aptX Lossless technology , there is no single formula to achieve the best possible result. An intelligent "lossless" compression algorithm capable of reproducing frequencies equal to or greater than 44.1 KHz —that is, audio encoded at a depth of 16 bits and at a sampling rate of 44,100 samples per second—will return a CD-like quality.

However, this quality can be improved exponentially. Hi-Res audio, commonly called "DVD quality", refers to a standard quality of 24 bits deep and 96,000 samples per second.

And for the new POCO X4 Pro to boast this certificate , the mobile's DAC (converter) must be capable of reproducing audio without loss of quality at this resolution . Of course, the quality of the music played and the headphones you listen with also come into play here.

That the new POCO X4 Pro 5G has this certification means that its processor is capable of "translating" music without loss of quality and that it offers the opportunity to listen to it that way, as long as the original source (the music) and the headphones that connect to the 3.5mm jack port on the size.

And what does that mean? That if you listen to compressed music from Spotify, whose highest quality is based on the AAC 256 kbit/s algorithm, you won't be able to get the most out of it. Instead, everything you hear in Hi-Res format, that is, up to 9216kbps (24 bit/192kHz), will sound especially deep and clear, just like the original masters sound before they are digitally compressed. And it's worth it, we assure you.
