the test that tells you if your ear can differentiate between the quality of Spotify and the audio without loss (lossless)

Recently on Spotify they announced that they will finally offer a HiFi model of music in high quality without loss, that is, a true competitor for more niche options like Tidal or Qobuz that appeal to audiophiles.

Meanwhile, Spotify continues to offer the same "high quality" option as always in its streaming, a quality that, to be honest, is sufficient for most of its users, and that even if you feel that it is not enough for you, you may not be able to continue to distinguish from the quality lossless of a CD, and this test is an interesting way to verify it.

Are your equipment and your ears ready for HiFi sound?

Audio Test

The ABX High Fidelity Test offers you a way to test not only your ears but your sound equipment, to see if you can distinguish between Spotify's high-quality streaming equivalent to roughly 320 kbps, and lossless audio quality from a CD that equates to about 1,411 kbps.

The premise here is that the quality of the sound we receive does not only depend on the service that the sound provides us, but obviously on the equipment in which we are going to reproduce it. For example, Bluetooth simply cannot deliver HiRes sound despite great advancements such as the LDAC or aptX-HD codec, the audio is still "lossy". Data is always lost when squeezing the digital audio signal via Bluetooth.

After trying hi-fi music from Tidal, Qobuz and Amazon Music, I have no doubt that I will be using Spotify HiFi

The other point is your ears, not everyone perceives the sound the same, and with age we also begin to hear worse. Most people won't be able to tell the difference in quality most of the time, let alone the difference between CD quality and HiRes, which can go up to 24 bits up to 194 kHz.

Abox Audio Test

Taking this test is an interesting exercise. What it does is offer you some five songs, each in a batch that can range from 5 to 20 repetitions, depending on how much time you want to invest.

It is an "ABX" test because it offers you the same song in three different options: A, B and X. Your goal is to listen to X, and then choose which one sounds more like X, whether A or B. The test does not tell you at any time which song sounds in lossless quality (CD) and which in lossy quality (Spotify), so you go completely blind with nothing to influence your decision.

You can repeat the listening segments as many times as you like, fast-forward or backward five seconds at a time, or start from the beginning. The changes between A, B and X are instantaneous and it is quite difficult to distinguish.

In fact, even with results of around 60 and 80% correct answers, the test will conclude that you probably cannot distinguish between one quality and another, because when the variable that you choose answers at random is included, you could obtain scores that are just as close. .

Although the test works both from your mobile device and from the desktop, they recommend that you do not use it from your mobile if you have limited data, as will transfer between 30 and 40 MB of FLAC files. Files are not cached due to limitations of the FLAC JavaScript audio libraries.
