LiFi Technology

 What is LiFi? LiFi, also known as "Light Fidelity" is a wireless optical networking technology, which uses light emitting diodes (LEDs) to transmit data. In 2011, professor Harald Haas made a LiFi demonstration at the TED (Technology, Entertainment, Design) Global Talk on Visible Light Communication (VLC).VLC involves light as medium to deliver high-speed communication in a manner similar to Wi-Fi and agrees with the IEEE standard IEEE 802.15.7. The IEEE 802.15.7 is a high-speed, bidirectional and completely organized wireless communication technology-based standard similar to Wi-Fi's IEEE 802.11. How does LiFi work? LiFi is a high speed, bidirectional, and completely organized wireless communication of data using light. LiFi comprises of several lightbulbs that structure a wireless organization. At the point when an electrical current is applied to a LED light bulb a stream of light (photons) is emitted from the bulb. LED bulbs are semiconductor gadgets, and that means

Hi-Res music streaming services

 Audio has come a long manner on smartphones. Regular streaming offerings have pleasant streaming that’s perfectly quality for Bluetooth headphones. Modern connectivity like 5G and Wi-Fi 6 guarantees buffering is a rarity. Meanwhile, phone specifications are effective sufficient to deal with nearly any audio codec to be had. So, it’s no marvel that Hi-Res audio is turning into an increasing number of common. After all, those with high priced headphones want the satisfactory revel in, even supposing it fees a touch bit extra.

Of course, not all music sources support  Hi-Res audio. To make it less complicated on you, we’ve collected up a listing of the pleasant Hi-Res tune streaming offerings to be had for Android proper now.


What is Hi-Res audio?

Hi-Res audio is generally considered to be any audio document that has a higher example rate and audio bit profundity than CDs. Albums, for reference, are 16-cycle with a 44.1 kHz test rate. Along these lines, anything higher than that is considered to be high-resolution audio.
There is a monstrous discussion about the benefits of Hi-Res audio and whether or not it makes enough of an improvement to issue. Defenders of Hi-Res audio refer to unrivaled sound quality and more detail in the audio file. Furthermore, engineers in music studios work with higher resolution audio so the files should sound more like what the studio engineer planned.
Theres also HD audio, a term that is technically Hi-Res audio yet just barely. Examples include 24-bit audio with a 44.1 kHz sample rate. Most Hi-Res audio uses something like 16-24 bit depth and 96-192 kHz sampling rates. Hi-Res audio includes a variety of audio file formats, including FLAC, ALAC, WAV, AIFF, DSD, PCM, MQA, and many others.

Amazon Music

Amazon Music Unlimited is an unusually robust offering in the Hi-Res music streaming business. In addition to the fact that it offers some exceptionally high-quality sound, yet it includes the Hi-Res stuff as a component of its base cost. You dont need to pay anything extra in request to utilize it like another streaming administrations.
Amazon offers 75 million tracks available in HD quality audio (at least 16-bit, 44.1 kHz) and roughly seven million more tracks in full Hi-Res (24-bit, 192 kHz). Amazon refers to its Hi-Res audio as Ultra HD in case you decide to Google it yourself. The application is OK and includes all of the base stuff like playlists, digital broadcasts, radio broadcast style playlists, and offline support. Different administrations offer more hearty features, yet you truly cant beat Amazons cost. Its $7.99 per month for Amazon Prime members and $9.99 per month for non-Prime users.

Apple Music

Apple Music has the same benefit as Amazon Music Unlimited. It remembers Hi-Res sound for its base cost with no additional items. Apple Music boasts 75 million tracks, which are all accessible in ALAC, Apples Hi-Res sound configuration. Those two highlights alone make Apple Music a convincing choice. Notwithstanding a lot of highlights and tracks, the actual application is very great. You get the basics alongside extras like time-matched up verses, disconnected help, music stations, and the Apple Music 1 station.

Deezer

Deezers Hi-Fi option is pretty decent, although it maximizes at CD-quality audio. The service boasts 73 million songs and all of them are available in high resolution. Some other Deezer features include a tune identification work, a Shuffle mode that introduces you to new music, collaborative playlists, a sleep timer, podcasts, and some other stuff. All in all, Deezer isnt a remarkable most compelling option in this space. Other services have cheaper Hi-Res music streaming with higher quality. In any case, Deezers sound quality is still far superior to MP3 and the app is actually very pleasant more often than not really it could merit the free trial.

Qobuz

Qobuz is a fairly interesting option. It boasts 70 million songs and all of them are available in CD-quality audio. There are an additional 220,000 albums available in Hi-Res. Additionally, Qobuz gives you the option to purchase music, the same way as you can on iTunes or Amazon. That said, only one out of every odd song available for purchase is also available to stream. The app is good and incorporates things like thousands of public playlists, disconnected support, and fair discovery features. It also has articles, meetings, and stuff like that for music fans. Its a bit more costly than others and its still a lot of a developing streaming assistance.

Plexamp

Plexamp is something a bit different on this list. It's anything but a streaming service like Tidal or Apple Music. Instead, its a server you set up on your computer that lets you stream your music to your phone. So you get access to your library via streaming, without needing to carry all the files around with you. Its a good solution for folks who dont have microSD card slots and also own their own music library.

The only disadvantage to Plexamp is it downscales everything to 16-bit, 44.1 kHz. While that isnt ideal, its CD-quality, and thats not bad using any and all means. Plexamp will likely get support for Hi-Res audio later on, however, so it very well might be worth investigating.

Spotify HiFi

Spotify hasnt technically released its Spotify HiFi service yet, however we as a whole know its coming. It should work inside the typical Spotify application so that is an aid for the individuals who appreciate commonality. Spotify has brilliant revelation choices and the capacity to share playlists is very acceptable. We dont know each of the subtleties of Spotify HiFi at this time. Spotify says its CD-quality audio so that is presumably 16-digit, 44.1 kHz. We additionally dont know the cost or whether or not Spotify is making clients pay extra for it. In any case, it should dispatch toward the finish of 2021 and well update this article when it does.

Tidal Music

Tidal Music is one of the most popular options for Hi-Res music streaming. It actually has three levels of music quality 320 kbps MP3, CD-quality audio (16-bit, 44.1 kHz), and MQA (24-bit, 96 kHz). Tidal boasts a collection of 70 million tracks, available in CD-quality audio. Tidal is a bit tight-lipped on how many are available as MQA, however its in the millions. There are MQA-explicit playlists in case you want to go top level all the time.
Tidal is the most costly option on the list, yet it also allegedly pays musicians more money per stream than most other administrations. Basically, you get what you pay for here and thats what makes Tidal an interesting option.
