A few days ago we talked about Apple Sing. Christmas is approaching and Apple wants to help us when it comes to entertain family and friends gatherings allowing us to have a kind of karaoke at home. A karaoke with the mobile, the tablet or the Apple TV.

Apple Sing is not a new app. It’s a new feature coming with iOS 16.2, tvOS 16.2, and iPadOS 16.2 that lets you turn Apple Music into a karaoke. With it, what the application does is remove the voice from the song and leave only the music so that you can be the vocalist. So I decided to try how it works on an Apple TV 4K and after a while… it started to rain to sing to you.

A karaoke at home to use in company

Before continuing, two warnings. The first is that Apple Music Sing is available to Apple Music subscribers around the world. And the second is that only available on all supported iPhone and iPad modelsplus the new Apple TV 4K.

As for iPhone and iPad, it can only be used with the iPhone 11 and later models With the tablet, from iPad 9/10, iPad mini 6, iPad Air 4/5, iPad Pro M1 and M2. And on Apple TV, only the 2022 4K model will work so that last year’s is left out… bad business that Apple.

9 pages and applications to organize a karaoke

With the bases clarified, we must enter into the matter. Apple Sing or Apple Music karaoke mode, what it does is reduce the volume of the lead vocal track in a song. You will stop hearing the vocalist while the rest of the music continues playing and you will see how the lyrics are played on the screen in real time. From there you will be in charge of giving voice to the song.

Apple Sing

All that being said, Apple Sing isn’t available on all songs, though already widely supported at launch and in fact, almost all the songs that I have tried, allow to use this function.

To use Apple Sing, you must start listening to a compatible song and activate the synchronized lyrics mode by clicking on the button shaped like a text balloon with a few quotes. When you do, the screen will show the lyrics of the song and an Apple Sing button with a star microphone icon. In the case of Apple TV 4K, increasing or decreasing the voice is carried out with the volume up and volume down buttons on the remote control.

My personal experience

At this point, I have to tell you how my personal experience has been using Apple Sing with Apple TV 4K. Leaving aside my singing skills, which are pretty much nil, the system works only relatively well.

Almost all songs I’ve tried are compatible with this new function, although when activating it I have encountered a certain lag that sometimes causes me to press the button to access the microphone and go up and down the track or when it comes to lowering the volume, this action will take time in reproducing.


In the video on these lines, you can see how with the Prince song “Cream”, there is a certain delay when turning down the volume and also, when returning to the top, you have to press several times because it does not reach the normal level if you do not insist.

The same happens with the first video that appears in this article, the song “Lodo” by Xoel López. There is a delay in the actions and the volume does not reach the stops, neither below nor above.

Also, it will be a matter of personal perception, but I got the impression that the moment the voice disappears, the moments in which it should appear in the song, the audio track is heard a little lower.

With the voice of the artist already removed, only we will be in charge of acting as vocalists and it is at that moment when we can realize our skills (or lack of them) to dedicate ourselves to the world of song.

Another song with support for Apple Sing

It seems to me a curious function or at least striking, especially in the face of the time that is coming with gatherings of friends and family. However, and having said this, I think that still has work ahead to polish its operation since I have found a usability with too many setbacks.

Also, we must not forget that if we want to use an Apple TV and a television screen that facilitates the reading of the letter, we are going to have to scratch our pockets and buy the latest model which is the only one compatible.

LG’s technology that mixed plasma and LED

Avatar of Thomas Grimm

From 1997 to a good part of the first decade of the 2000s, plasma televisions conquered the high end for a long time. It was the most coveted technology when the user wanted to opt for a panel with the best image quality during that time. However, as we already mentioned in our article about these televisions, the LCD was little by little eating the toastsince its technology was evolving by leaps and bounds.

One of the most noticeable advantages of the LCD was also its lower electrical consumption, thus generating less heat and increasing its useful life. LG wanted to continue betting heavily on plasma televisions, although the manufacturer had to solve the problem of consumption and other aspects if they did not want to abandon the technology. This is how PLED panels were born in 2012.

PLED, an exclusive LG plasma vitamin

PLED comes from the acronym in English Pixel Light Emitting Display. According to the company, this technology brought the best of plasma and the best of LED televisionscombining both Technologys to try to offer a higher image quality, also drastically reducing power consumption at LCD panel values ​​at the time.

When used, a PLED panel is like a vitaminized plasma panel. That is why it is good to remember how plasma panels work to explain their differences. And it is that the screen of a plasma television is formed by two layers of glass between which there are small cells with Xenon and Neon gas which, when excited by an electrical impulse, become plasma, causing the internal phosphor coating of the cell to glow.

What the PLED panel does compared to the plasma is reduce those cells, making each subpixel in a separate cell. This causes the gases to be at a much higher concentration. The cells also contain a denser layer of phosphor.

2023 is going to be a spectacular year in televisions: this is what the main manufacturers are preparing

This concentration means that much less electrical energy is needed to generate the plasma inside each cell. In this way the first advantages of PLED: Its electrical consumption is less than that of conventional plasma and is quite close to what LCD televisions consume.

By consuming less, it also generates less heat and its wear is less. Put at maximum power, a plasma television lasts around 50,000 hours before it starts to degrade. This figure is usually prorated with respect to what would be normal domestic consumption. The resulting figure is about 100,000 hours, which is the figure we all know.


In the case of pledthe highest concentration of Xenon and phosphor increases its useful life up to 80,000 hours of extreme use (as in an airport panel, for example) or 160,000 in a home.


Another of the advantages that PLED continues to maintain from plasma televisions are its self-emissive LEDs. In this way, each pixel can be turned on and off without being subjected to backlighting from a panel of LEDs on the back of the TV. This technology is similar to OLED, although they are not organic LED diodes.

This advantage makes PLED and plasma have better contrast than an LED panel. However, PLED also has an advantage over plasma: its screen is completely matte, reducing the reflection that can be generated by any point of light in the environment. And it is that by the very nature of plasma panels, its glass must always be bright. Sometimes this glare was reduced with anti-reflective coatings, but this diminished the glare emanating from the panel.

PLED also shares the advantages of LED panels

Although we are clear that PLED is like a kind of ‘super plasma’, this technology also includes characteristics of LED televisions, such as electronic image processing, this being the same as that of an LED panel. This eliminates the ‘motion blur’ sensation of plasma TVs in high-speed images, since like LED technology, PLEDs also have three image processors that interleave frames.


Despite the reduction in consumption, PLED screens continued to consume slightly more than LCD panels. In addition, they share the same problem as plasma screens: the ‘burn’ effect when playing still images for a long time.

The OLED was peeking around the corner

Although it was a great advance over plasma panels, the technology did not fully catch on. In addition, they were presented in a context in which the OLED was taking more and more shape (although they were still very expensive to produce) and LCD-LED panels were much cheaper to produce. In addition, with these Technologys the use of elements such as phosphorus and gases was completely eliminated, depending more and more on electronic and digital processing.

In fact, if you asked LG at the time what panels were going to be the future, the company was quick to respond with OLED. And indeed, today it is the technology in which LG has bet the most in recent years.

A couple of years ago Movistar decided to include in its Movistar Plus+ on-demand television platform a series of applications called Living Apps, which allow enjoy different services and content.

so you can configure this useful help

Although our star use is to set timers, music or ask for the time and time, you can ask Alexa for many more things, some as useful as serving as a guardian in your day-to-day life: perhaps if you have left a tap running, if it the washing machine or dishwasher has finished. If you did not know or are not very sure how to make Alexa act on beeps or water, keep reading.

A little over a year ago, Amazon added a series of most useful improvements and functionalities for the home: the audible and in-person detection capabilities. Specifically, we refer to this pair of algorithms:

  • Water Running or running water detection. Thus, by listening to the environment, it is able to find out if there is water running around the equipment, for example because we have left a tap open or because there is a leak.
  • Appliance Beeping Detection. In this case, it refers to the ability of the assistant to listen to the different beeps produced by your electrical appliances when they finish their functions, thus allowing us to act accordingly.

What happens at that moment? If you have developed the corresponding routine, you will receive a message on your mobile. In the first case, it is also possible to program a notice that warns that we are spending more water than normal brushing our teeth, for example. The second is especially useful with household appliances that do not have to be smart, such as microwaves, ovens, refrigerators. So, if you leave the fridge open, Alexa will tell you goat.

How to configure these functions

To benefit from these functions it is necessary to go to the section of the Alexa routines from the application. There you can configure the routine you want so that Alexa executes automatic actions for daily milestones, for example, that the washing machine program has finished.


In the Amazon Alexa application, tap on Further, which you will find in the lower right corner. There select routines and click on the “+” in the upper right corner to create a new Routine.

Alexa 2

There are four steps. The first is to name it. After in “When” Choose “sound detection“. Within that option you will see both options beyond the beep or the water such as snoring, crying baby, coughing or barking dog that can give you new ideas, for example a lullaby sounds when your little one cries. Then choose which device and in what time range. Finally you will have to add the action you want. So, if you want it to reach your mobile, choose “Notification” (yes, you will have to have the notifications of said application activated). However, in “alexa says” You could also choose what the Amazon voice assistant’s response would be by simply typing it in “Custom”.
