What Is a Optical Cable?

Published

on

The optical audio port is a digital connection that uses fiber optic cables to transmit sound. It is typically used to connect a CD or DVD player to a sound system, but it can also be used to connect other types of audio equipment. The main advantage of the optical audio port is that it can carry a digital signal over long distances without losing quality. In addition, the cables are relatively inexpensive and easy to find.

However, the optical audio port does have some disadvantages. For one, it is not compatible with all types of audio equipment. In addition, the cables are somewhat fragile and can be challenging to install. As a result, the optical audio port is best suited for those who need high-quality digital audio transmission over long distances.

Optical Audio in my Past Personal Life

In the old days, I connected my devices with my AV-Receiver. I used an optical audio cable to the optical audio in-port on my AV-Receiver. To be honest, that is old-fashioned.

Optical Audio in Personal History
Personal History

Today there are so many wireless options available that it just doesn’t make sense to use a wired connection anymore. Wireless connections are more convenient and allow you to move your devices around without worrying about tangled cables.

Additionally, wireless connections tend to be more reliable than wired ones. So if you’re still using an old AV-Receiver, it might be time to upgrade to a newer model that supports wireless connections.

What Exactly Is Optical Audio?

Most of the cabling you use for your media centers, personal computers, and audio/visual equipment uses electrical signals. Be it analog or digital, the signal is sent as an electrical impulse over a conductive wire. Every cable, from the speaker wire on your 1970s turntable to the HDMI cable on your new HDTV, contains wires, wires, and more wires inside.

The one standout in the home audio/video market is the optical audio cable. Unlike other cabling standards, the optical audio system uses fiber optic cables and laser light to transmit digital audio signals between devices. The standard was introduced in 1983 by Toshiba and was initially intended for use with their fledgling Compact Disc players. (you’ll sometimes hear them referred to as Toshiba-Link or TOSLINK cables.

While electrical cables are susceptible to interference from things like power lines and other electronic devices, optical cables are not. This means they can transmit a purer signal with less degradation than their electrical counterparts.

In addition, optical cables are much thinner and more flexible than electrical cables, making them easier to route through tight spaces. However, there are a few downsides to optical cables as well. For one, they’re not as widely available as electrical cables. In addition, they’re more fragile and can be damaged if bent too sharply.

How Does Optical Audio Work?

At its most basic, optical audio is nothing more than a digital signal encoded onto a beam of light. This light is then sent down an optical fiber cable to its destination, where it’s decoded back into a digital signal.

While this might sound complicated, the process is quite simple. Optical audio cables have two main parts: a transmitter and a receiver. The transmitter encodes the digital signal onto a light beam, while the receiver decodes the signal back into a digital format.

In between the transmitter and receiver is an optical fiber cable. This cable is made up of thousands of tiny glass fibers that are bundled together. These fibers are fragile, measuring just a few microns in diameter. (For reference, a human hair is about 100 microns in diameter.)

The transmitting end of the optical audio cable attaches to the source device, while the receiving end attaches to the destination device. The transmitter encodes the digital signal onto a light beam, which is then sent down the optical fiber cable to the receiver. The receiver decodes the signal back into a digital format, which is then sent to the destination device.

What Are the Benefits of Optical Audio?

A few key benefits of optical audio make it appealing for home theater and audio applications. First, optical audio cables are much thinner and more flexible than electrical cables. This makes them easier to route through tight spaces, making them ideal for installations where space is limited.

Second, optical audio cables are not susceptible to interference from other electronic devices or power lines. This means they can transmit a purer signal with less degradation than their electrical counterparts.

Finally, optical audio cables are available in longer lengths than electrical cables. This makes them ideal for installations where distance is a factor.

What Are the Disadvantages of Optical Audio?

There are a few downsides to optical audio as well. First, optical audio cables are not as widely available as electrical cables. This means they can be more expensive and harder to find. Second, optical audio cables are more fragile and can be damaged if bent too sharply. This makes them more challenging to work with than electrical cables.

Third, optical audio cables have limited bandwidth, meaning they can’t carry as much information as electrical cables. This limits their use to applications where audio quality is not a primary concern.

Fourth, optical audio cables are not compatible with all devices. Some older devices, for example, do not have optical audio outputs. This means you may need to use an adapter to connect your device to an optical audio cable.

Finally, optical audio cables require careful handling to avoid damage. They should be stored in a dry, dust-free environment and should not be bent too sharply.

How to Choose an Optical Audio Cable

When choosing an optical audio cable, there are a few things to keep in mind. First, consider the length of the cable you need. Optical audio cables are available in lengths ranging from a few feet to over 100 feet. Second, consider the type of connections you need. Optical audio cables have either Toslink or mini-Toslink connectors.

Toslink connectors are larger and more robust, making them ideal for home theater applications. Mini-Toslink connectors are smaller and less obtrusive, making them ideal for portable devices. Third, consider the quality of the cable you need.

Optical audio cables are available in various grades, from inexpensive consumer-grade cables to high-end professional-grade cables. The cable grade you need will depend on the application you are using it for.

For example, connecting a portable music player to a home theater system will need a high-quality cable to ensure optimal audio quality. On the other hand, if you are connecting a TV to a sound bar, a lower-quality cable will suffice.

Optical cables are ideal for transmitting digital audio signals over long distances. They are also immune to electromagnetic interference (EMI), making them ideal for installations where space is limited or where there is potential for EMI interference. However, optical cables have limited bandwidth and are incompatible with all devices. When choosing an optical audio cable, consider the length, type of connectors, and quality of the cable you need.

How Enable Headphones Windows 10

Published

on

With the release of the Windows 10 October 2018 Update, a new feature was introduced that allows you to quickly toggle your headphones on and off.

This feature is called ‘Headphones Toggle’ and is available in the Windows 10 sound settings menu. You can access these by clicking the volume button on your device or via the device menu.

You can either toggle audio off for all applications or just Spotify, for example. This is great for when you are doing a task that requires concentration and do not want any distractions.

Previously, you had to go through several steps to completely turn off your headphones. You had to go to the Sound panel, then change the default device to ‘No Device’, then restart your computer!

This new feature makes it much easier to disable your headphones on your computer! Are you a frequent headphone user? Try this feature out and see how it helps you.

Type audiosrv

Now that you have opened the Audio window, you can start to disable the headphones feature. To do this, type DisableDevice and then hit Enter. A box will appear asking you to select a device to disable.

Search for Headphones and then select them from the drop-down menu. Then hit Disable and then OK. You have successfully disabled the headphones feature on your computer!

You can close the Audio window at this point, but it is recommended to keep it open in case you need to re-enable the headphone feature or make other changes. Keep in mind that re-enabling the headphone feature is just as simple as disabling it.

Re-enabling the headphones requires only two steps: opening up the Audio window again and hitting Enable Device. Easy as that! Anyone can do it.

Click on Audiosrv

Next, click on the Settings option. You will find this in the Windows 10 navigation bar that includes the back button, home button, and open windows button.

A new window will open with a variety of settings to edit. One of these is the Settings page where you can edit your personal settings and adjust system settings.

In this section, there is an Audio setting tab where you can edit your headphone preferences. By clicking on this tab, you can easily enable headphones on your computer!

Under the Sound section, there is a drop-down menu that says Output Device. This is what controls what device produces sound from your computer. By default it is set to Internal Audio and this does not allow for external devices to produce sound unless you connect them.

Hold down Ctrl + Shift + B

how enable headphones windows 10

Now, this shortcut requires you to hold down the Control, Shift, and Backspace keys at the same time.

It might seem weird at first, but this combination disables your device’s ability to detect device attachments. This includes headphones!

So, if you want to listen to music or a video with your headphones attached but do not want to hear the audio from the screen, then this is the shortcut for you!

It takes some getting used to, but after doing so once or twice you will see the benefit. You can then disconnect your headphones and continue using your computer as normal.

If you want to re-enable your device’s ability to detect device attachments, then all you have to do is hold down the Control, Shift, and Backspace keys again and dis-connect your headphones.

Click on Restart

how enable headphones windows 10

Once in the restart menu, you will need to select some settings. First, you will need to make sure that you have your computer save your open files and close down properly.

Next, you will need to have it reboot into the default boot device. Finally, you will need to have it log you out so that it can properly restart your computer.

These are very important settings so that your computer can properly restart. Make sure to check all of these settings and that they are correct!

If you are having trouble with your headphones and audio on Windows 10, try checking if the Disable all audio components setting is enabled. If it is, try disabling it and re-plugging in your headphones to see if that fixes the problem.

This problem could be caused by a number of things, from broken wires in the headphones to a faulty device driver on your computer. Try checking out the Device Manager on your computer and see if any devices have an error symbol next to them.

Head to Settings > Devices > Headphones (or other audio device) > Toggle Connect through speakers to off

how enable headphones windows 10

Now that this is off, your computer will not recognize the headphones as a device to output to. This is why you cannot hear anything when you have headphones on!

By toggling the Connect through speakers option to off, your computer will no longer recognize the headphones as a device. No device means no sound will play through them.

You can still use them to listen to music or whatever else you want, but you will not hear any notifications or phone calls unless you connect some other audio device. This is great for taking calls in silence!

If you would like to re-enable this feature, simply turn the Connect through speakers option back on. Then, test your phone calls and see if you can hear them through the headphones. If not, try re-connecting your audio device and testing again.

How Do Noise Canceling Headphones Work

Published

on

Noise canceling headphones have been around for several years, but they have become more and more popular as time goes on. With the rise of noise canceling headphone popularity, more brands are producing them!

Noise canceling headphones work by using special technology to filter out background noise. This technology is usually in the form of specialized ear pads that either use active noise cancellation or just plain noise blocking material.

The way active noise cancellation works is pretty ingenious. Very small microphones inside the headphones pick up ambient sound, which is then processed by a tiny processor. This processor creates a sound wave that effectively cancels out the outside sound.

By doing this, only the music coming through the ear buds will be heard, making your listening experience much more pleasant. Noise canceling headphones are great for people who struggle with external noise distraction. They are also great for airplane flights, as they help reduce airplane noise and aid in sleeping.

Create opposite noise frequency

how do noise canceling headphones work

Noise canceling headphones work by creating a sound that is the opposite or inverse of the noise that enters the ear.

The headphones use what is called a digital-to-analog converter (DAC) to create a sound that is the inverse of the noise entering the ear.

This sound is then combined with the outside noise in such a way that when they mix, the outside noise is canceled out. Only the noise being blocked is removed, leaving everything else in silence.

The technology used to create this inverse sound varies depending on brand and price point. Some use special materials to make this inverse sound while others use algorithms to generate it.

Noise canceling headphones can range in price depending on quality and features, but most are not overly expensive. Some are even affordable for people of moderate income.

Send to microphone

how do noise canceling headphones work

Once the ambient sound is received by the mic, it is sent to your phone where an app processes it. The app then filters the noise out using a special algorithm.

Many apps use a special algorithm called spectral noise cancellation. This algorithm uses the frequency of the noise being received by the mic to filter it out.

For example, if someone was talking and you were listening, their voice would be processed as higher pitched and therefore eliminated from your listening experience.

The app can also use other factors such as volume and duration of noise to filter it out. This is why when you are in a loud environment your headphones seem to work better!

Noise canceling headphones are not cheap, so make sure to do your research before purchasing one! Fortunately, there are some decent ones for around $100 USD.

Compute and combine signals

how do noise canceling headphones work

In order for noise canceling headphones to work, a device has to first detect and identify noise. This is where the app comes in handy!

There are several apps that help your headphones work better. Some of these include Bose SoundLink App, Bose Connect, and Noise Canceling Headphones App.

The first one is the app that helps your headphones connect to other devices. The second one helps you control your headphones when connecting to other devices and devices connecting to you. The last one is just a fun app that tests how well your headphones cancel out noise!

Noise canceling headsets require sound signals to be computationally combined with inverse signals in order to effectively cancel out noise. This is what makes them so expensive- the materials needed to produce this effect are pricey.

Reduce or eliminate noise

how do noise canceling headphones work

Noise canceling headphones are one of the coolest technologies out there. They use small sensors to detect ambient noise, and a computer inside the headphones to filter out that noise.

They can be used to filter out airplane noise, street noise, or any other environmental noise that may disrupt your listening experience. Some models even have Bluetooth connectivity, allowing you to listen to your favorite music or podcasts over your favorite app-based streaming services like Spotify or Apple Music.

Noise canceling headphones come in all different price points depending on the quality of sound and level of noise cancellation.

Listen to music instead!

how do noise canceling headphones work

While noise canceling headphones can be a great tool, they can also be very distracting. You are paying more money for the ability to ignore the world around you, so that you can focus on your work.

If you are traveling and need to focus, listen to music instead of listening to someone else talk or music on your phone. You will have to pay more attention to what’s going on around you as you listen to music, which is the point of listening to music!

Noise canceling headphones make it easier to disconnect and distract yourself, which is why they cost more money. If you do not want that effect, then do not spend the money on them.

How To Sleep With Headphones

Published

on

Wearing headphones to bed has become a common practice, especially among young adults. With the rise of listening to music via smartphones, people have more access to music than ever before.

Music is a great way to relax and prepare for sleep. Some studies have even shown that music can improve sleep quality!

Having headphones in your ear already makes it difficult to hear outside noise. Adding music onto that makes for a very peaceful sleep.

The problem comes when people do not realize the risks of sleeping with headphones in. The most dangerous situation is when someone passes out and does not hear any emergency calls or noises.

Aside from that, pulling the headphones out while asleep can cause other issues. If they are wrapped around the neck or wrists, they may become tight and impede blood flow. If they are on the floor, then they may cause you to wake up due to feeling off balance.

There are ways to sleep with headphones on safely! This article will go over some of those ways.

Set a loud alarm

how to sleep with headphones

If you have trouble falling asleep with headphones on, then try setting a loud alarm. When the alarm goes off, you can take off your headphones and fall asleep!

This is a trick that many people use to help them sleep in uncomfortable places. By sleeping in a different place, your body recognizes that it is safe to sleep and you will get a good night’s sleep.

Sleep is one of the most important things for our health. If you struggle to sleep because you cannot listen to music or podcasts before bed, then try using this tip to help you fall asleep easier.

Some people may find it difficult to coordinate their music or podcast listening time with their bedtime. If this is the case, then try going to bed a few minutes earlier or later so that you can listen to your music or podcasts before bed.

Do not use loud music

how to sleep with headphones

While this may seem like a good idea, music or noise in general will keep you awake. Why?

Because you have to listen to the music or noise, your brain will not process the fact that you are asleep.

The fact that you are listening to something means that you are awake-your brain knows this and does not want to stop processing that fact.

To test this theory, try going to bed without music or noise and see how well you sleep. Then try sleeping with music or noise and see how well you sleep again. You will notice a difference!

It is best to have quiet, soothing music or no music at all when going to bed. Your brain will process that you are sleeping and will let down your guard so to speak.

Keep the volume low on your headphones

how to sleep with headphones

Although this may seem self-explanatory, it’s important to note that the volume on your headphones should be low. As mentioned before, there’s a risk of hearing loss if the volume is too high for prolonged periods of time.

It can be difficult to determine the appropriate volume for sleeping with headphones on, but it’s best to play it safe and have a low volume.

Experts recommend setting the volume no higher than 60% of the maximum output provided by the manufacturer. This way you will still hear enough of the music or audio to relax and fall asleep, but you will not be exposing your ears to too much noise.

Keep in mind that this varies depending on the brand of headphones you use. If you are using cheaper ones that do not have high quality sound protection, then you can probably put up the volume more.

Use a soft noise generator

how to sleep with headphones

If you find the sound of the ocean or rain too relaxing, then try a soft noise generator. You can find these online and in the app store.

Noise generators introduce a light background noise into your environment, like the sound of rain or surf, but with an adjustable volume. They are great for sleeping as you can adjust the volume to a level that is not too loud or distracting.

They are great for sleeping as they keep your mind focused on the sound instead of thinking about everything that day. They are also very relaxing, so if you are having trouble falling asleep, try investing in one!

If you have your own music and you do not want to lose the quality by reducing the volume, then turn off all of the other sounds on your phone such as notifications and set an alarm. That way, you will still hear your music but not your phone notifications.

Use white noise

how to sleep with headphones

If you struggle to sleep because of noise in your environment, you can use headphones to block out other sounds. But how do you sleep with headphones on?

For one, you can choose to listen to white noise instead of music or a podcast. White noise is an almost constant sound that blocks out other noises.

It can be the sound of a fan, the rustle of a paper bag, rainfall, or even the sound of a machine turning on and off. Any of these can help you sleep!

White noise is best because it continues even when you turn off your headphones. You can also choose to listen to white noise before bed, so that it helps you get into a relaxed state before sleep.

Use a sleeping app

how to sleep with headphones

If you do not feel comfortable using the two methods above, there is a third option. Use a sleeping app to monitor your sleep.

Many apps offer this feature for free, and some even have it as an ad-free paid feature. By having your phone next to you while you sleep, the app will monitor how long you sleep and how many times you wake up.

This is a great way to start sleeping with headphones on, as the app will tell you how well you slept!

Some of these apps offer more features such as setting a waking alarm based on how well you slept, or tracking how long it takes you to fall asleep each night. These are nice additions if you are looking for something else to track about your sleep.

Keep the headpones on all night

how to sleep with headphones

While this may seem weird, it is advised to sleep with your headphones on all night. This prevents you from having to adjust them multiple times in the night, and risk waking up your partner.

Many people have reported success in just putting the headphones on before bed and leaving them on until morning when they get up. This also helps you not worry about getting tangled in wires in the middle of the night!

Some models even have a built-up battery that keeps your music playing until the next morning so you do not have to re-charge before bed.

If you must take them off due to tangling or feeling too wired, just remember to turn them off before bed! Some models have a built-up feature that turns off the music automatically after a set time which can help with this.

Be careful when sleeping with headphones

how to sleep with headphones

While it may be tempting to fall asleep with headphones in, or even in your ear, it is not a safe idea. If you need a little white noise to sleep, try keeping the same device on standby with a playlist instead.

Many phones have a built-in setting that turns off the screen and stops all sounds after a certain time period so you do not need to set one yourself.

Removing the ability to hear sounds completely may help you get a better night’s sleep!

Some people use music to help them relax before bed, but if that makes you feel more awake instead, try switching it up. Perhaps listen to some soothing music before bed, or just take out the headphones!

Some people find that sleeping with items in their hair can be uncomfortable, so try moving them before bed.
