Suggested April 2024 How To Find And Use Snapchat’s New Backgrounds And Voice Filters.
If you have the feeling Snapchat adds a new feature every few weeks, you’re not wrong, especially at the moment. It has only been a couple of weeks since the release of Snap Maps and now Snapchat has released new voice filters and backgrounds. This guide will show you where to find the newly added features and how to use them.
How to Find and Use Snapchats Snap Map.
Snapchat always seems to be a step ahead of the curb when it comes to new features and innovation, leaving Facebook and Instagram scrambling to implement an almost clone like feature at a later date. With the dust only just settling on the last big Snapchat feature Snap Maps, it’s quite surprising to see another feature added so quickly. Perhaps this is a strategy to overwhelm Facebook and Instagram with clone projects…. Whatever Snapchats reason for this, it’s always a great outcome for users, new features usually means more fun, so let’s find out a little more about Snapchat Backgrounds and Voice Filters.
Before we begin showing you how to use the new features, you will need to make sure you have the latest version of Snapchat installed on your mobile device, version 10.12.0.0. If you don’t, you won’t be able to use voice filters or backgrounds. To get the latest version, simply open your phone or tablet’s app store and check for updates. Once you have Snapchat version 10.12.0.0 you’ll have full access to all the features, regardless of whereabouts in the world you live.The Other Feature we Didn’t Mention in the Title. (Snap Links)
As well as adding backgrounds and voice filters, Snapchat has also added the ability to share links with friends in Snaps. This is probably the most useful feature included in the recent update, however, it is more a utility than a fun feature, never the less, it’s a handy option to have. To Share a link in a Snap, tap the new Paperclip icon in the vertical toolkit menu (the same toolbar that allows you to add text to snaps)
Once you’ve tapped the paperclip icon, you will need to give Snapchat permission to use the clipboard, after you have approved access, you can manually type a URL or more easily paste one into the box. When you have finished putting together your link inclusive snap, you can send it in the same manner as you would any other snap.Finding and Using Snapchat Backgrounds.
Each time Snapchat’s features list grows, the user interface usually become slightly more crowded, making some features near impossible to find. Unless you know exactly where you’re looking or more likely if you stumble on to them! The first feature we will be locating, is the Snap Backgrounds feature, which allows you to add custom backgrounds to your snaps.
To find Snapchat backgrounds you will need to take a snap, then tap the Scissors icon in the vertical toolkit menu (the same toolbar that allows you to add text to snaps) on this submenu look for the newly added backdrop icon, it looks like a square with slanted lines through it. Now, all you have to do is choose a background you think works with your image, once that’s done you can send your snap. For now though, the background options are pretty boring, however, Snapchat will no doubt add more as time goes on.Finding and Using Snapchat Voice Filters.
The last feature and the most interesting are the newly added Snapchat Voice Filters, which allow you to change your voice to a variety of crazy sounding novelty characters. One of the more notable and highly annoying options is the Chipmunk voice, which will no doubt be a fantastic way to drive your friends mad. There are a few others you can choose from, including a sci-fi robot.
To use the new Snapchat Voice filters you will need to record a Snap, (with voice included obviously) then tap the speaker icon at the bottom of the screen. Finally, all you need to do is choose the effect you like and you are done, you can now send the snap to all your friends or post it to your Snap following.

Presenting the best side of you is an irrepressible instinct, and it applies to physical appearance. Filters and effects on TikTok are tools that help you upscale the visual impact of a video by fusing it with your own creativity.
In this article, let’s break down the function of filters and effects, where to find them, and how to use them.
How to add filters to a TikTok video
Launch the TikTok app and tap the Create “+” button.
It opens the app cam. The icon for filters is “three-converging-circles” and is found in the vertical list of editing tools on the right side of the screen. You may implement (most) filters before or after recording either photos or videos in the Quick or Camera modes, or even to the photos uploaded from the image library.
Tap Filters to view the choices.
Filters are classified on the basis of applicability into Portrait (for faces or people), Landscape (for places or other visuals of a broader panorama), Food (clearly to improve the aesthetic appeal of food items), and Vibe (for more thematic filming like a vignette filter for vintage vibe). The red circle around a filter indicates its selected state.
You can also adjust the intensity of the filter’s effects using the slider bar.
The screenshot below shows an image as seen through the Landscape V6 filter implemented to the extent of 80% to increase the saturation of red color in the feed.
Tap Management to add or remove filters from the available categories.
Apart from the filters with the dimmed checkboxes (which represent the default filters), you can check or uncheck any filter to add or remove them from the filters shortcut.

TikTok Beautify versus Enhance modes
While filters serve as cool lenses to transform the visual quality on an unbiased scale, TikTok also has certain filters that form a beauty mode. These are not titled as filters but called Beautify on TikTok app for iOS or Enhance on TikTok app for Android.
Beautify holds a whole belt of various brushes to give your facial features a virtual transformation. It has tools to smoothen the skin texture, whiten your teeth, or even tweak your facial contours to name a few. In addition, it also includes necessary makeup tools like foundation or lipstick to finish up the look.
If we compare both these enhancements effects side by side, Enhance (on Android app) is a cut above with its full-fledged make-up and beautifying tools that offer a whole range of unique “face” filters to alter everything from natural to either of the extreme ends.
Enhance has an additional tab titled Make-up which has 8 make-up lenses (2 for men) to glam up your look. In the screenshot below, you can see the effect of “Romantic” make-up look on my eye — the original brown eye color is superimposed with a green iris, and even a hint of mascara effect is added to the lashes. Various changes are applied to all the features and it could be simple and inconsequential as proffered by the Nature look or make for a dramatic change when the Glow look is used.

TikTok Filters vs Effects
In the TikTok universe, filters and effects are terms often used interchangeably. Because they don’t contradict in function, but even share close relations, it is not necessarily wrong if you identify one for the other. However, there is an inherent variation in the overall impact of filters and effects as independent tools and let’s see take a close look at it.
Filters on TikTok are layers imposed on a video/image as a whole. We can relate it to the color filters available on editing software like the sepia mode you apply to an image to give it a warmer tone and imbue it with a vintage spirit. Filters are predefined and consistent; each one could be understood as a lens that transforms the view according to their innate attributes — hence the overall result is not limited to a particular region but to the video or image as a whole.
Filters are available are a part of the editing tool in the TikTok editing function, and they are differentiated into various categories like filters for portraits or images of landscapes, or food. They are preset and infused with varying color saturation to evoke a certain mood or feeling.
The line separating filters and effects as tools blur when effects that emulate a filter in function get added to the app’s roster. For instance, the Euphoria filter on TikTok is accessible to uses on the app as an effect — this comes down to one reason, filters are preset lenses available as an editing tool on TikTok; on the other hand, the new filters could be added by eligible users to the app get registered as effects in it. As a result, the real point of differentiation is fine, or almost invisible when we consider these terms on the basis of application than technical definition.
Now, let’s take a look at where to find these tools and how to use them to enhance the quality of our content.
How to add Effects to a TikTok video
Effects serve a highly interactive role in pioneering or indulging in TikTok trends. They give your videos that much-needed amplification that can not be rendered by the simple color overlay effects of preset filters.
Have you ever felt at a loss as to where to find all these cool effects that are so awesomely employed by the vibrant community of TikTok creators? Well, you no longer have to feel left out or clueless, because, we are about to explore the various ways to locate and use any of the available Effects on the apps.
1. Find effects from the Effects box in the app camera
The most straightforward way is to scavenge for interactive effects straight in the Effects box in the app’s create page.
Launch TikTok and tap the Create “+” button.
The popup shows a whole spectrum of effects to choose from. The effects which you have previously favorited are available under the first tab.
Slide the tabs to view all the subcategories or scroll down to explore the various effects listed under each group. The amount of fun you can have with TikTok effects is immeasurable… like playing with this little AR Turtle that jumped out of my phone onto the screen of my PC.
If you use an Android phone, the TikTok app even supports “searching” within the Effects. All you have to do is enter keywords like “zoom”, “green screen”, “3D”, etc. to get quick access to a list of all the effects that fall under it.
2. Use effects from a currently playing video
When you see these enthralling trends that use intriguing effects, it is only natural for your curiosity to get piqued. Perhaps, you might even get tempted to try the effect yourself. But, where to find them? Of course, you can search for the effect by name if you know it, but most often than not, the names of effects get overshadowed by other elements in the trending video.
Worry not, because the answer is available in plain view for you to go grab. When you see a video that you think contains an interesting effect or filter, you can find them in the effects tagged to the post.
All the effects get automatically tagged to the post. Tap the effect tag.
If you wish to use the effect right away, tap Try this effect.
Booked effects are grouped under a separate, quick access tab under effects. To access the “favorited” effects, tap the + Create button.
Now, tap Effects located at the left side of the red record button.
The quickest method to use an effect immediately is even simpler. Tap the ellipsis button on the right side of the screen.
Tap Use this effect to carry it directly over to your create page.
Tip: Search for effects in TikTok Discover
You can also resort to the TikTok Discover feed to dredge up an effect used in a trend based on your keyword query.
Tap any video from the results.
Tap Try this effect to immediately jump to the create page with the effect.
Filters and effects are almost the same when it comes to functionality, the differentiation is incorporated to delineate the preset filters that offer basic color overlays from the interactive filters that show more versatility in terms of the ability to impress viewers. However, effects such as Euphoria mentioned above are fundamentally filters that also showcase preset attributes. Hence, it all comes down to where to find them and what they offer.
When you just get your first iPhone, you’ll find that it’s super easy to use. It has a nicely organized Home screen and a simple way to find your Settings. But there are little tips and tricks that can take a while to learn, like how to use your Today View and Notification Center effectively.
That’s why iDB is here to help with our “New to iPhone” series. If you fall into the new iPhone user group, this series, along with this article, are for you. Here’s how to use the Today View and Notification Center on your iPhone.Today View and Notification Center What exactly are the Today View and Notification Center?
The Today View is a unique spot that contains widgets for apps you choose. For things you use frequently like your to-do list, calendar, or weather, you can pop a widget in the Today View area. Accessing Today is done by swiping right from the left edge of the Home or Lock screen.
The Notification Center holds, well, your notifications. Whether its new emails, app alerts, or text message notifications, you can find it all in the Notification Center. Accessing the Notification Center is done with a simple swipe downward on any screen.Accessing Today View and Notification Center on the Lock screen
You can decide whether or not you want access to Today View and the Notification Center from your Lock screen. If you do, it takes a few taps to make it happen.
1) Open Settings.
2) Select Touch ID & Passcode or Face ID & Passcode for iPhone X and later.
3) Scroll down to the Allow Access When Locked section and turn on the toggles for Today View and/or Notification Center.Customizing the Today View
Taking a bit of time to customize the Today View on your iPhone is worth it because it gives you what you use most often in an easily accessible spot.Adding, removing, and rearranging widgets
Access Today View, scroll to the very bottom, and tap Edit. This takes you to the Add Widgets screen.
At the top, you’ll see the widgets currently in your Today View and at the bottom are the additional widgets you can add.
To remove a widget from Today View, tap the minus sign in red, and tap Remove.
To add a widget, tap the plus sign in green.
To rearrange widgets, tap the three-line icon, drag, and release.
When you browse through widgets you can add at the bottom, you’ll notice that some apps offer more than one type of widget. For instance, the Maps app lets you pick Destinations, Nearby, or Transit widgets.
Third-party apps may provide different widgets as well. For example, Google Maps has Directions, Local Guides, Traffic, Transit Departures, and Travel Times widgets. So depending on the app, you can check out different widget options. For something cool, check out these iPhone weather widgets.
When you finish adding, removing, or rearranging your widgets, tap Done on the top.Using the Notification Center
Deciding what you see in the Notification Center is a good way to make sure you’re getting the notifications you want.
You might now want that area filled up with game notifications or other app alerts that you don’t care about.
To adjust the notifications you see, head to your Settings and select Notifications. For each app in your list, you can decide whether or not an alert displays in the Notification Center. Tap an app and then select or deselect Notification Center.
It can be a tedious task to do this for every app in the list that you turn on notifications for, but worth it if you want to keep your Notification Center in order.Actions in the Notification Center
When you swipe to access your Notification Center, you can also perform actions on those alerts.
Tap or swipe right to open the app or swipe left to manage that app’s notifications, view a preview of the notification, or clear all notifications for that app.
To clear out your Notification Center, tap the X at the top.Wrapping it up
Hopefully this how-to on using your iPhone’s Today View and Notification Center will help you set them up exactly as you want them.

Seeing Space and Hearing Time Scientists find new brain network that sheds light on attention and memory
Samantha Michalka and David Somers identified a previously unknown attention network in the brain. Their work appears in the journal Neuron. Photo by Mike Spencer
Humans abound with remarkable skills: we write novels, build bridges, compose symphonies, and even navigate Boston traffic. But despite our mental prowess, we share a surprising deficit: our working memory can track only four items at one time.
“Would you buy a computer with a RAM capacity of 4?” asks David Somers, professor and chair of the Department of Psychological & Brain Sciences. “Not 4 MB or GB or 4K—just 4. So how the heck do humans do all this stuff?”
“There’s so much information out there, and our brains are very limited in what we’re able to process,” adds Samantha Michalka, a postdoctoral fellow at the Center for Computational Neuroscience & Neural Technology. “We desperately need attention to function in the world.”
Michalka is lead author and Somers is senior author of a new study that sheds light on this enduring mystery of neuroscience: how humans achieve so much with such limited attention. Funded by the National Science Foundation (NSF) and the National Institutes of Health (NIH), the work identifies a previously unknown attention network in the brain. It also reveals that our working memory for space and time can recruit our extraordinary visual and auditory processing networks when needed. The research appeared on August 19, 2024, in the journal Neuron.
Prior to this work, scientists believed that visual information from the eyes and auditory information from the ears merged before reaching the frontal lobes, where abstract thought occurs. The team of BU scientists, which also included Auditory Neuroscience Laboratory Director Barbara Shinn-Cunningham, performed functional MRI experiments to test the conventional wisdom. The experiments revealed that what was thought to be one large attention network in the frontal lobe is actually two interleaved attention networks, one supporting vision and one supporting hearing. “So instead of talking about a single attention network,” says Somers, “we now need to talk about a visual attention network and an auditory attention network that work together.”
The scientists wondered just how closely the networks cooperate, and when. “Our visual system is terrific at processing space, but just okay at processing time,” says Somers. “But our auditory system is amazing for processing time, but not very good for space.” In other words, when a person tries to locate something in space, like a speeding ambulance, vision trumps hearing. But try to keep track of intervals in time, and hearing wins.
But what happens when you have to use the inferior system? For instance, what if you had to remember the location of several noises, with no visible cues? Would your overtaxed auditory system “borrow” spatial expertise from the more competent vision regions? That’s what the scientists wanted to find out. This led to another set of experiments, where they asked subjects to complete spatial tasks with their hearing, and timing tasks with their vision. The experiments showed that the two networks cooperate closely, with the visual network helping us understand what’s happening in space, and the auditory network helping us understand events occurring over time.
“When people need to remember the location of multiple sounds, the brain piggybacks on this visual-spatial system,” says Michalka. “And the same thing is true in reverse: When you need to remember a timing pattern in vision, then we see the brain piggybacking on this auditory system.”
“In a sense, we see space even if the spatial information is not visual, and we hear timing and rhythms even if the timing information is not auditory,” adds Somers. “In this way, vision and hearing each help boost each other’s capabilities.”
The team’s work adds to the overall understanding of how the human brain is organized. Fine-tuning our map of the brain may eventually lead to a deeper understanding of attention disorders and better tools for predicting the outcome of brain injuries.
Michalka says scientists are especially interested in how the frontal cortex—the hub of attention and planning—adapts to support cognition. “Because we think a lot of higher-level cognitive processes are going on there, it’s much more complicated to study, and so we need to get more and more clever in the way that we approach it,” says Michalka. “The frontal cortex is one of the final frontiers.”
