This iOS 16.4 Trick Makes Your Phone Calls Sound Better

An old FaceTime upgrade comes to voice calls.

If you’ve downloaded iOS 16.4 to your iPhone, one new feature can help make your phone calls sound more clear. The update expands Voice Isolation to phone calls now, expanding the feature from FaceTime calls. Apple introduced Voice Isolation and Wide Spectrum to FaceTime calls with the release of iOS 15 in 2021. However, only Voice Isolation is available for phone calls at this time.

When enabled, Voice Isolation muffles distracting background noises that interrupt your phone call. That way, if you’re on a business call or catching up with friends, you won’t be interrupted by your dog’s barking or construction outside your home.

To enable Voice Isolation, you have to be on a phone call, and you won’t find the feature in Settings. But once you turn Voice Isolation on, it will stay on for all subsequent phone calls until it’s turned off.

Here’s how to activate and disable Voice Isolation for phone calls.

How to enable Voice Isolation

1. Start or answer a phone call.

2. Swipe down from the top-right corner of your screen to access your Control Center.

In your iPhone's Control Center during a phone call you will see Video Effects and Mic Mode — Mic Mode can be found in the Control Center during a phone call.

3. Tap Mic Mode near the top-right corner of your screen.

4. Tap Voice Isolation.

Pro tip: Instead of turning this feature on during a call with someone else, you can call yourself and enable Voice Isolation by following the steps above.

To disable Voice Isolation, follow the same steps above and tap Standard in Mic Mode. This will return your microphone back to its default setting.

What’s Wide Spectrum?

Alongside Voice Isolation in Mic Mode is Wide Spectrum. Unlike Voice Isolation — which muffles background sounds — Wide Spectrum amplifies background sounds without affecting your voice.

Mic Mode displays a message that Wide Spectrum is currently unavailable — A message in Mic Mode says Wide Spectrum isn’t available on phone calls.

Wide Spectrum is useful for calls with multiple people on one phone line. That way, everyone can be heard, not just the person holding the phone.

Currently, Wide Spectrum is only available for FaceTime calls, not phone calls. But, since the feature is still present in Mic Mode when accessed during a phone call, this feature might become available for phone calls in the future.

Mario Kart World Direct: Live Nintendo Switch 2 News

Nintendo Fails to Justify $80 Price Tag in Mario Kart World Direct

Nintendo still hasn’t explained why it’s charging more for the game.

Nintendo held its Mario Kart World Direct on Thursday morning to show off the flagship game that’ll launch with the Switch 2 in June. But even as the company showed off the game’s new features, most people watching wanted one thing: For Nintendo to lower the price.

Mario Kart World received backlash when it was revealed to have an $80 price tag after the Switch 2 reveal event on April 2. Those interested in the Switch successor are excited about the new games but concerned that its higher price may be the start of a new trend. There are already concerns about the Switch 2’s price and whether it will increase from the announced $450 mark following recently instituted tariffs, which caused a delay to preorders for the US. The price of new games currently tops at $70 across different platforms.

While Nintendo didn’t justify the price, the showcase did go over all the details about the game.

Mario Kart World will be the biggest Mario Kart game, giving players the freedom to travel across the map on their own. This is the first time racers can freely roam with no need to stay on the track — unless, of course, they want to win the race.

The Mario Kart World Direct showed off the game’s new courses: Mario Bros. Circuit, Crown City, Salty Salty Speedway, Starview Peak and Boo Cinema. Reimagined tracks from older games will also be included. There are three new racers: Goomba, Spike and Cow.

It couldn’t be a Mario Kart game without new items to use during a race. Those items include the Coin Shell, which can knock out opponents as well as drop coins, the Ice Flower to freeze other racers, the Mega Mushroom to grow huge to bump everyone out of the way and the Feather to make some big jumps. There’s also Kamek, the longtime magical enemy of Mario who will help a racer by transforming everyone else on the course.

There are two racing tours: Grand Prix and Knockout Tour. In Grand Prix, there are three cups to choose from — Mushroom, Flower, Star — and players compete in multiple races to earn points in order to win the cup. Nintendo teased that after completing the Grand Prix, the beloved Rainbow Road track might be unlocked. Knockout Tour is similar to Grand Prix except that you have to place or else get kicked out of the next race. In both tours, players will have to drive from one track to another.

New techniques are making their debut in #MarioKartWorld!

During that roaming time between races, players can experience the Mario Kart World map. There are hidden coins and panels, as well as P buttons that will start quests to collect blue coins in a certain amount of time. The world also has Yoshi drive-thrus, where players can pick up food that will unlock new outfits for characters.

One of the big new additions in Mario Kart World is the Rewind function. During a race, a player can rewind themselves to make a jump or reach a platform. However, if done during a race, all the other racers will continue forward, which could cost you the race.

For multiplayer, one person with Mario Kart World can let up to four players play on the same system via split screen. Online races will support up to 24 players, and with the Switch 2 Camera and GameChat, players racing against each other can see their faces positioned over their characters while playing.

Mario Kart World launches on June 5 for $80 with the Switch 2. There is a Switch 2 Mario Kart World Bundle for $500, and during the Direct, Nintendo mentioned that this bundle will be available for a limited time.
