The GizWiz and the AccuVoice

GizWiz

Episode 1790

This week's gadget is the ZoVox AccuVoice, which makes the dialogue in old movies understandable again. It's different from other voice boosting systems that focus on equalization. AccuVoice combines compression, consonant-range boost, formant enhancement, minimization of bass output -- plus other proprietary techniques they prefer not to divulge. The AV157 uses 12 levels of dialogue boost – 6 stages of AccuVoice boost plus 6 stages of their new SuperVoice technology.

Scott Wilkinson and the Big Announcement

Scott Wilkinson

Episode 1790

Scott joins Leo to talk about a huge announcement at the Apple Spring Forward event. It's part of the new AppleTV (TVOS and iOS 14.5 respectively) and it's called automatic color balance. How it works is that users can pair their iPhone X to the AppleTV, and the AppleTV will calibrate your TV to make your streaming image closer to how content has been color balanced. The app will calibrate the color and gray scale by taking the phone and putting it up against your TV, and the forward-facing sensor will then tell the Apple TV to adjust its output based on what it's reading from the iPhone.

How Can I Listen to My TV With Headphones?

Joe from Marlborough, NJ

Joe would like to connect a pair of headphones to his LG TV. But when he does, the volume is very faint. Does he need some sort of amplifier? Leo says that most TVs get their audio from HDMI and the Audio Return Channel. If Joe has a home theater system or AV receiver, it's better to plug into that instead of the TV. What Leo thinks is maybe Joe needs to enable the setting in the TV menu. There are headphone amplifiers. Check out headphones.com for suggestions on which to get. There's plenty of options out there.

Episode 1786

John from Solana Beach, CA

John is having issues with power outages and is worried that it will brick his devices. Leo advises getting an uninterruptable power supply. That will guard against not only outages, but the power surges that arrive after the power comes back on. Leo likes TripLite. But there's also APS. John will want to avoid relying solely on power strips. They don't really do anything. But a UPS will preserve power until he can turn on the gas generator, or unplug devices.

Eric from Encinitas, CA

Eric wants to know what the best option for creating a 120" screen is? Larger TV panels don't seem to be affordable. Leo says that projectors are still the best option, and short-throw projectors can help when dealing with small spaces.  But microLEDs may change the game. There are microLED screens out there with sizes over 100 inches. But they are six figures right now. So it'll take a few years before the technology gets seeded down to more affordable models.
