Demonstration of “strobelight” technology

With the phasing out of monitors and televisions using cathode ray tube technology, a void was created for users who wanted the ability to clearly see objects or text moving on the screen, being able to distinguish information even at high speeds. Fortunately, for at least 10 years a (partial, but very good) replacement has been developed, namely by implementing “strobe lights” that can turn off and on again 60 times per second (or more often). Next, we will see how this phenomenon can be observed demonstratively on any device with a screen.

Get creative with Sound by Layering Tracks in voice memos

On iPhone 16 Pro and iPhone 16 Pro Max, the Voice Memos app includes a recording feature that lets you record a second audio layer – like vocals, narration, or an extra instrument – over an existing memo, all without needing headphones. Keep reading to learn how it’s done.

Thanks to the A18 Pro chip’s advanced audio processing, iPhone 16 Pro models can play an original Voice Memo recording through the speakers while simultaneously isolating and capturing new audio cleanly. Whether you’re capturing a quick harmony, adding context to a saved memo, or simply experimenting with sound, layering recordings like this offers a seamless way to capture richer ideas.

Once finished, layered recordings can be edited, separated, and fine-tuned directly on the iPhone or easily transferred to apps like Logic Pro for more advanced mixing. For musicians, podcasters, or anyone who regularly records voice notes, it’s a bit like having a mini studio setup right in your pocket. Here’s how to make your first layered recording.
