I don't get why Apple’s multitrack Voice Memos require an iPhone 16 Pro

Apple’s recent iPhone event brought some nifty ideas, from the camera button to a reinvention of Google Lens and beyond. The company also announced that it's bringing simple multitrack recording to Voice Memos. This was particularly exciting for me since, well, I use Voice Memos a lot. I have nearly 500 of these little recordings that were made during the lifetime of my iPhone 14 Pro and thousands more in the cloud. You never know when you’ll need a random tune you hummed while waiting for the subway in 2013.

So this feature felt tailor-made for me. I write songs. I play guitar. I do everything that lady in the commercial does, including opening the fridge late at night for no real reason.

Then reality hit. This isn’t a software update that will hit all iPhone models. It’s tied to the ultra-premium iPhone 16 Pro, which starts at a cool $1,000. I don’t really want to upgrade right now, so the dream of singing over an acoustic guitar track right on the Voice Memos app is dead on arrival.

Why is this particular feature walled behind the iPhone 16 Pro? It’s a simple multitrack recording function. From the ad, it looks like the app can’t even layer more than two tracks at a time. This can’t exactly be taxing that A18 Pro chip, especially when the phone can also handle 4K/120 FPS video recording in Dolby Vision.

Pro Tools, a popular digital audio workstation, was first introduced in 1991. This was two years before Intel released the Pentium chip. Computers of that era had no trouble layering tracks. For a bit of reference, last year’s A17 Pro chip had around 19 billion transistors. An original Pentium chip had around three million. In other words, a modern smartphone chip is around 6,300 times more powerful than a 1993 Pentium-based PC.

So let us layer tracks on Voice Memos, Apple! It can't be that complicated. I’ve been using dedicated multitrack apps ever since the iPhone 3. Apple throws GarageBand in with every iPhone. Both GarageBand and third-party recording apps have a place, sure, but nothing beats the quickness and ease-of-use of Voice Memos. It’d sure be great to be able to make a quick-and-dirty acoustic demo of a song and send it out to someone without having to navigate a fairly complicated interface.

Yeah. I see the elephant in the room. There’s a part of the ad that I’ve been avoiding. The woman records the vocal layer over the guitar track without wearing headphones. She just sang into the phone while standing in front of that refrigerator. Now, that’s something old-school Pentiums could not do. There’s some microphone placement wizardry going on there, along with machine learning algorithms that reduce unwanted ambient noise. The iPhone 16 Pro has a brand-new microphone array, so I get that older models might not be able handle this particular part of the equation.

But who cares? That’s a really neat feature. It’s also completely unnecessary. If you’re reading this, you are likely already wearing earbuds/headphones or have some within reach. Record the first track without the headphones. Record the secondary layer while wearing headphones. That’s it. Problem solved. You can even do it in front of the refrigerator.

Also, both the base-level iPhone 16 and the Pro support Audio Mix, which lets people adjust various sound levels from various sources after capturing video. This is done without the new Studio Mics on the iPhone 16 Pro and seems to reduce ambient noise in a similar way. So it could be possible that there's a software solution here to handle even that elephant in the room. After all, the company credits "powerful machine learning algorithms" for this tech — if it can erase environmental wind noise, surely it can handle music playing in the background?

So I am once again asking for Apple to let the rest of us play around with multitrack recording on Voice Memos. There’s no reason every older iPhone model couldn’t compute its way to a simple guitar/vocal two-track wav file. Pop the feature into a software update. I hear there’s one for iOS 18 coming really soon, and another for Apple Intelligence after that.
