Online Museum Is Preserving 'Endangered' Sounds for Future Generations

The plunk of typewriter keys. The buzz of a vintage intercom. The whir of a rotary-dial phone. Your familiarity with these sounds probably depends on your age.

One by one, a project spotted by Fast Company is cataloguing the sounds made by outdated objects that have faded from our collective memory. Called Conserve the Sound, it's “an online museum for vanishing and endangered sounds,” according to a description on the project's website. Most of them are vintage pieces of technology, but a foldable city map and a window crank handle for a car have also been included.

The project is the brainchild of Germans Daniel Chun and Jan Derksen, who own a media agency and argue that “sound branding” will play a larger role in the future.

Included in this museum of soon-to-be-forgotten sounds are items from the early 1900s up through the 2000s. You’ll hear the sounds made by a GAF View-Master from the ‘60s, the oddly shaped Weltron cassette recorder from the ‘70s, a Sony Walkman from the ‘80s, and a Leica Pradovit slide projector from the ‘90s.

Among the more recent items are two cameras: a Polaroid and a Canon EOS 3000N, both from the early 2000s. In other words, there’s something to make just about everyone feel old.

Google Creates First AI Doodle for Bach’s Birthday

Although there’s some debate about Johann Sebastian Bach’s exact birth date, today is roughly the 334th anniversary of the famous composer’s birth. In celebration of Bach’s contributions to a genre that would later be called classical music, Google created a Doodle that lets users create a song in Bach’s signature style.

Google has created musical Doodles before, but what sets this one apart is that it’s the first-ever Doodle powered by artificial intelligence, according to Newsweek. In this case, users create a simple melody by choosing their preferred notes on a musical staff, then increasing or decreasing the pace (measured in beats per minute, or BPM) or changing the key, if desired. Once satisfied, all they have to do is hit the “harmonize” button and let AI create a more sophisticated tune.

Fortunately for Google, there was a lot of material to draw from. Bach was a busy man, creating more than 1100 compositions in his lifetime (while also finding time to father 20 children). However, for this Doodle, a machine-learning model called Coconet was fed a portion of his oeuvre—306 harmonies in total. In addition to being trained to recognize the musical patterns in Bach's work, the model is also capable of creating harmonies, smooth transitions, and compositions from scratch.

“So when you create a melody of your own on the model in the Doodle, it harmonizes that melody in Bach's specific style,” Google explained in a statement. And just for fun, there’s a feature that lets you hear what the harmony would sound like in a modern rock style.

For a behind-the-scenes look of how the Bach Doodle was made, from both an artistic and technical perspective, check out Google’s video below.

What's the Difference Between a Router and a Modem?

Despite using it every day, the internet is still a mystery to many of its users. If asked to explain how your home internet connection works, you may start with your router and modem. Both devices are essential to setting up a wireless network, but they serve distinct functions. Here are the major differences between the two pieces of hardware that make home internet run.

What is a Modem?

The modem is your home's gateway to the World Wide Web. It's often a skinny box with a row of LED icons on the front that tell you if it's on and connected to the internet. The name is short for modulator-demodulator—a phrase left over from the days of dial-up when modems worked by modulating telephone signals into frequencies that could send digital information.

Today, most modems use broadband connections like cable or satellite to transmit data. There are different types of modems built to fit different connections. If your internet service provider (ISP) uses cable or fiber internet, you'll need to plug a cable into the back of your modem, and if you still use a digital subscriber line (DSL), you'll have to plug in a phone line.

What is a Router?

You can connect to the internet with just a modem as long as you don't mind plugging your device directly into the Ethernet port. But if you want to provide internet to all the laptops, desktops, and smartphones in your home at the same time, you'll need a router.

Routers usually lie flat and have antennas sticking out of them. The router hooks up to your modem via an Ethernet cable and acts as a conduit between the direct internet and your home network. After connecting your devices, the router "routes" your modem's networking traffic their way, either through Ethernet wires or wirelessly through Wi-Fi (that's what the antennas are for). The router also works in the other direction by routing data sent from your computer back to the web.

Why Knowing the Difference Matters

When they've been sitting in the same spot in your home for years, it's easy to think of your router and modem as basically the same thing. But it's worth knowing the difference—especially if you care about improving your internet connection. Now that you know the router is what directs Wi-Fi signals, you can boost your home network by placing it in a central location away from electronic appliances. And as long as it doesn't interfere with the router, feel free to hide your modem behind a houseplant.
