The Lofi Magic of VHS Audio [video]

They're what got me hooked on getting into playing with cassette sounds. Every time I listen to them I'm transported and get stuck in an uncomfortable wooden chair in elementary school watching National Film Board documentaries and I love it. It pushed me to this sound https://pl-10.x.burns.fm/?t=15fb486da703a7ae565d2dcd0113908e

There's a duplication company in Canada (they're easy to find...) that sells NOS, custom housed tapes, and all kinds of related production materials. There aren't many new options out there for working with cassette tapes, but if you can find a used deck in good shape (or there are new Tascam/TEAC machines) then you can have some real fun still. They also deal in some VHS.

It pretty much was just like that (I was there). One of my favorite "biographical" movies that nobody's ever heard of is Explorers:

The "More like this" section at the bottom has some other goodies, although a bit campy: Flight of the Navigator, *batteries not included, Short Circuit, Harry and the Hendersons, etc. Mainstream movies like The Goonies and The Breakfast Club are uncannily accurate. My friends and I basically rode BMXs and played Nintendo and drank Mtn Dew by the pool while REM played on the radio. We had analogs for everything today except the internet and cell phones, and much of it was actually more functional (didn't require instructions). And politics was a joke back then, like it was common knowledge that Reaganomics would dismantle Social Security and leave no money for Gen X (which hadn't been named yet) but we were rapidly heading for the 2015 Back to the Future Part II where we'd have our own fusion reactors so it wouldn't matter anyway.

Oh and my friend had a VCR that could pause without jittering, because in most models the magnetic head had to move slightly to pick up a signal from the tape. My other friend had access to a Video Toaster (can't remember if it was at the A/V club or a local TV station) that could add words and FX. But really the best work had the smeary transitions where we pressed record. And mixtapes often had part of the radio station's jingle or missed the first few seconds of the song. Everything was a bit dreamier because we were doing original things ourselves, not watching other people do it on YouTube. That's probably what I miss most.

"it's the stuff dreams are made of"! also, flight of the navigator is an amazing movie https://archive.org/details/FlightOfTheNavigator1986

The video makes a good comparison in the frequency domain between the original and processed audio, but the high and low frequency attenuation is only half the story.

The other key part of the VHS sound is the pitch modulation caused by slight inconsistencies in the speed of the tape going past the heads. In a synthesizer, this can be mimicked (and often is, in "lo-fi" presets) with a sine wave modulating the oscillator frequencies.

Still, if you want to get that full, dreamy VHS shimmer, you don't necessarily have to dub your audio onto an actual machine. There are software emulations out there, my favorite of which is a user-created Reaktor effect called VHS Audio Degradation Suite: https://www.native-instruments.com/en/reaktor-community/reak... It gives you full control over an exhaustive set of VHS attributes, from flutter and wow to distortion and noise.
