The Sounds Of The World, One Random Album At A Time

In the streaming era it’s easy to forget that there’s still a lot of stuff being broadcast over the radio for anyone who cares enough to dial in their receiver. Give me an antenna big enough and a tower on which to place it, and I shall listen to the world.

Of course, so you can’t actually listen to everything being blasted out all over the planet yourself. But if you’d like to at least have a little taste, check out Impermanence Series A — a project by [Sam Scorsby] that randomly combines bits and pieces of audio pulled down from shortwave and FM broadcasts with some web streams, live microphones, and even a bit of the Internet Archive each day into a one of a kind album. We’re not sure we’d call it music, exactly. But it’s certainly fascinating to listen to, a bit like randomly spinning the dial on a planet-wide radio receiver.

[Sam] has shared the Python scripts that pull together each day’s album, and he’s not shy about the fact that the project was created with the help of artificial intelligence tools. In fact, that’s sort of the point. [Sam] puts himself somewhere in the middle when it comes to the current debate over AI, and acknowledges that while computers are good at processing raw data, it still takes a human touch to put it all into context.

So each day [Sam] will listen to the latest computer-generated album and pick his favorite tracks, and once the project has run its course, he’ll put together a human-curated “Best Of” collection. Man and machine working together, each doing what they do best.

We know something of opinionated folks on the Internet, and our experience tells us that Impermanence Series A is unlikely to change anyone’s minds when it comes to AI. But we do appreciate the thoughtful approach [Sam] has taken with the project, and look forward to hearing what he comes up with in the end.

The PC Speaker Lives On As A New Album

The speaker in the original IBM PC is nearly the worst electronic musical instrument ever created. This isn’t because amazing works of art were never created for the PC speaker; no, that’s been done, and it’s amazing. The PC speaker is terrible because of how limited it is. It does one note at a time, only square waves, driven by an 8253 Programmable Interval Timer. Polyphony? Forget about it. Volume control? Nope. These aren’t really shortcomings, because music is art, and you can write a novel without using the letter ‘E’; the trick is in how you manage to do it.

[shiru8bit] took a deep dive into the PC speaker and decided to make an album. The video, with the completely necessary CRT graphic display, can be seen here. This alone is impressive, but what makes it amazing is how this album happened.

If you want to play more than a simple melody on a PC speaker, there are two or two and a half ways to do it. The first is to (virtually) set up two (or more) channels, loaded up with frequency values. At set intervals, the CPU changes the 8253 to output one frequency, then in the next chunk of time, sets the 8253 to another frequency. It sounds ‘bubbly’ for lack of a better term, but the results can be amazing; just check out the PC speaker version of Monkey Island. The 8253 can also be turned into a rudimentary DAC, but this was a rare technique thanks to patents, and by the time the patents expired everyone already had a Soundblaster. Oh well.

[shiru8bit]’s album uses the first technique, cycling through monophonic square waves at 120 Hz, but the real trick here is how the individual channels were composed. This required creating a VSTi plugin called PCSPE. This emulates a PC speaker, and sort of, kind of, implements arpeggios, pitch, and priority of different channels. Effectively, it’s a PC Speaker tracker.

The result is classic chiptune goodness, made on an instrument that really shouldn’t be used for music. It can be played on DosBox, but the weirdness of the real hardware including transients and the inefficiencies of a tiny speaker make real hardware almost a necessity here. You can check out the entire album below.

The Nest: Album Release Hidden In A Rock

First there were vinyl records, then came cassettes, CDs, those failed audio-on-DVD formats, and then downloads. To quote the band, [Bateleur], “you can’t pay someone to take a CD these days.” So how do you release your new album? By hiding a Raspberry Pi in a semi-transparent fake rock on a mountainous cliff, and requiring a secret whistle to enable it, naturally.

Once activated, you’ll be able to plug into the USB port and download the album, or sit there on a remote hillside cliff overlooking the ocean and enjoy the new tunes. Because there’s a headphone jack in the rock, naturally. Besides being a cool hack, we think that putting people in the right physical and mental space for a serious listening is brilliant. Watch the video embedded below for an idea of the making of and a view from the site.

Laser-cut Album Released

In some alternate universe, where laser cutters and phonographs are more common than MP3 players, it makes a ton of sense to release laser-cutter files for your band’s new album (Translated). In this universe, it’s wacky and awesome.

The new EP from ASIC, alias [Patric] from Fablab Zürich, is out as PDF before it’s out in other forms of digital download, and the trailer video (embedded below the break) looks fantastic.

The release draws on this Instructable by Amanda Ghassaei to turn the music into PDFs suitable for feeding into a laser cutter, and we think it’s classy that she gets a shout-out on the label’s release page.  Everything else about the album will be released under a Creative Commons license to boot.
