Now before anyone gets too excited, crude in this instance really does mean crude. These rapid pulses weren’t just good for faking polyphony, by carefully generating and cancelling thousands of tiny pulses at different volume levels the PC speaker, the natural filtering properties of the PC Speaker allow it to be used as a primitive DAC (digital to audio converter.) This meant that the PC speaker can be used to play (very) crude versions of digital sound recordings.Ī basic PC Speaker in all its glory! (Photo Credit:Hans Haase) By combining rapid pulses of different lengths, composers could give the impression of different instrument sounds and – by timing the off beats very carefully – even of instruments playing at the same time, as you can hear in the PC speaker version of Lucas Arts Monkey Island theme. Instead, the computer can trigger and cancel the speaker multiple times a second. The beauty of the computer, however, is that it doesn’t have to interact with the speaker as you or I would. If you were triggering it manually by pressing a note on a keyboard, the PC speaker would only be able to make a simple audible beeping noise. The second was that interaction between the speaker and the computer. There was no real excuse for not supporting it. The first was its ubiquity: As it was built into every PC, it was a dependable standard from that was available from the earliest days of DOS-based PCs. With that said, the PC speaker did have a couple of things going for it. If you’ve never had the good fortune to hear one, think of any old mobile phone ringtone and simplify it. ![]() Not only does it lack the separate channels you needed to make different instrument sounds, it only really has the ability to create one type of tone (a square.) In fact, Aside from the physical switch controlled by the user, it doesn’t even have any direct contro over its volume either.Įssentially, then, the computer tells it to beep, and it beeps. In the minus column, it doesn’t really have much going on in terms of features – in fact it doesn’t really have any at all. The PC speaker is, arguably, both the most and least interesting of all the PC hardware. That reassuring chirp you still hear every time you turn on a windows-based PC? Yep, that’s the PC speaker! Though PC speakers have differed in design across years and manufacturers (early PCs used magnet-driven PC speakers, later models deployed piezoelectric designs), the theory was (and is) the same: the PC Speaker is a simple speaker that is built directly into a PC’s motherboard in order to offer basic feedback while going through the boot process. Why were there so many? Were they all different products that effectively made the same sound, or were they something different? Let’s go through them! PC Speakerĭebuting with the IBM’s original 5150 in 1981, the PC speaker was the first and most basic piece of sound hardware available to PC gamers. On top of that, just look at the choices! by 1991, it wouldn’t be surprising if a game had 9 different sound options. If you weren’t aware of the settings it used to talk to your processor the whole system could lock up. Don’t think you could get away with simply knowing that your PC contained a Sound Blaster expansion card either. ![]() Back in the DOS era, installing a game meant filling in a multiple choice quiz about your machine. While console games have grown increasingly complicated since the days of plugging chunky plastic cartridges into a hidden slot, It’s now no more complicated to update a PC game on Steam than it is on an Xbox or Playstation – especially now Microsoft have decided to get in on the act with their own version of Apple’s app store. Hang on though! When you think about it, the inverse is also true. Modern games consoles, eh? With their bundled hard drives and insatiable hunger for game patches, they’re effectively just user-friendly PCs aren’t they? Yes, even you over there in the corner, Mr Switch.
