> Computers are a really hostile environment for audio
My first thought was the author should be happy that they don't live back in the bad old days of computing. Audible noise was the norm, even when you were playing audio. At least for PCs with sound cards. I don't recall the situation being quite as bad on other platforms. Modern PCs are much better on this front.
I have vague recollections of a quote from the Computer Chronicles in the mid-1990's. It went to the effect of turning a $2000 computer into a $200 stereo ...
- tonyarkles 2y agoAnd don’t forget RFI if a cell phone was close to your speakers. You’d hear a noise right before your phone started to ring!
- andrecarini 2y agoI could even hear an actual radio broadcast coming off my speakers whenever they were powered. Maddening!
- cafeinux 2y agoThis kind of thing amazes me. Radio is such a simple, yet omnipresent, technology that even something not made to listen to radio can accidentally catch and play the signal like an actual radio player would. I sure hope it's never going away.
- K0balt 2y agoWhen I was growing up, we lived within 6km line of sight from a powerful AM broadcaster on 660KHZ. By some stroke of fortune, our woodstove smoke pipe and the tinfoil backed insulation of the house, Along with the grounded base but rusty bolted on top of the woodstove created some kind of resonant receiver at that frequency. It would generate sufficient voltage to deliver the occasional electrical shock, which was very mysterious because we had no idea how this stove could shock you, even when the mains were turned off. The mystery of the source of the power was shocks when we built a wire drying rack above the stove, which acted as a sound transducer. With the glove rack, we were treated to 24/7 programming, mostly community oriented stuff like “problem corner”(community issue discussion) bush relay messages for remote listeners outside of telephone reach, “tradio” (call in radio Craigslist, basically), news shows, talk shows, and some occasional music. To me, it was just completely normal, never having known anything else besides electrocution hazard wood stoves and radio show mitten racks lol. It did fuel a fascination for electronics, though, so by the time I was seven I was an avid reader of popular electronics magazine. Forrest Mims. What a treasure of an engineer. https://en.wikipedia.org/wiki/Forrest_Mims https://en.wikipedia.org/wiki/Forrest_Mims
- lxgr 2y ago> [...] bush relay messages for remote listeners outside of telephone reach [...] That sounds fascinating! What types of messages were these usually?
- K0balt 2y agoSo and so is going to some place up river, will bring something, so and so died, the funeral is….somebody came is in town until the 29th, etc.
- andrecarini 2y agoGreat story, thanks for sharing!
- Semaphor 2y ago> You’d hear a noise right before your phone started to ring! Hah, haven’t thought about that in a long time. That’s the anecdote that feels unbelievable if I hadn’t frequently experienced it myself.
- TeMPOraL 2y agoThat was an incidental but very useful feature!
- ltrls23 2y agoIt was used in some nice electronic music! Dual Band – GSM (1998): https://www.youtube.com/watch?v=ntKOJdht3t8 https://www.youtube.com/watch?v=ntKOJdht3t8 Mav – HGP (2005): https://www.youtube.com/watch?v=ZacenNeu4fw https://www.youtube.com/watch?v=ZacenNeu4fw Tatarola – Who Is Calling (2007): https://www.youtube.com/watch?v=hTOyaG7VYKw https://www.youtube.com/watch?v=hTOyaG7VYKw
- myself248 2y agoSometimes that was pretty useful though; you could infer a lot about the system's state by listening to the faint hints of bus activity!
- Asooka 2y agoBack in the CRT days my speakers would make noise whenever I scrolled a website, lol.
