vinyl is better than CD because its capable of reproducing so much more sound than was even originally recorded in the studio

when you get an amiga you have to do a cover of Paranoimia, i think its the law

my favorite part of The Visitors by ABBA is how the intro is interrupted by Benny Andersson switching on his Game Boy

@jk Or in tune with the rest of the chip. I believe I read somewhere that it's about a quarter of a semitone out. Almost good enough for just thirds. If I could remember if it's sharp or flat...

@jk harmonics on the mains are a drawback of todays technology as well as the use of any motors etc. Any metal cased switchmode PSU (like your desktop PC) has filter circuit which supposedly dumps all the EMI to "earth" but on many networks this earth is combined in the neutral cable.at the distribution points, plus the internal wiring in buildings now radiates all this interference (increasingly an annoyance for radio monitoring, the signals even reach into VHF bands nowadays)

@jk destroyed a portable hard drive that way once!

@MightyPork @jk I've seen better sine waves from the DPCM channel on a 2A03...

@jk fuschia

@jk and also here are spectrograms of the noise produced by a laptop charger, regrettably without a scale https://dev.glitch.social/media/cpYxjZ5rLFgaSvfK4cI https://dev.glitch.social/media/582NJ3lc5ZXnoxYwWXM

@jk I've actually done this for my thesis and can affirm that there's anything but sine waves going on - those are current waveforms with a motor, messing it up for anything nearby

@jk Ugh, looking at the outputs on scope is horrendous.
