JNells Posted February 9, 2014 Report Posted February 9, 2014 Does/has Moore's law (law that states computing circuitry and processing power will effectively double every 18 months) apply in the car audio world as well? Specifically with amplifiers. Malibu Build Log
Neckbeard Posted February 9, 2014 Report Posted February 9, 2014 Hmm.... Not really sure, But i know back in the day, it was like 1$/1w for just the amp. Now days it's cheaper, but this probably doesn't mean shit to your question lol Build log, Super slow!!: http://www.stevemeadedesigns.com/board/topic/168096-slow-neckbeards-1970-opel-gt/
JNells Posted February 9, 2014 Author Report Posted February 9, 2014 Yea I mean I know amps and everything have come a long way over the years even in the last couple (cheaper/smaller/more efficient etc). Just curious if computing and amplifier processing power evolves at a similar rate. And I'm guessing that analog/digital plays a role in some way... Please feel free to chime in, open for discussion.

Krakin Posted February 9, 2014 Report Posted February 9, 2014 It's not exactly as black and white in audio with the amplifiers. There are plenty of big sound quality guys that still use amplifiers that are older than I am. As for the cost/performance you can now get amplifiers that are insanely cheaper than they used to be. Krakin's Home Dipole Project http://www.stevemeadedesigns.com/board/topic/186153-krakins-dipole-project-new-reciever-in-rockford-science/#entry2772370 Krakin, are you some sort of mad scientist? I would have replied earlier, but I was measuring the output of my amp with a yardstick . . . What you hear is not the air pressure variation in itself but what has drawn your attention in the two streams of superimposed air pressure variations at your eardrums An acoustic event has dimensions of Time, Tone, Loudness and Space Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears, thus no formula can achieve a definite effect for every listener.
SnowDrifter Posted February 9, 2014 Report Posted February 9, 2014 Moore's law applies more to computing hardware (processors -- transistors. Things with logic) Amplifiers are more like sophisticated transformers than they are processors ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444
JNells Posted February 9, 2014 Author Report Posted February 9, 2014 Moore's law applies more to computing hardware (processors -- transistors. Things with logic) Amplifiers are more like sophisticated transformers than they are processors That makes sense. So probably applies in signal processing if at all then? (RF 3.sixty.3 for example). When will we make the leap into "smart" amplifiers? Lol Malibu Build Log
Wicks Posted February 9, 2014 Report Posted February 9, 2014 Moore's Law applies to the number of transistors you can fit on a silicon die. Therefore it relates more to advanced microprocessors (digital) then amplifier circuits (analog). So unless amplifiers require a massive amount of computing power then I doubt it. The biggest advancement with amplifiers comes in different circuit architectures, as Class D amps did vs Class A/B. RFs "Boosted Rail" technology is an example.

JNells Posted February 10, 2014 Author Report Posted February 10, 2014 Yea that's what I was thinking, but not being an expert I figured id ask you guys. But that's what I was kind of getting at, the advancement/evolution of components in car audio. What will be the net big revolution? Malibu Build Log
P4killer_ Posted February 10, 2014 Report Posted February 10, 2014 Theres a limit though. I think current scales are at 22nm? At that point regular engineering doesnt even apply. Were talking atomic particles and Its about physics and micro idk w.e than it is like ohms law. I doubt if amps relatively speaking would make it that far. Itd be crazy though. Theres chips with like ya know 4 op amps on each chip. Would coooould be refered to as amplifiers, but itd be crazy to be like yea ive got a quad sundown 3 k on a 8 pin package.. Even if it were like a 60 lb chip with like 1 inch dia legs. . Thatd be crazy.
