A synthesizer (spelling var. synthesiser) is an electronic musical instrument designed to produce artificially generated sound, using techniques such as additive, subtractive, FM, physical modelling synthesis, or phase distortion.

Synthesizers create sounds through direct manipulation of electrical currents (as in analog synthesizers), mathematical manipulation of discrete values using computers (as in software synthesizers), or by a combination of both methods. In the final stage of the synthesizer, electrical currents are used to cause vibrations in the diaphragms of loudspeakers, headphones, etc. This synthesized sound is contrasted with recording of natural sound, where the mechanical energy of a sound wave is transformed into a signal which will then be converted back to mechanical energy on playback (though sampling significantly blurs this distinction).

Latest news on synthesizer
Today on Boing Boing Gadgets
Today on Boing Boing Gadgets we saw this pretty and entirely pedestrian HP Calculator; the Konami code for Google Reader; a industrial shredder eat an Asteroids cabinet; GPS-maker TomTom's intention to make iPhone software; the mystery of Macbook Air's optical illusion beveled design (and other nice laptop design tricks); a way to project trippy Hello Kitties all over your ceiling; a fancy shisha maintenance kit that looks like a espresso maker; fancy Italian asymmetric sunglasses; a whole bunch of alarm clocks; beautiful Pac-Man-inspired art; and a way to store your shoes that has a better name than execution. We also glanced at Mac OS X 10.6 Snow Leopard; saw not one but two different all-in-one desktop PCs; discovered a way to cheat at Guitar Hero with a machine; played Star Wars 'Imperial March' on a floppy drive; shuddered at a phone shaped like a giant butterfly; saw that Bob Moog's company has a guitar with infinite sustain; applauded a outdoor router from D-Link used in a Native American wind generation system; saw a vending machine that crushes fine china (yup, it's art!); and found another DIY project we'll never make: a bank of Commodore 64 SIDs made into a big synthesizer. But the best thing we found all day? (At least in my opinion?) The Little Red Riding Hood?s Zombie BBQ game for the Nintendo DS....
Moog electric guitar
The new Moog Guitar Paul Vo Edition is made by the famed synthesizer company but is not a guitar synth or MIDI controller. However, the electric geetar is capable of "infinite sustain" that impressed the hell out of Lou Reed. Listening Post has details along with a promotional video featuring Reed and other guitar heroes. Link...
