Analog Synthesis and Subtractive Synthesis
Is it the same thing? |

no, you can have analog additive, but generally speaking analog is subtractive.
Subtractive means you start with one sound, and you take away from it. yuou can make an analog synthesizer that is additive |

Analogue synthesis means synthesis using analogue electronic components in which the waveforms and control signals are represented as continuous electrical signals, and can therefore take any value between the maximum and minimum allowed in the circuit.
This is as opposed to digital synthesis which is basically synthesis using quantised (digital) representations of waveforms and control signals. Digital synthesis is an abstraction of analogue synthesis, and although it offers many advantages it must be remembered that in general digital representations of waveforms are only an approximation to the analogue signal.
Both digital and analogue synthesis can be performed in many ways, the most common of which is subtractive synthesis. Digital synthsis offers the opportunity to develop synthesis methods that would be impossible (or prohibitively difficult) using analogue techniques, eg. granular synthesis, resynthesis, sampling.

"Digital synthesis is an abstraction of analogue synthesis"
don't want to whine too much  but i think this only goes for Virtual Analog type of digitaal synths.,
digital synthesis can be anythin as long as it results in sound., |

Analog synthesis - made by electronic synths but not digital
Digital synthesis - any type of synthesis with 1's and 0's.
Substractive synthesis - you start out with a waveform and take out from it using stuff like filters. 99% of analog synths are like that and the majority of digital synths as well.

Additive synthesis is (was???) too dificult to implement.
Let's say that you want to emulate the sound of string. So you basically sample the sound of a string and analyze its' spectral content.
You find out let's say 566 strong signals in various frequencies. And then you decide to implement it with additive synthesis. Which is basically taking 566 oscillators that are set to the frequencies which you found in the analyzing part.
That's what ppl were trying to do in the first days. But as you figured out already it's too pricey (not to mention physically difficult) to find 566 oscillators and tune them precisely to the values you found. And offcourse the more elements you'll find and find of the original sound that you try to immitate the more true to the original the imitated sound will appear.
But then there are synthesizing methods that are easier than this one. The subtractive offcourse, the sampling method and the FM synthesizing.
Everyone in the world is doing something without me |

doggo, not to nitpick, but isn't ALL digital syntehsis inherently a representation of something analog? sampling is simply a representation, so that takes sample+synthesis out, wavetable, and just about anything else. what doesn't use samples for oscillators that doesn't emulate(VA, physical modelling)? |

"doggo, not to nitpick, but isn't ALL digital syntehsis inherently a representation of something analog?"
of course in the end it's ment to represent sound but digital synthesis does not neccesary representing analogue cirquits as used in analogue synthesis.,

yes but the world around us analog. therefore anything is merely an emulation of the world, no? |

mp3 uses a form of additive synthesis to replay your precious tunes

well, actually quantum theory states that the universe is in fact quantized so analog as most ppl see does not exist ...
so what is emulating what ?
but it's just a theory.,
back to the discussion,
i was only commenting on the fact that most forms of digital synthesis are NOT an abstraction of analog synthesis.,.,
it's just that the sound of analogs is so popular and that most synth manufacturers try to achive this sound in their digital synths.,
but with digital you can go into so many other ways than doing what analog synths do.,
like yamaha-style fm.,
or additive synthesis.,
or wavetable synthesis.,
or neural synthesis!
the list goes on .,.,

wavetable!, wavetable just reads samples, additive jsut utilizes samples of sinewaves, and neural synthesis(which doesn't really exist, neurons recognize the patterns in sound, and then apply that to an algorithm, then the algorithm isp layed back much like pcm actually)...is emulative...they're all emulative, until u can give me an example of non emulative synthesis it is all lies! |
