what does 'modular' mean? nord modular, moog modular, numerous oscillators on board, what does it all mean? |
||||||||
|
|
|||||||||
| |||||||||
|
|
Some synths are self-contained. Meaning they have no spaces for expansion A modular synth basically means it can be plugged in with other objects or "modules", parts of it take out and put back in, easily. Like it was made to be expanded, ect. That's not a great definition, but hopefully you get the picture |
||||||||
|
|
|||||||||
| |||||||||
|
|
thanks! i see it much clearer now but what does the number of oscillators affect? |
||||||||
|
|
|||||||||
| |||||||||
|
|
more oscillators = more IDM power. You can go further up your ring if you can fanny around for days getting a noise that goes just goes 'peow'. |
||||||||
|
|
|||||||||
| |||||||||
|
|
An oscillator basically gives you a wave. This is normally one of any "standard" waves, like sine, square, triangle, etc. When you add two waves together, you get a new waves. Each oscillator gives you a new wave to work with. If you add enough sine waves together you can get ANY sound. |

|
I like this thread. learn something new everyday! |
||||||||
|
|
|||||||||
| |||||||||
|
|
but how do you get any sound adding more waves if the waveforms are limited? like, sqr, sin, tri, etc.? are there any additional properties that can make every oscillator's wave unique? |
||||||||
|
|
|||||||||
| |||||||||
|
|
yeah, it's like Sesame Street Goes IDM |
||||||||
|
|
|||||||||
| |||||||||
|
|
"if you add enough sine waves you can get any sound" in theory... but not really in practice.. |
||||||||
|
|
|||||||||
| |||||||||
|
|
:D haha I personally hope the trend of asking intelligent questions and getting responses continues because this could be quite a useful little thread! I wish i could think of something off hand. *ponders |
||||||||

It's called subtractive synthesis. You start off with the osc than add filters, modulators and envelopes to subtract from the original waveform. "Add to subtract"...lol |
||||||||
|
|
|||||||||
| |||||||||
|
|
By shifting pitch of the wave forms, you get a wave that has a higher frequencies (more cycles per second, more Hz, faster, however you want to visualize it) By shifting the amplitude you get a wave that has higher peaks By fussing with these two qualities and adding the waves together you can get neat sounds Effects are basically shortcuts for wave addition, they give you a sound without the work. Go experiment my son, twiddle thy knobs, flang and verb thy noise, for it is the only way thy shall experience the glory of IDM |
||||||||
|
|
|||||||||
| |||||||||
|
|
Yup, when using Fourier analysis a sound is described with just sine waves. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Well yeah Zeus... I'm giving him theory, he needs to experiment to figure out what everything does. Be positive! |

How does a ring modulator work? What is LA synthesis and how does FM synthesis work? |
||||||||
|
|
|||||||||
| |||||||||
|
|
I'm quite experienced in the meaning of making music and applying effects, but i got a bit confused imagining those simple waveforms colliding to give birth to a monstrous squeaky string sound... like if you realized that Sagrada Familia cathedral is actually made from kids' ABC blocks |
||||||||
|
|
|||||||||
| |||||||||
|
|
Gotcha... yes, it's possible, yes it requires a LOT of waves to do it, but more possible now than before, the original subtractive synthesis was done with 4 waves if I remember right Ring modulator takes two sounds and outputs an addition of the two waves and a subtraction of the two waves. FM synthesis, frequency modulation, is complex, I'd recommend checking a web site, I'll look one up later tonight for ya, I remember someplace with some good info. Unless somebody else has a good explaination |
||||||||
|
|
|||||||||
| |||||||||
|
|
cheers! |

FM: Instead of using oscillators with different wave forms it just uses sine waves. Check out the FM7 plugin if you want a good visual representation. Each of the sine waves are modulated separated and then added or subtracted together |

what's granular synthesis? |
||||||||
|
|
|||||||||
| |||||||||
|
|
so... whos gonna try and explain grainular synthesis... ;) :D |
||||||||
|
|
|||||||||
| |||||||||
|
|
haha i wrote that before seeing that, guest :) |
||||||||
|
|
|||||||||

LA Synth... didn't see that Linear Arithmetic synthesis: All the information is in mathematical formulas, not converted to sound until the end. You have the effect of hearing things you're used to, but it's all mathematical. The traditional wave forms are still there but just as math functions. The one I used had a lot of built in samples you could fool with... I think it converted them to digital information and processed that before converting to sound |
||||||||
|
|
|||||||||
| |||||||||
|
|
Is it a sample chopped up into tiny parts, then each part repeated and/or crossfaded? Fuck knows, I'm only 12. |
||||||||
|
|
|||||||||
| |||||||||
|
|
thanks! I never knew what that meant. |
||||||||
|
|
|||||||||
| |||||||||

Granular Synthesis: The sound is broken up into "grains" and then processed. Each grain is a small portion of the sound, like taking cuts of a sample, it takes extremely small cuts of each sample and processes based on that. This works because the ear can only process sounds so quickly (like 20ms or so) so if you break the sound up to parts that small, you can process them as a stream of grains I'm gonna look up more on LA and Granular tonight too... I'm a little flakey on the details beyond that |
||||||||
|
|
|||||||||
| |||||||||
|
|
Yeah, exactly Jivver... they crossfade them just a little bit when they put them back together |
||||||||
|
|
|||||||||
| |||||||||
|

I made a totally awesome sample from that piece in Isopropophlex when the child sings (also appearing in Come To Daddy video) using granular synthesis. I love it! I can send it if anyone wants, it's TOTALLY great, like, a dark ambient masterpiece in 3 secs :) |

http://music.calarts.edu/~eric/gs.html http://homepages.kcbbs.gen.nz/gordon/granular.html These links contain interesting reading material pertaining to grainular synthesis. |
||||||||
|
|
|||||||||
| |||||||||
|
|
so if you used grainular synthesis... why did you ask what it is? |
||||||||
|
|
|||||||||
| |||||||||
|
|
Hehe... it's one thing to USE something, totally another to understand it, ya know? Hell, I don't know what the heck half of the things I use actually are doing, I'm just scratching the surface and getting what I want once in a while |

To quote virgin "I personally hope the trend of asking intelligent questions and getting responses continues because this could be quite a useful little thread! I wish i could think of something off hand. " guest kinda took the inititive to ask some questions that others might find important and/or useful at a later time. |
||||||||
|
|
|||||||||
| |||||||||
|
|
Feel free to ask, I love sharing what I know, and gives me incentive to go find out stuff about what I don't know And as a token of appreciation could always feed my ego and go review the track I have up on the thread down |
||||||||
|
|
|||||||||
| |||||||||
|
|
well, i wanted to know if the thing i was using was using granular synthesis and that's what it's called |
||||||||
|
|
|||||||||
| |||||||||
|
|
i know exactly what you mean im studying csound right now, in college... and i have to know how all types of synthesis works... because csound is text based... so i cant just twiddle knobs and find a sound... i have to know what exactly I want, and how to get it. a challange... but very rewarding :-D |
||||||||
|
|
|||||||||
| |||||||||
|
|
I'm looking into getting into that soon Zeus, programming sound... *drool*... far beyond me right now, I'm still trudging around LISP You know of any good sites for a PC version of csound or any other algorithmic tools? I've found a handful, but they're all pretty bad |

heres a good one - sample rates - now - what is the information contained and restricted by/in samples rates - like - what makes an 8bit sample rate differant from 16bit? |
||||||||
|
|
|||||||||
| |||||||||
|
|
*goes to check it out* |
||||||||
|
|
|||||||||
| |||||||||

A CD, with 16 bit samples, means each portion of sound (14400 per second) are represented by a 16 bit number, or 65,536 possible values, 2 to the 16th. With an 8 bit sample, each is represented by an 8 bit number or 256 values. With more samples, you get more values, which means more accurate sound representation. |
||||||||
|
|
|||||||||
| |||||||||
|
|
it's like resoloution in digital images I think...16 bit has twice the amount of 'snapshots' of a sound than 8 bit. |
||||||||
|
|
|||||||||
| |||||||||
|
|
That's a common misconception Jivver... 16 bit is the SQUARE of 8 bit... much better quality |
||||||||
|
|
|||||||||
| |||||||||
|
|
so that's loads more informaton! that's amazing really.. |
||||||||
|
|
|||||||||
| |||||||||
|
|
www.csounds.com is the official site. any thing and everything you want to know about it is there |
||||||||
|
|
|||||||||
| |||||||||
|
|
i see - so its basically the encryption rate - and i figured that 16 is the square of 8 :P im learning more and more about computer theory as i learn sound theory |
||||||||
|
|
|||||||||
| |||||||||
|
|
Yeah, 2^16 is (2^8)^2 No more math, my brain hurts |
||||||||
|
|
|||||||||
| |||||||||
|
|
Yuk. Math hurts me. |
||||||||
|
|
|||||||||

sample rate is the horizontal resolution of a sound, how many points (samples) per second are used to represent it bit depth is the vertical resolution, number of values a sample can take, like, how much your sine wave will look like a staircase. if you make a 3-bit wave, you'll see one. 1-bit sine is like _-_-_- only two vertical states! and if i double its sample rate then we get __--__--__-- twice as much points used to encode a sound of the same length |
||||||||
|
|
|||||||||
| |||||||||
|
|
I'll bump this as maybe others have questions that i havent thought about asking and we could all learn from each other! :) |
||||||||
|
|
|||||||||
| |||||||||
|
|
What you're describing sounds more like sample rate. My understanding was that bit depth has more to do with the volume ramping of digital audio - with more possible values for each sample there's more headroom and more resolution for quieter sounds and differentiation between volume levels. |
||||||||
|
|
|||||||||

Actually, ring modulation multiplies two signals. I think you got confused because of what happens in the frequency domain when you multiply two sine waves - if you multiply two sine waves at frequencies f1 and f2, you get the same result as if you add two sine waves at frequencies f1-f2 and f1+f2 (they "reflect" if they reach zero or the nyquist frequency; I'm leaving out phase issues so as not to add to the confusion). That equivalence is also why when you add two sine waves of very close frequencies you get what's usually referred to as "beating", i.e. the result gets louder and quieter and louder and quieter again, like a single sine wave multiplied with another of a very low frequency. I don't know where you got these descriptions, but the one for FM is also wrong - what it is is taking one wave and making it change the frequency of another, like a very fast vibrato if you will. Most good FM synths aren't limited to sine waves either. |
