Is there a program that can take a sound or a whole song and break it up into every individual frequency it contains and show the envelopes of them all as sine waves?

someone posted a preview of something that i think did what you're describing a few months ago. it looked really slick though I don't know the name of it. i think it had some options for manipulating sound as well.

What the fuck? No fucking way could something like this exist.

Seeing as you can make any fucking sound ever possible (seriously) with additive synthesis, a program that is basically reverse additive synthesis is not that far-fetched. Also, simple versions of it already exist, like having sytrus, alchemy, or other synths turn a sample into the sine wave harmonics that make it up. But they don't even do it completely accurate because it would take alot more sine waves than they have the cpu available for.

@Fauster Why not? I could see this being made fairly easily.

Well, not exactly what you described I guess (mostly the specific sine waves?), but you might want to look into the interesting R-Mix: http://www.rolandus.com/products/produc ... uctId=1176

I think melodyne comes sort of close

It would require an infinite amount of sine waves. There's no way that software exists anywhere.

Edit: "Seeing as you can make any fucking sound ever possible (seriously) with additive synthesis" is a gross overstatement if you're talking about current additive synthesis software/hardware.

May I ask how? I might be missing something.



I've seen this posted around here a few times. Take the time to read it. It's worth it.

no just roughly between 20 and 40,000 hrtz.

isnt that what a spectrum view is in a wave editor

No. An infinite amount. There are frequencies between 30 hz and 31hz, for example. Hertz is just the measurement of frequency, standing for one cycle per second. Waves exist at say... 40.51 hz. For example, middle c is 261.625565 Hertz.

Edit: Why did you choose 40k hz? Human hearing ends around 20k and the nearest sample rate that can reproduce 40k is 96...

It would only need to include the frequencies that are used. Just because 30.58536942743 Hz is possible doesn't mean it's used in the tune.

Ok maybe not infinite, but way too immense for a program like this. I'd imagine an insane amount of frequencies would be used in some amount over the course of a song.

Indeed. Which is why I don't think such an application would be efficient...besides, I don't see it being useful any more than IL Wavecandy's Spectrum Analyzer.

i know it's not EXACTLY what arte was talking about. BUT there was a thread a few months back about some sort of new 3d-ish spectrum analyzer/manipulator. It had a cool promo video and I think the skin was green. It was like a spectral analyzer that took up your whole screen. Anyone???

I was thinking about this last night and Fauster's point about infinite waves. While in a finite amount of time, there would be a finite amount of frequencies, think about if you had a simple sine sub bass doing a pitch slide. How many frequencies would be counted within the range of sliding from say 40Hz to 50Hz?
Also, I understand that it would be very difficult to analyze 1khZ and up, especially with a lot of atonal noisy stuff like high hats, high ends of snares, kick, other cymbals, etc. Normal spectral analyzers have limited resolution in the high register.
I also realize that it would be impractical to try to analyze the higher stuff because there's just so much information but how difficult or how long would this take a computer to do?

Theres a freeware I found like that and thought that minus sine waves is pretty close to what he is saying.

Not necessarily. There are an infinite amount of numbers between 1 and 2. 1.1, 1.11, 1.111, etc...
The same can can be said about frequencies. Theoretically, if all the frequencies are present at the same time, then there could be an infinite amount of frequencies present in a very short period of time, and still only be between 40 and 50 hz.

Now, this most likely is never going to happen. You're usually going to have a finite amount of sine waves comprising your song, but there is ,most likely, going to be an incredible amount. Way too many to have a program analyze and display efficiently.

http://www.klingbeil.com/spear/ I think this is as close as you're going to get atm, free as well.

but why would you need to see the infinite amount of space between 2 whole numbers. yes 1.11167465 is a number between 1 and . but we can also round it to 1.1
