So, yeah, every single car voice proceeds by JavaScript and actually Web or your stuff.

So before I go and deep how to make it I just introduced myself.

I'm working for a company called Weapon Systems.

I'm co organized in angle of roads, left meet ups here.

And yeah, I have hold me to play a guesser.

You can for months Visa This my candle and my personal work.

Actually, weapon audio is you need directed graph that contain our dear nodes.

So what is sexually union directed graph?

It's a bunch of dots connected with some directed arrows.

Basically, we have some input or source off our sound.

And be careful, I'll put between source and output.

We have some knows that's going to at some effects process audio, our rodeo, analyze it, whatever.

And we have the same for neater stack the kalfan input our instrument and we have output speakers or some stack of speakers on between those.

We have some effects amplifiers, cabinets, distortions over drives, all this stuff.

So, first of all, how we can connect our gifts are to rep order.

So we create in our order contacts and is a man point where the operating out d'oh graph them really question the media using Navigator media devices.

And if we want to use only order, real question order.

It's easy, Yeah, but it won't be that easy.

So wait for a moment to use an instrument as a stream.

True, getting user maeda, but two clean up our sound.

We need to use some constraints because by default browsers applying echo cancellation, noise suspension out a gain control and some Latin cito our input.

We need to use those constrains enters the last step.

There's the stream that goes through our input throughout your car and then reconnected.

Our source risked context destinations at our speakers or another destinations that we can choose in our system.

So when we can exception, we want to control the volume, how out it is how to do so.

We have a special loads gain note, and we can imagine our sound wave as a sign Empty fi divided by two or multiply by a CZ 05 We will get the smaller signed wife, and the amplitude off this sine wave actually means our volume.

So to reduce sound, we need to divide by two.

To increase south, we need to multiply, but some number so house looks and called decorating our gain note using constructor or factory matter on context, and after that we can apply.

One is it's normal, and if it tires and one, it will be louder than originally input.

We need to deal with these graph, so we kept our source.

Then we connected to gain no to control volume and connect a gain to this nation.

How it's looks like what's does that not That's not reasonable.

So, yeah, I have an application, and I have connected source.

They have a volume control so I can make it Not the cloud.

So yeah, it was the basic stuff, actually.

Is this malady I wrote myself some time ago.

So Okay, just effect I want to show is decision.

So you can't imagine an Iraq music without distortion sound And basically, what is distortion?

It's a group off effects that shaping our way and put sound with some function.

Distortion and Foods and all of them Still cold foods.

I want to Stella story How it was invented.

The amplifiers wasn't that good as they are now, and they were broken sometime.

So who if speaker was broken it SATs to produce deserted found.

So some people started to destroy, destroy their amplifiers themselves to get this sound before it was done by some transitions and so on.

They don't destroy speakers so called look like again we carefully inputs.

That's actually a say sine wave, yes, and we apply some function to it to make it more square.

So this more square sound gives out our sound to be deserted.

For example, we can apply that functions that is here.

But what's the difference between overdrive, distortion and foods?

So the differences house moves is that curve over his wife is usually some soon lamp base, so it's more smooth curve distortions kept some more harder.

One and food's basically sounds like something additional.

It's almost flat sine wave, so toe shape out where input in way we want it we can use with shaper.

We can creating and apply a cure and Curve is a floating certitude beach airy.

Continue numbers that's we will be applied by audio and receive our sound.

So we creating some Ari the loops reads and apply on our function.

Then that's function will be reviewed re based on our input to achieves that deserted sound.

Also, we want to control, tone or even create some localization for our effect to create simple tone control.

Type off Lopa Slow pass because future means that everything's the ever since that goes down to some particular frequency will be cut off from our sound.

So controlling uses a frequency of this filter from lower 352 highest.

If I was, sounds will be higher or lower.
