Okay, so now we see the result and

we clearly see that in the transitions there are gaps and

this is because, in the transitions, the fundamental is not very clear.

We are in a kind of attack, noisy attack.

So it has lost a little bit of the transitions, and if we listen to that,

in fact, we're going to listen to these gaps.

Okay, so there are gaps in the transitions because that's where the areas that it

didn't find the fundamental and therefore it didn't find any harmonics.

And that's basically all I wanted to say.

So let's go back to the slides and well,

we have used the SMS tools GUI in order

to analyze this cello fragment.

And we have used the short time Fourier transform, the sinusoidal model,

and now the harmony model, to see this phrase and to analyze the harmonics.

And we can see that by tweaking the parameters, we can get quite

a bit of difference in the way that these harmonics are analyzed.

So, that's all and this is all for the demo classes of this harmonic model week.

So hopefully this has given you a view of

how the harmonic model can actually be used in practice.

And still, it's not ideal.

There is some parts of the sound,

especially like in this sound that we just heard in the attacks,

that we lose a little bit of the sound that is present there.

So the next week, we will extend the idea of the sinusoidal and

harmonic model to include that aspect,

to include what we will call the residual or the stochastic component.

Hopefully, that will allow us to generalize our models and

to be able to handle many more types of sound.

So I will see you in the next class.

Thank you very much.
