# Kymatio Workshop 2022: Scattering1D Tutorial
[Google Colab](https://colab.research.google.com/drive/1J1nag-XlanlfbeH8hSshsqPMaelSnDkf#scrollTo=2IukvoLHcLC9)
In this tutorial we will work through examples of `Scattering1D` (Time Scattering) in Kymatio.
The intention is to gain an intuition of the physical properties of modulated signals and their scattering transform.
### Part I
* understanding the scattering filterbank construction parameters (`J`, `Q`, `averaging`, `order`, `paths`)
* plotting the wavelet filterbank
* visualizing the response to modulated sounds that appear in music and speech
- amplitude modulation (tremolo)
- frequency modulation (vibrato)
- attacks (note onset)
- amplitude modulation interference
- musical instrument playing techniques
### Part II
* Generate a dataset of synthetic signals with varying spectral shape and interference patterns
* Unsupervised manifold embedding of the nearest neighbour graph (Isomap) of the dataset under Scattering1D
