The steps that I followed for this mini-project were as follows:
I first gathered and learnt about the resources I would be needing by searching them through the internet.
It was not a one day work though the project seems small. I ran into multiple challenges which I will be mentioning below.
I first recorded the audio of breathing in mask.
Then using IPython I imported it in my jupyter notebook.
To do the analysis of the audio I used Librosa package mainly used for Sound analysis.
I learnt about the low-pass filter to filter high frequencies and coded one(I faced a lot of issues here :) ).
Then using Matplotlib and Librosa's display feature I plotted the waveform and spectogram of Original and Filtered audio.
So basically I had pre-requisite knowledge in Machine learning, but I learnt a lot of things
Like I was aware of Matplotlib but wasnt aware of Librosa's waveform feature.
I also learnt how to make filters in python(I only learnt about them in theory thanks to an Electrical Engineering course)
Also Quarto is just something I didnt know and glad through this project I learnt about it, because it really does wonders. Definetly going to use in my future projects.
There were a lot of challenges I ran into:
Firstly my packages were installed but were showing "module not found", fixed that with a lot of frustration.
I also faced issues with Quarto since I was completely new to it.
And a lot of errors in making the low-pass filter.
My github was also not committing changes smoothly, it was continously showing errors.
