EE 123 Lab 3: Sampling & Compression — Audio + Image

This lab connects sampling, resampling, and quantization with transform compression (a JPEG-like pipeline).

Prerequisites

• Python 3.x

Environment Setup

Install the required packages listed in requirements.txt:

pip install -r requirements.txt

Lab Structure

File	Description
lab3-sampling-compression.ipynb	Main lab notebook (Part 0–5)
assets/	Audio assets (orchestra clip, 44.1 kHz)

Getting Started

1. Open lab3-sampling-compression.ipynb and work through Parts 0–5
2. Fill in all # TODO sections and answer the questions

Notes

• This lab is a take-home assignment.
• Use IPython.display.Audio to listen to audio clips directly in the notebook
• For the JPEG-like compressor, do not call Pillow's JPEG encoder except in the one task where you compare against it
