Speech & Audio

The other half of human communication. Hear, understand, speak.

Start this phase on GitHub

Prerequisites: Phase 1 vectors, matrices, and probability. The first demo uses only the Python standard library.

First lesson: Audio Fundamentals

Run this command from the repository root:

python3 phases/06-speech-and-audio/01-audio-fundamentals/code/main.py

Keep the command, exit code, detected frequency peaks, alias frequency, and an explanation of why a low-pass filter must run before downsampling.

Next action: Change the source tone and predict its aliased frequency, then continue to Spectrograms and Mel Features.
