Lab 6 Check

Run the audio tests before judging the result by ear. The tests can verify byte counts, buffer bounds, and deterministic sample output even when your local machine or browser would play the sound differently.

Discussion Prompts

When reviewing the lab, discuss what changes if you generate sine waves instead of square waves, how a tracker could represent notes, tempo, and instruments, and why audio APIs often use ring buffers.
