Hands-On WebAssembly for C++ Programmers - Playing Simple Sounds in SDL

The video tutorial introduces DDL Audio, a library included in SDL for low-level audio control. It demonstrates how to set up SDL audio to play simple tones and wave files. The tutorial walks through a code example that plays beeps using SDL audio, explaining the setup of header libraries, the global beeper object, and the audio callback function. It covers the process of generating audio samples and compiling the code to run in a web browser. The video concludes by hinting at future tutorials on playing wave files and integrating sounds into a pong game.
