In this talk, Attila Haraszti discusses the integration of Rust for web audio applications, emphasizing the complexities and challenges of using Rust in a browser environment compared to JavaScript. He highlights the importance of audio processing precision and the need for predictable performance, particularly in real-time audio applications, while introducing his project, Songling, an audio workstation built for the web. Key technologies mentioned include WebAssembly, the Web Audio API, and various Rust crates for audio processing, with practical takeaways on optimizing bundle sizes and managing memory effectively in a web context.
