A deep technical walkthrough of building a multi-dimensional wavetable synthesizer using Rust compiled to WebAssembly, integrated with the Web Audio API via AudioWorkletProcessor. Covers wavetable theory, multi-dimensional interpolation, Rust data structures for DSP, bypassing wasm-bindgen for AudioWorklet compatibility, Wasm module size optimization with wasm-opt and wasm-strip, debugging strategies without wasm-bindgen, generating basic waveforms (sine, triangle, square, sawtooth), and the full JavaScript/Rust interop pipeline for real-time audio processing in the browser.
