Could you build this?

Partial The web UI and ONNX Runtime Web wrapper are straightforward to vibe-code, but executing heavy audio source separation locally in the browser requires complex audio DSP and memory optimization.

What it would actually take: The stack requires ONNX Runtime Web with WebGPU/WASM acceleration alongside a client-side audio DSP pipeline implemented via Web Audio API or AudioWorklets. The hardest challenges are replicating torchaudio's exact short-time Fourier transform (STFT) and inverse STFT math in JavaScript/WASM, chunking audio with overlap-add without phase artifacts, and preventing browser tab crashes from high memory consumption.
