Could you build this?
No A multitrack in-browser DAW with waveform rendering, audio effects, editing buffers, and real-time playback requires specialized digital signal processing (DSP) and Web Audio API architecture.
What it would actually take: The engine relies on Web Audio API, AudioWorklets, and WebAssembly for DSP routines (filtering, resampling, timeline mixing, dynamic compression) coupled with custom Canvas/WebGL rendering for high-frame-rate waveform visualizers. The hard parts are low-latency multitrack synchronization, non-destructive editing history with large audio buffers, and memory management in the browser. Developing this requires deep expertise in digital audio processing and browser threading models.
