The type cast as Float32Array<ArrayBuffer> appears unnecessary. The Web Audio API's copyToChannel method accepts Float32Array directly. This pattern is not used elsewhere in the codebase - for example, src/utils/audioStream.ts uses getChannelData().set() without type casts (line 422), and src/utils/dsp.ts uses direct array access (lines 134-135). Consider removing the type cast to simplify the code and align with existing patterns.

Summary
Completes Multi-VFO integration by connecting the existing DSP pipeline to the IQ sample flow. Users can now create multiple VFOs within the visible bandwidth and simultaneously monitor different signals (e.g., air traffic on 118.1 MHz + weather on 162.55 MHz within a 20 MHz capture).
Implements the
useMultiVfoProcessorhook to manage the MultiVfoProcessor lifecycle, routes IQ samples from SDR devices through the multi-VFO processor for demodulation and audio playback, and adds optimized Web Audio API utilities for audio context management, buffer playback, and stream mixing.Addresses multiple rounds of PR review feedback including:
vfosto effect dependency array to ensure proper re-runs when VFOs are added, removed, or updated in the store (fixed issue where effect only ran once after mount)vfoModesref to track mode per VFO ID, ensuring demodulators are recreated when a VFO's mode changes (e.g., "wbfm" → "nbfm")addedVfoIdstracking set when processor is recreated to ensure VFOs are properly re-added to new processor instances?? 0) consistently throughout audio processing code to comply with TypeScript'snoUncheckedIndexedAccess: trueconfiguration (tsconfig.json line 110), which adds| undefinedto all indexed access operations for enhanced type safetyas Float32Array<ArrayBuffer>) required for Web Audio API compatibility with TypeScript's strict type systemNote on Type Casts: The
