Traditional Digital Signal Processing (DSP) provides deterministic, instantaneous audio editing right inside your web browser.

The browser's native Web Audio API decodes formats like M4A or MP3 into floating-point audio sample buffers.

The algorithm evaluates energy blocks via Root Mean Square (RMS) equations to pinpoint sub-threshold silence.

Active segments are stitched together with tiny crossfade curves, eliminating clicks or popping artifacts.
