DeepFilterNet adds broadband ticks at word edges when the input was already gated by Chrome's WebRTC noise suppression

Browser takes from getUserMedia({audio:true}) (Chrome noiseSuppression on by default) fade room tone to digital silence between words. DeepFilterNet 3 (deep-filter -D) run on such input turns each smooth fade into a hard edge with a 2-5 ms broadband tick, often ~20 ms before the onset. Listeners call it tearing. Lowering the attenuation limit (-a 20/12/6) doesn't help. On ungated input from the same pipeline DFN adds none.
