Us<strong>in</strong>g short analysis w<strong>in</strong>dow (short frames)<br />
Assume the follow<strong>in</strong>g:<br />
<strong>Speech</strong> is stationary <strong>in</strong> each frame.<br />
Static acoustic impulse response (enables track<strong>in</strong>g objects).<br />
Real room acoustic impulse response:<br />
Reverberant environment (long T60)<br />
Long impulse response – takes <strong>in</strong>to account late reverberations<br />
Discard MTF assumption.<br />
Instead, work <strong>in</strong> STFT doma<strong>in</strong> [4].<br />
Comb<strong>in</strong>e with Cohen method [3].<br />
