On the use of asymmetric windows for reducing the time delay in real-time spectral analysis
The idea of asymmetric windowing as a way of reducing time delay in spectral analysis is explored. Traditional windows are analyzed in relation to time delay. Some asymmetric windows are introduced and a comparative analysis with traditional windows is made. It is shown that it is possible to reduce...

| description | The idea of asymmetric windowing as a way of reducing time delay in spectral analysis is explored. Traditional windows are analyzed in relation to time delay. Some asymmetric windows are introduced and a comparative analysis with traditional windows is made. It is shown that it is possible to reduce the time delay up to about 25% of the analysis window size. Application to linear predictive speech coding is analyzed, and the experimental results of using an asymmetric window on a standard LPC vocoder are presented.< > |
