As an edge is crossed, one side or the other dominates the window, and the output switches sharply between the values.

For relatively uniform areas, the median filter estimates the gray-level value, with particular success in the presence of long-tailed noise. The median is the maximum likelihood estimator of location in the case of Laplacian noise distribution. The filtered image is obtained by placing the median of the values in the input window, at the location of the center of that window, at the output image. The median filtering process is accomplished by sliding a window over the image. Median filters are useful in reducing random noise, especially when the noise amplitude probability density has large tails, and periodic patterns.

But for full-range music and sound effects, frankly I wouldn't want the distortion that it inevitably introduces.

And perhaps for the small 4%shift that the PAL speedup introduces, it might not sound so bad. You can get decent results with voice, because the frequency range is more limited. I frankly don't buy Blight's assertion that it's relatively easy to do. On the other hand, true pitch shifting, in which the duration of the sounds are preserved but only the pitch is changed, is a very difficult nonlinear problem in the general case. And more importantly, all of the important relationships between frequencies are preserved when you do a simple speedup or slowdown. That's less than half a musical step a concert B-flat is 466Hz. So for example, the concert A at 440Hz would be shifted up to 458Hz. But it doesn't seem to me that a lack of pitch correction should be a big deal.Īfter all, the speedup is only 4.2%. OK I'll freely admit that I haven't viewed PAL DVD material first-hand.

TimeMachine is a DirectShow filter allows to shift sound when film playing. I wonder if these could be used in DVD mode?, they worked on some VOB trailers I have on my hard disk.

Just install the filters and then in Zoom Player right click Filter Properties and then choose either Time Machine or Speed Machine and prepared to be amazed.

Vigovsky Alexander is the king of the up and coming directshow filters. To say these are amazing direct show filters is an understatement. I quickly tried them out with some XVID/DIVX movies that I use for films like A Bugs Life and the time delay/advance and picture/sound speed up work amazingly well for a 0.1 release. From the author of the excellent AC3 decoder come some great directshow filters which work very well in Zoom Player.
