Does it or does it not? If you don't know, why the patch?
It improves the window in the sense of mathematically matching the Kaiser window expression due to the improved bessel function accuracy. That claim I have verified and placed in the commit message with evidence. What that translates into in terms of resampling accuracy, I don't know. Normally, such things do help reduce the noise floor, but I don't know an easy way to test via FATE or associated tools. I put that caveat in the bottom lines of the patch. > _______________________________________________ > ffmpeg-devel mailing list > ffmpeg-devel@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-devel _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
