[FFmpeg-devel] acrossfade duration accuracy

I am getting an unexpected number of samples in the output of the 'acrossfade' filter. In the following example I would expect acrossfade.wav to contain 72,000 samples but it only contains 70,976 samples. Am I doing something wrong? [root@ryan ff]# ffmpeg \ -y \ -vn \ -filter_complex " \
