Comment (by cus):

 Well, the filter can only measure what is passed through it, and the
 filter only supports 48 kHz and double sample format so it works as it
 should.

 You can either
 - make this ticket an enhancment request to add support for 44100 Hz and
 non-double sample format to ebur128 filter OR
 - resample manually to 48 kHz first using a fixed point sample format
 before invoking the ebur128 filter: `ffmpeg -i 3_45.flac -af
 aresample=48000,aformat=sample_fmts=s16,ebur128=peak=sample -f null
 /dev/null`
