I see only 751 records in the outfile. How ebur128 works? Is the file

ebur128 can do it, if you change one line:

Change line 218 int ebur128.cc to

=C2=A0 =C2=A0 =C2=A0fprintf (F, "%5.1lf %8.6lf %8.6lf %6d %6d\n",=
v, nm / km, ns / ks, hm [i], hs [i]);

recompile and install. Then

=C2=A0 ebur128 --prob --lufs somefile.wav

and then in gnuplot

=C2=A0 plot 'ebur128-prob' u 1:4 w i lt 3

or

=C2=A0 plot 'ebur128-prob' u 1:5 w i lt 3

Ciao,=E2=80=8BOk, w=
orks but I have a couple of question.
