Thank you VERY much ! That woks (macOS Mojave) I created a finder action to batch normalise samples: export PATH=/usr/local/bin:$PATH for file in "$@" do sox $file outfile.wav --norm=-0.1 && mv -f outfile.wav $file done but there is a problem when the path contains empty space :/ Still need to find a solution for this.
