question about ffmpeg-normalize

[somepayphone]

hi~ i meet with a problem when doing ./normalize-resample.sh , it seems that wav in /tmp did not exit, i try to fix it but failed, does anyone know where the problem is ? i also run the commend " ffmpeg-normalize 1.wav -o 1-norm.wav" to test this normalize tool , and occured the same question ; how to make this normalize tool (ffmpeg-normalize） work？
