Question about normalize-resample.sh

[yxixi]

Thank you for your great job! I have a question when I tried to run the project.
I set 'N' as my CPU core number , then I input 'chmod a+x normalize-resample.sh'.
However, after I input './normalize-resample.sh ', there is no output on the command line. Is this normal?
Furthermore, what is the function of this script?

Next, copy utils/normalize-resample.sh to root directory of unzipped data folder. Then:

vim normalize-resample.sh # set "N" as your CPU core number.
chmod a+x normalize-resample.sh
./normalize-resample.sh # this may take long

Looking for your reply!

Hi, @yxixi

• Yes, there will be no output on the command line.
• It converts wav files with arbitrary sample rate into 16kHz, normalized wav files.

According to my recent study, you may simply skip normalization. It won’t affect much.
