Increase the volume of the sound file?

The above sound file: 1.wav.
It has very little sound. How does it increase the volume?

Is there such a program statement?

can you please explain in more detail about what you are trying to do

I think you just need to fix it with a PC program. Try this:

AA.txt (22.9 KB)

Rename to AA.mp3

Modified with Audacity software (on Windows OS).

Yes, as @ChrisWard said, your sound (A.mp4) should first be normalized (+32db), e.g. with Audacity.
