Hot to do that.... ? - Visual Basic .NET

Doug Zody

I have wave files being recorded for interactive voice enabled application.

Currently I have more than 1000 wave files implemented in the application.
Since I have recorded using regular desktop PC the quality of the sound is
not good. Also the volume levels in each of the wave files are different.
So what is happening is when I play more than one file at time, end user
will hear some of the wave file in one pitch, some of them with different
volume level making it an unpleasant experience for the end user.

Is there any way using .Net application I can redit these wave file to bring
atleast volume level of these files to the same.

Do I have understood the file system where exactly the volume level is
stored in the wave file?

Your reply is highly appreciated.

There is no volume level stored in a wav file as a single setting. The
waveform recorded is just stored. So soft sounds are represented by
small numbers. What you are looking for is software that can normalize
your wavfiles. Maybe this can help:

I have not tried it, but it looks to be free software for just that
purpose.

Regular desktop PC's can record just fine. If you get bad sound it's
usually de microphone that is to blame.
