Compressing Audio file

Hi Friends


I have an audio file which i need to compress.
i have winxp which compress about 50 % of the orignal file size...

on the other hand i want to compress and decompress it using pkZip from the command prompt....


1. First tell me hjow to execute a command from command prompt in vb....

2. whcih compression v can use to best fit our problem...


:confused:

to run something from the command line

VB Code:

Private Sub Command1_Click()
    Shell "cmd /k ""your command here"""
End Sub

now then, why not simply convert the sound to a compressed format? you can go lossless and still compress it to about 50%

there may be free conversion plugins out there, and there are definitely free conversion programs out there
