how can i mix to wav file to one wav file ?

how can i mix to wav file to one wav file ?

how can i mix 2 wav files to 1 wav file ?

Although it is not VB related, .... i can suggest you use a program called SuperSonic. Or just load the second wav file into the first one using Sound Recorder (installed with Windows).

open the two wav files for binary access, then get the length (lof) of the shortest file (so you dont create errors by writting in space that isnt there) then create a new wav file and copy both the wav files binary info into the newly created wav file

VB Code:

open "wav1.wav" for binary access read as #1
get #1, , Mystring1
 
open "wav2.wav" for binary access read as #2
get #2, , MyString2
 
open app.path & "wav3.wav" for binary access write as #3
for i = 1 to len(MyString1) 'Place shortest file length there
put #3, , mid(Mystring1,i,1)
put #3, , mid(MyString2,i,1)
next i
 
close #3
close #2
close #1

Something like that, i aint even tested it but follow that principal
