Stereo to Mono - using avisynth audio function ?

[Dark-Cracker]

Hi,

i just want to know if this way is correct to convert a stereo file to mono.

1) i get the left and right channel of the stereo file (using getchannel)

2) i merge the 2 channels in one (using merge channel)

3) i duplicate twice the merged channel to have a dualmono output file.

----

A) is this correct ? or i should use some matrix to keep correctly the balance beetween each channel.

B) can i do the same for a 6 ch file ?

if anyone have some suggestion feel free to post them :)

Bye.

That's the same way the vast majority of audio processors do it. There are ways to avoid certain audio dropouts that can cause, but I don't think it's possible in pure avisynth.
