Sox mix and delay

Question

I am mixing audio using SOX.

the command SOX -m voice.wav audio.wav final.wav is what I am using.

My goal is to delay the voice.wav of 10 second

Answer 1

There are a couple of options:

sox -M f2.wav f3.wav f1.wav out.wav delay 4 4 8 8 remix 1,3,5 2,4,6    

(assuming stereo), or

sox -m f1.wav "|sox f2.wav -p pad 4" "|sox f3.wav -p pad 8" out.wav     

The second way is probably better since it works with files with any number of channels.
