Merge 2 audio files in sox

Question

I am trying to merge 2 wave files into one file. The 2 files should start playing at the beginning of the new file. Independently of sound length. Running the following command

Answer 1

For cases like Calmarius is asking:

sox -m in1.wav in2.wav out.wav trim 0 `soxi -D in1.wav`

this stops at the length of in1.wav, for cases you know the shorter. Otherwise just add a comparator.

Answer 2

Heythere. Sorry for late response =) Command should look like this

sox file1 file2 file3

Above will merge first two files and name it after 3rd.

You also might wanna check the docs http://sox.sourceforge.net/sox.html

Answer 3

'soxi -D in1.wav' gets the length of the file (in1.wav)

Answer 4

just change -M with -m

-M = merge
-m = mix
