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 does not give me this result.

  sox -M new_input.wav myrecording.wav output_test.aiff

Are there other ways of achieving this through sox or other command line libraries?

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.
