连接两个WAV文件，然后在SOX中合并第三个WAV文件

Question

I have 3 wav files: 1.wav , 2.wav and noise.wav. I want to concatenate 1.wav and 2.wav in output.wav an then output.wav merge with noise.wav with a single SOX command. I know how to do this in 2 step. Is there a method to do in one step?

this is how i do it:

sox 1.wav 2.wav output.wav
sox -m output.wav noise.wav output2.wav

Answer 1

After hours and hours of trying finaly i find a way to do this:

this is the anwser:

sox -m "|sox 1.wav 2.wav -p" noise.wav output.wav 

where 1.wav, 2.wav and noise.wav are file localy stored and output.wav is the output generated by SOX.

I hope this save others time. I serch over the internet for this answer for days and no luck.
