Copy a same audio file multiple time in another audio file

Question

I have an audio file on my Linux system. Let's say a 2 second .wav file. I want to copy the same audio file 50 times into a new b.wav such that the duration of b.wav will be 100 seconds. I tried like this:

for i in {1..50}; do cat a.wav >> b.wav; done 

But it's not working. Please suggest a solution.

Answer 1

Never mind. Got it.

sox a.wav b.wav repeat 50

Refer to this question. Loop audio file from the command line (gapless) or into new file
