  I am attempting to truncate a .wav file from any length to 1 minute by using the ffmpeg package. once truncated, I want to save the file in another directory.

  I am able to do so with he following command :

  ffmpeg -i ~/test/audio.wav -ss 00:00:00 -t 00:01:00 -async 1 ~/test/test-minute/*.wav

  But my issue is that I would like to be able to iterate through multiple files within my /test directory and truncate each .wav file, then place the new file in the new /test/test-minute directory.

  Also, I would like to keep the same name for each file when it is created in the new directory. Thus, when a copy of audio.wav is truncated to 1 minute, the new file will also be named audio.wav in the other directory.

  In short, how do I perform the truncate process across the entire directory ?
