removing silence from a directory of wav files

[MelikaBahmanabadi]

Hi,
I used the Rhasspy-silence framework for removing silence from one audio and its chucks are making in the split folder with 0.wav, 1.wav and etc with the below command:

sox /home/AudioFiles/first_audio.wav -t raw - | bin/rhasspy-silence --quiet --split-dir splits --trim-silence

How I should remove silence from multiple wav files in a directory and the split folder keeps all chucks related to all audio files like this:
first_audio_1.wav, first_audio_2.wav, ...
second_audio_1.wav, second_audio_2.wav,...
Thanks
