Audio Silence Remover Pro helps to remove silence from multiple audio files together. You can just give it a list of files to trim as opposed to having to do them individually. It scans silence at the beginning, middle and end of input audio tracks and removes silent part(s) automatically.
This software can set 'Maximum silence duration to be left at the middle'. This option specifies a period of silence that must exist. By specifying a higher value, silence that is wanted can be left in the audio.
