Newpipe and Just (video) player have this function, but the former cannot play offline files and the latter cannot play audio files. I can rename the audio file to mp4 and play it in Just player, but it doesn't have a background play option.

From what I've searched on the net, in both apps the feature us implemented from ExoPlayer. On F-droid, Auxio audio player mentions ExoPlayer, but does not seem to have the feature available.
Are there any foss apps that has the feature to Skip silence for audio files?
