These clips are hand picked that i used for sounds on my layout. The clips seem to have more full frequency especially the lows probably from better quality microphones than what you would expect from smartphones or low end camcorders. I have edited some of these clips through Audacity to provide the seamless sounds i want. These edited sound clips live on my computer and i bluetooth them to a large full frequency bluetooth speaker.
