Now, dear sound hunters, you got the tool to test how good your bass system is. This signal is even lower than Wiliamsson's famous HiFi curve from 1950. He meant that a good speaker should cover the range 20 Hz to 20 kHz.Lower or higher is mmeaningless, because we cannot hear. So, if you play and hear nothing, it's not an empty file.
