Doesnt work

mostly got this from hasan having it, pls have it work with soundcloud

DO NOT INSTALL. INSERTS POPUP ADS ON ALIEXPRESS.

Ciertamente aumenta el volumen sin mucha distorsión. Excelente Add!!

I really wish it worked but, alas, it doesn't seem to do a thing. 20 % and 500 % sound exactly the same.

Does what I need

Doesn´t seem to work

Does absolutely nothing.
