Hey guys, I need some help here with a big school project. It involves music and memory. Basically, we need to vary the amplitude of the music played; problem is, we don't have a sound meter to measure the decibels and we can't find an audio software that can measure the amplitude or decibels of the music.
to put it simply, is there any software or website that can adjust the volume of a video or song? we're thinking of ~80 decibels and ~60 decibels. maybe something we could run the song through, or even something that could measure how loud a song is, so that we get an objective standard.
i hope this question isn't too confusing. this is a pretty big project so any help would be much appreciated, thanks!
