I am trying to learn some things about Hokusai too. I found a clip of a record scratch, which has a bunch of silence before the actual scratching sound and I’m trying to find the same way to get rid of all the silence. Is there an easy way to do that? I know there is probably a way to somehow move the recording head where the play head to where I want it and which I’m still trying to figure out and then cut out the silence, but I am trying to see if there’s another way to do that. Any help would be very welcome.
