Is there any form of sound editing/mastering software out there (freeware or not) that I could use to clear up some stuff in a demo CD for someone? My brother gave me a demo disc of his band, but I want to get rid of the hiss (not sure what it was from, I think he said it was because of the recorder), and possibly put a bit more bass into it. If there isnt any, is there any audio recorder that I could DL/buy to rip the songs to wav format? I could use my EQ to clear it up a little bit by recording it from CD to my line in, but sound recorder only records so much before it stops. Thanks in advance, Matt.
