I'm sorry if a question like this has already been answered, but when I am dubbing something or putting together really anything that needs background music, I usually record that music onto one track, and then add my lines or etc on another. For some reason though, my voice will come out fine, but the music is being recorded either not at all or so low only dogs can hear.
I think it might have something to do with a program that I used to have but now no longer have & for the life of me I can't remember the name. It had different playback effects to simulate environments (normal room, padded room, cave, theater, etc) and a speaker tester that generated a bee buzzing or what they called 'loopy music' I think. I don't remember what else it did but that's all I ever used it for.
If anyone could help me with the first problem if it has nothing to do with the lack of this program I can't name, that would be great. If I don't need it, then I don't mind as much, but if I do I'd love to see if anyone can help me with that as well.
