how can I simulate tape saturation/hiss?

[jordex]

I love the warmth you get from crackling of tape in recordings. I've noticed that there's a lot of it in hip-hop songs, and other genres as well of course. It could even be the crackling of Vinyl as well, maybe. All I know is that I love it.

I'm wondering what I can do to simulate it in my songs since I make most of my music digitally.

Anyone have any ideas?

Listen to the song Over and you can sort of hear what I mean. It streams at such bad quality so it's sort of hard to hear, but I think you get the idea.

I am not sure if it can be done by simulation, but I think this is what you are looking for:

ahh yes
definitely something along those lines

thanks! i'll try mixing that in

You could also try a VST effect by izotope called vinyl.

Ahhh perfect. A VST is what I was looking for. Ah and it's free too!
I'm downloading it right now.

To make sure you're getting the most realistic tape sound make sure it is attenuating the peaks(attack) transients by -6db. Tape on average cuts 6db from the transients, which gives a compressed sound, along with slightly distorting harmonics to give what appears to the human ear as a very warm and rich sound. Would kinda be a hassle to do this manually all the time, but IMO Izotope is one helluva company and makes some top notch plugins!

Been using this for years, very useful. Only problem is that is it has a tendency to remain active and cloud your entire track if you don't automate the effect to turn off when you're done using it in the pattern.

Agreed, plus I've noticed that it only has like 2 or 3 different dust samples and you can notice them loop in a pattern after only a few times through, overall I really don't like it.

Sampletanks phonograph effect is really nice actually, too bad it doesn't come as a VST, maybe I'll just sample some of it sometime and run the rest through vinyl's age filter.

Just to clear things up.
Is the crackling/saturation from things peaking on analog tapes?
Or is it some other phenomenon that causes them to saturate?
