Just curious, what degree of slope do you use on an LPF to best portray distance? Such as doing SFX for a distant object approaching, or changing perspectives with different proximity to the object.

It would all depend on what elements were playing around it.

Is the sound featured or subtly blending in with the other elements? Is there dialogue at the time? Is it playing against loud rock music or a classical score? Is it competing for the same frequency space as any of the other elements? Each sound will dictate how the other is eq'd depending on how it is supposed to sit in the mix.

Well for what I am working on right now, its the primary sound with virtually no other competition in the spectrum (or on screen for that matter). I mean more in general though, without regard for mixing. More from a sound design perspective than a mixing perspective.

Ive been using a 1 pole filter thinking a gradual slope sounds natural but am pretty new to this so I thought Id see what others had to say.

I've had to do this many times and while I am not an expert I can offer these tips:

Roll off the lows gently. If you use a steep roll off it sounds unnatural and cheap but if you work with the frequency and rolloff curve you should find good results. Secondly, use a high shelf just gently and experiment with the freq. It is surprising how much high frequency detail can travel a distance - often people cut off the highs completely and this sounds fake and filtered. A mid boos with pretty sharp Q can also help give distance i the boost is in the right freqs. After EQ , try a small amount of reverb and echo can help give some atmosphere and sell the effect.

I either use the lowest slope, usually that's 6dB per octave, or I use shelving filters...
