when u use cut u get a small resonance that can interfer in the wave......
shelf u are doin the cut without that resonance....
maybe there exist some kind of filter which wont add this small resonance but i dont know.......

its pretty hard to process exact frequency ranges, a reason why it is not that often used. anyways, i like it to use as kinda fading tool sometimes. its good for rough work imo.... keep in mind it is limited in its cut/boost range, maybe this answers your question 
besides there is no "use this for that" ....
cheers

Shelf is a more natural than a cut.In nature there aren't any sounds like with a lowcut.But many like with a shelf.A bass will sound more natural wich does not mean better.
Shelf is good if you want to keep all frequencies,and lower just the unwanted a bit less or a bit more.
Hey Stephan..I send you soond that post bro,sorry for the delay with the post,busy time here.Best Greetings from Hamburg

A low cut says "I'm going to get rid of all frequencies below this point completely"
A low shelf says "I'm going to make all frequencis below this point a little quieter" (or a little louder)
Obviously these aren't complete and accurate descriptions of what each of these EQ shapes actually do, but that's the general idea of both of them. It should hopefully be fairly obvious from these descriptions where you would use each in your own production.
BTW both shelves and cuts can introduce resonances around their turnover frequencies. Some shelves have Q controls which explicitly controls this. Cuts and shelves, both high and low, are also both found in nature.
I use shelves and cuts (both high and low) about equally.

Colin where do you find a lowcut in nature ? It really is interesting to me,since it was today maybe half day ago,I heard exactly this sentence I mentioned above with lowcut in nature..directly from my teacher,exactly on this topic.
I'd like to tell him an example of a low cut that you can find in nature.

When there is too much wax buildup in an ear.
Or when you listen through a wall/pillow.
I guess, a natural highpass would be listening to something under water.
Is that what you meant? |

one of the craziest 'nature mixes' I ever experienced was with a belly full of hoffman at a dark psy party in the high desert of oregon....
main stage was too fast and heavy for me and a couple of others so we were hanging out at the renegade chill stage which had a small hill of dirt inbetween us and the stage...just far enough away and just enough dirt so that it acted as a staggeringly effective low-pass filter, to the point where it was like adding a subby chunky bass layer under all the dreamy chillout
AND THUS AMBIENT CORE WAS BORN
cracked so many partiers up over the night, and fused PERFECTLY with everyone's chemical of choice.

Interesting what you've written ..Main Coon you listen through a wall you have more a high cut than a low cut..than I dont know ,I know that it is a kind of natural filter ,Im gonna ask for clearification me.
Will - nice story  ,but i guess this was also a high cut not really a low cut the lows had more a shelf or decreased just in db.But interesting to read your movie.
..Main Coon with under water seems to me also a ineresting thinking.Thanks for suggestions.Lows have basicaly more energy,much more,the highs are absorbing fast.Distance is one point ,obstacles are hard for highs but not for lows.
Im gonna ask tomorrow and am curious cause I think he give me another logical explanaition.

I guess the thing about obstacles, walls and stuff and lows seem to get thorugh better has to do something with wavelenghts and material....just a guess tho

In my opinion the major difference is that with a lowpass (or hipass) your boost/cut raise/reduce by X dB/Octave, a shelf is a "fixed" (not really fixed) cut/boost.

I hadn't read , yes, it's a fixed amount. |

i like a lot shelf filters ,it work great for shaping the sound ,to make it sit better in the mix , hp/lp i use these for cuting unwanted frequency but i use them rarely in the low end, phase shift introduced is not really transparent in the low , shelf can sound more natural.. but plenty of producers cut kick and bass with hp filters and get great result ,dunno why most of the time i don t like it in my tracks.(it could be just cause i dont bother trying some eqs to find a hp more suited for cuting the low )
for bass i often boost a bit the low end with a peak filter then i use a shelf with no resonance to cut and shape the sound ,i find it flexible to adjust to amount of bass in the kick and bassline that way.most of the time the peak dont boost at all or just a little after the shelf is tweaked ,it s just help to get a more tight controlled low end.
you can tune the sound that way , for example a kick ,you can boost with a peak in the low where it sound good with the bassline then use a shelf to make it sit well with the bass (it s the same thing but explained in a other way )

) a wall gives the equivalent of a high shelf which reduces the level of high frequencies by a fixed amount. The air itself is a low-pass filter, with a cutoff depending on humidity and distance, amongst other things.
