As much as I don't like Deadmau5 or most of his music[...] It's good engineering.

"Acoustics" and "audibility".


Bass you can feel, bass you can hear.

There is definitely a lack of bass in this tune that you can hear. If anyone disagrees with that, they're clearly deluding themselves

Wait a minute, are guys talking about bass?

Nope. A "vibrating video" doesn't mean shit in terms of bass authority. It's a visual interpretation.

Again: This is about PERCEIVED bass. Which is the fun part of bass. While this track may technically go down low and loud here and there (I'm sure it does) it doesn't mean shit if people come telling you your track sounds weak in its supposed to be fierce and dirty sounding, filthy, filthy nether regions. Which is what happened here.

In case you missed this earlier point: Making a subby, subby sine wave is easy. It's 5 min of work if you know what you're doing. But if it's not layered right with audible information on top, it will feel just like that: A typical, flat sounding sub that's monodimensional. Looking good on spectrum analyzer? Sure! Will it light up a room with your Arduino? Yeah! Fun to listen to? Meh. Sounding phat and round and full? Not at all.

Easiest way is to just put the higher parts of a kick there, like Liam did here on FFWF, which is totally okay if there's supporting bass (aka a surrounding bassline or some sort of glorified 808 hit as in SMBU or whatsoever).
But there's nothing of that sort in this tune, leaving it feeling empty 'down there'...

"Liam has no idea how to write music with bass in it" is overcooking my statement. He very likely doesn't know how to frequency-sculpt. As much as I don't like Deadmau5 or most of his music, this guy has figured out a very musical way of sculpting a homogenous frequency image. It just "sits". It's good engineering. I don't think Liam likes to spend time on properly sculpting a track. On various occasions he made it clear he's bored of the more technical stuff. Which is, of course, totally alright and understandable. It doesn't help the music, though, which feels like someone didn't want (or know how) to put in the last 20% of effort to make it as funky as possible.

And yes: The job of a mastering engineer is NOT to put bass in a track that doesn't do it right by itself. Mastering is refining and improving, not repairing. People these days tend to forget that and send in shoddily mixed shit as mp3s, because of ideas like "mastering will take care of it" (or "let's fix it in the mix", one stage earlier). Get it right while writing the tune and see how everyone after you improves your stuff even further until it becomes amazing.

deadmau5? where? he's making progressive house mostly

Horrible circle breaks, then worship the freaks
The dog is barking mad, has gone and run away with no leash
The heat is coming, stop running, leave your blood on the streets
We stick together, stormy weather, we don't fuck with police
Go!

You bet you can't hold me down

We fight fire with fire
We fight fire with fire
We fight fire with fire
We fight fire, we fight fire with fire
We fight fire, we fight

Valiant troops, camouflage my soul if I cry
They don't give a shit whether you live or you die
Feel the heat and prepare for war
Raise your fist and reverse the war

We fight fire with fire
We fight fire with fire
We fight fire with fire
We fight fire, we fight fire with fire
We fight fire, we fight

So that's the thing. I often read you say you don't like someone's music, but that it's technically good. You like to school people about technical knowledge because you know stuff, good for you.
But in the end, I get the feeling you're trying to convince us that we shouldn't like something because of (technical) reasons.
So... what's your point?
