Bass, kicks and and low frequency audio

Was communicating with Speck a while back about low frequency audio and he encouraged rambling here.

Of our three favorite low frequencies in the master mix channel topics (1) cutting bass below 20, 30, 40 or 50 Hz depending on the vibe, (2) centering bass below 80 to 200 Hz within mid-side mixes, and (3) eliminating stereo signals by creating a mono signals below 80 to 300 Hz depending on the vibe, a few words about (3).

If you are not familiar with Tone Projects freeware VST plug in TP Basslane, try this magic plug in within your master channel after iZotope Ozone (or equivalent mastering plugin) and adjust to taste. When your bottom is flabby, Basslane may tighten up your mix for zero dollars. Easy and simple to use.

All fine recommendations, Fisherman.

This is how I treat the low end quite often:
I set all below 100-120Hz to mono and set hipass to 25-30Hz to gain some extra headroom. ~50Hz is usually where my fine lows of the kick drum lives so I tend to lift it up a bit - the drawback is I’m losing some total headroom, but I think it’s worth it.

Quite often I find myself using multiband comp to tighten up the lows on the “music” sub mix channel. This is my sub mix channel which has everything else except drums and vocals.

Does the plugin work with Ardour?

I thought this might a good place to add a basic EQ chart for overall balance before you get to the finer points of mixing. What do you think?

never hurts to know one’s place ………… within the frequency spectrum

Basslane VST is a Windows plugin, Ardour manual makes a compelling case to run away http://manual.ardour.org/wo...

I guess Ardour is not free as in beer, but free as in wine.

The best explanations I have seen come from Steve Duda and DeadMau5 who may seem glib but knows what he is doing.

1 - Why cut the Bass?

Conclusion, is to cut below 20Hz on the master chain.
Engineers Filter VST

If you do not strip off the sub-bass then it acts like an offset to all the higher frequencies and may push them into limiting and distortion.

2 - The low end
This discussion is mostly about creating a clean and detailed low end.
My link starts a bit early, but Steve continues the discussion from how we hear sounds, drums and how to buss them and then about the low end.

Re: centering bass below 80 to 200 Hz within mid-side mixes.

A stereo Bass is fine as long as it does not lose any of its bass when summed to mono. This was covered in Computer Music magazine some time ago, along with the methods of doing that.

I mainly use the Harmonic Maximiser in this package …

JUST BE CAREFUL WHEN DIALLING UP THE LO MIX LEVEL.

also remember that most bass in processed music is around the 90-200 Hz ball park there is a fine line between BOOMEY bass and Warm bass without loosing the definition !

Watched an interesting tutorial about enhancing the loudness of mono bass drum kick playback without turning up the kick drums volume. While I am happily unfamiliar with loud teeth rattling bass in my car, I did investigate the tutorial’s technique and it was interesting and useful.

Solo the kick below 80-125 Hz range and observe with your favorite stereo image analyzer. If the kick shows no stereo information (mono) slightly widen the stereo field. For the same range below 80-125 Hz, use a harmonic exciter to increase the audio information. Using a tube circuit model (Ozone Exciter’s Triode mode for example) introduces more directional awareness and vibration (shaking).

Is that what John Bonham did with his right foot?
