Another Voxengo plug-in is available for public beta testing. It will be a commercial plug-in - so, if you do not betatest 'for free', do not bother.

The plug-in is called LF-Max and its main function is to add sub low-frequency content. Beside this it features distortion module - like the one found in LF-Punch plug-in. Signal flow is different, however. LF-Punch processes low-frequency band 'inplace' while LF-Max mixes distorted result with the original low-frequency signal.

Parameters:
Center - cutoff (center) frequency of the internal crossover filter.

DistDrive - power of the distortion applied.
Filter - high cut filter's frequency: with this filter you may remove higher harmonics after distortion is applied.
DistGain - amount of distorted signal added to the output.

Sub Gain - amount of sub frequencies added to the output. Sub frequency generator works with the low-frequency signal extracted by the internal crossover filter. If it's tuned to 128 Hz this will generate 64 Hz 'sub' signal. This works pretty well in most cases and 'fattens' the sound a lot, and even imparts some presence effect probably due to psychoacoustics phenomenon.

LF Gain - signal gain of the original low-frequency band.

Out - overall output gain control.

Monitor switch bar allows you to listen to different signals inside plug-in.

Setup executable is here:
(please note that it is in the temporary folder now - it may be removed later).

BTW, I've tried to mimic finite wordlength on all processing stages of the plug-in. Theoretically, plug-in should have the flavor of outboard 24-bit DSP processors.

I've been searching for exactly this ever since reading about the production of Soundgarden's Superunknown. Part of the magic of that album's sound is added subharmonics (probably done with a harmonizer unit). I hope you can expand on this bigtime in the coming weeks. Very cool idea.

sounds good...will give a go...

"Jason's a genius-another thing he did that I thought was really great was on the Soundgarden Superunknown record. After they recorded the bass they took it off tape and put it through a dbx boom box, a subharmonic box, ran that out through a P.A. and filled the room up with just sub bass. Then they remiked that and added that into the sound, making for an insane amount of bottom end on that record."

Aleksey - this plugin has amazing vibes. Leave it to Voxengo to get the vibes flowing.

Any chance of a wet/dry knob to leave the original signal untouched and just blend to taste? (Although it seems the center frequency/filter does pretty much that with much of the signal in a way.)

(Thanks for that link, Mully!)

This sounds interesting Aleksey and is a bit how I've been working with LFPunch, instead of punching the kick or bass guitar I'm dialing it down to the subbass region an octave below - and punching whatever is down there.

This new creation might actually be more of what I need for rebalancing than LFPunch. I think it could also be similar to the sounds I tried to get out of PSP MixBass but couldn't quite tweak it to what I needed.

Is there any possibility for you to consider putting a compressor/limiter (that reacts kindly to bass envelopes) on LFMax with a single threshold control? Kind of like the one on LFPunch?

Another excellent innovation Aleksey

I will have a lot of enjoyment testing this one today!

First opinions -- this may be the best sub-bass VSTi out there

Oh - wait a minute - this is a mighty fine bass/subbass EQ for me to rebalance full mixes with in the batcave here! Even without adding distortion and whatnot...I might even run it after LFPunch.

I'll take one please with or without comp/lim (it may not need it)...

Jeff, in this plug-in you can already use wet/dry mix. All three signals (distortion, original and sub) have a separate gain control.

Kyle, my that was exactly my thoughts - LFPunch after LFMax. LFMax for sure can't make what LFPunch can, and vice versa. I personally feel there's no need for sub signal compression - let it go 'oomph'.

I've made the first version use 25-bit DSP imitation by accident.

Here's an updated version:

mmm smells like Phat Pro

Aleksey Vaneev · Post by **Aleksey Vaneev** » Sun Jul 31, 2005 12:29 pm

Aktion, not quite. Actually they are very different in performance and the results you can achieve. But I agree that both are competing products. Waves MaxxBass I guess is also of this league.

Aktion · Post by **Aktion** » Sun Jul 31, 2005 12:37 pm

Yeah. and MixBass. Not much products to fill the market.

Yes I see - I've tried it and I have more control over LF and Sub than I've ever had. Who says you can't add bass content if it isn't there (I guess I did once - can't say that now!). If there's a little down there then I can make it grow like sprinkling water on a dry flat sponge, rebalancing LF & Sub is a lot better now too using these 2 tools (LFMax & LFPunch). Ooomph it is !

JeffSanders · Post by **JeffSanders** » Sun Jul 31, 2005 5:58 pm

This tool is beautiful. So far, works flawlessly in Sonar 4.

Just 2db of extra sub frequencies on my bass tracks and the three-dimensional illusion in my songs is much more pronounced. And gives me a nice feeling in the gut

Thank you for this one...when can we buy it??!

(btw - I guess I was asking more about a "mix" knob then "wet/dry". But I guess it's not necessary here as you said, Aleksey...)

Works great on Logic for PC. No errors founds; sounded really nice during my tests.
