Dynamic bass boost

Hello HA i want to ask and get help about something.

First, i have an old big amplifier from the 2k, it has a T-BASS button on it, with 3 levels, same for a BBE button with 3 levels.
The T-BASS control amplifies the bass and it doesn't compromise any other frequencies, it's like the bass is playing from another place and that is cool, the BBE clarifies the sound a lot.

Now what i want to do is, have those effects in my computer, i suppose the bass used in the amplifier is a dynamic bass boost, right? and the BBE i really don't know.

Here is the catch, is it possible to capture those effects using a simple realtek HD audio soundcard from the amplifier and create a convolver .wav file? maybe using some convolution software? or is there a way to emulate dynamic bass boost?

I am using foobar2000, the goal of this is to have the same effects as my amplifier, no matter what the method is but make it sound almost exactly, my amplifier won't last forever and this would help me learn about how to create my own impulses.

Again, no make and model information. This is a good chance to practice one's powers of omniscience!

My best guesses are that this is either a musical instrument product or an Aiwa audio component. Possibly a JVC but there seem to be fewer of them than the Aiwas.

I suspect that it is static bass boost. Just a bass equalizer with presets.

BBE appears to be a treble "Enhancement" scheme that may include adding nonlinear distoriton.

I don't have a lot good to say about the flexibility and power of soundcard built-in equalizers.  The equalizer plug-in for foobar may be better.

You might also want to look at the freeware: Equalizer APO if you are running a version of Windows that is new enough to support it.

You can get BBE Processors and a software plug-in, but the plug-in seems hard to find and it may have been discontinued.

Personally, I have a bias against "secret" audio processing.

T-Bass stands for "turbo bass", but those in the know prefer the more advanced SDT-Bass, which is of course "super duper turbo bass". 

BBE is an example of an aural exciter. Other companies such as Aphex have made these and were a bit more candid about what they did to the signal, predominantly some harmonic synthesis and high frequency EQ. They add some "zing" to the sound, if you like that sort of thing.

Thanks for all the answers guys, i have read them all, and yeah my "amplifier" is an old AIWA stereo system.

There it is, i usually just connect my headphones to the headphone jack and turn on the super t-bass on either with remote control or one of the buttons there, for the BBE effect i need to press one of the buttons there as there is no option for it on the remote control.

I will get my hands on that BBE software but the problem is how to emulate the awesome bass from this "amplifier"? i can say it is an amplifier right? i have been unsure about how to call it.

Some people told me it was dynamic bass, the same goes for my little old portable 4gb sony walkman mp3 player, it has a bass button and it increases the bass by a lot and doesn't affect other frequencies, is almost un-noticeable and the bass is good.

Is there a way to emulate this kind of bass on the computer? if it is just an eq setting maybe it is one with more bands or something, most eq i tried on the pc seem to always screw up with vocals and instruments and even there is "cracky"sounds because the bass is not well adjusted.

With all those years working in and around sound reinforcement I find it odd that you would seem so unfamiliar with BBE.

Much of my SR work was made using equipment configurations that I had some influence over, and the musicians I worked with agreed that we wanted to keep the systems as clean as possible.  There was lots of eq, but almost no EFX.

However, in roaming about the earth looking at other people's SR rigs, I don't see that much BBE. More Aphex, but mostly neither.

These days some pretty impressive EFX are built right into the console, especially the digital consoles.  I've done most of my SR work on a digital console, lucky me!

Sure, its called narrowband eq, and the best implementation of it is called Parametric Eq.  By narrowband eq, I mean graphic equalizers that have sliders for every 1/3 octave which is about 30 in total. Most consumer eq is composed of 5-8 bands that are several octaves wide, and that makes it darn near impossible to kick up some frequencies but not touch the others.

If you've got 1/3 octaves to work with, its a lot of knobs and it may take you a while to get comfortable with what they all do, but the bands are narrow enough so that you can be pretty selective. 

However, the silver bullet is called Parametric Eq, and you get to choose the width of the bands and position their center frequencies precisely. This is so powerful once you get into it, 5 bands of parametric eq with 15 knobs in total, is generally considered to be a better tool than 30+ band graphic eq. with 30+ knobs.

As far as the PC world goes, it seems like the ideal tool for adding parametric eq would be Equalizer APO with one of Julf's parametric eq apps plugged in. I'd recommend it in a heartbeat, but while I've got Equalizer APO working with the basic graphic eq app, neither of the parametric apps are working at all. I click them, the start and end without even putting up a window.

There are a ton of what are known as VST plugs that are parametric equalizers, and I've used some of them with Audacity. There is a VST plug adapter for FB2k, but when I try it these days it crashes immediately.

No joy! 

Right now I'm stuck with Equalizer APO and the basic octave graphic eq, which still seems better than any of the sound card eqs that are at my disposal.

So then I got some PEACE:

PEACE Parametric Eq for Equalizer APO download

This appears to be the system Eq solution if you are running Win 7 or 8.


Would begood to have this to work somehow with foobar, so we can convert some audio files with the already applied eq settings, like we do already just using the dsp chains.

And on top of that we don't know the exact parameters of "SUPER T-BASS" or any of that bass that comes with most hardware.

PEACE + Equalizer APO will definitely work with FOOBAR2000.
