VST Small Speaker Bass Enhancer

Download the 4th prototype of the Windows VST-Plugin (version 0.6 - 22/05/2010 - 188kB) : or the MAC OS Audio Unit (AU) & VST (version 0.6 - 05/09/2010 - 586kB):

For the reason that the plug-in development uses the JAVA framework you need to have an installed JAVA Runtime Environment.
If you don't have the JRE (JAVA Runtime Environment) installed then you'll get it here:

Plug-in Installation:

Windows VST:
Just unzip the dedicated ZIP-File and copy the plug-in folder into your VST plug-in directory.

Apple Mac OS Audio Units and VSTs:
1.) Unzip the dedicated ZIP-File
2.) Copy SmallSpeakerBassEnhancer.vst to ~/Library/Audio/Plug-Ins/VST
3.) Copy SmallSpeakerBassEnhancer.component to ~/Library/Audio/Plug-Ins/Components

Important: To use the Audio Units you need to copy the *.vst as well.

The plug-in uses a technology called phantom fundamental which was already known to pipe organ builder hundreds of years ago.
Psychoacoustics shows, that a fundamental component can be heard even if it is just represented by its harmonics. An example would be two organ pipes playing at 100Hz and 150Hz where our brain creates a fundamental at 50Hz.
By using that technology small speaker with a cut-off frequency of 100Hz could be used to create a 50Hz phantom component which is just there because the psychoacoustic part of our brain extrapolates it.

Cut-Off-Frequenzy [Hz]:
The frequency range gets split up at the cut-off frequency to create harmonics for all tones below of that frequency.

Original Bass [Hz]:
Adds the original bass below of the cut-off frequency to the output. That is merely useful if your speaker can make use of that low frequencies.

Extended Bass [Hz]:
Adds the harmonics of the original bass fundamental to the output signal without the fundamental itself.

Gain [dB]:
There is a need to attenuate the signal because the method increases the output amplitude. Furthermore, it makes sense to place a Compressor and Limiter behind the Small Speaker Bass Enhancer.
