Originally, EQ10Q was just an equalization plugin. Now the project has grown and some other plugins has been included but the project name has remained unalterated. Here it is the complete plugin list:
EQ10QM / EQ10QS
10-Bands parametric equalizer with mono (M) and stereo (S) versions.
There are gain, frequency and Q controls for every band. These controls can be operated using the mouse, the keyboard (double click to introduce a numeric value) or interacting directly with the ploted curve (drag and drop or mouse scroll wheel). It is possible to enable/disable a band to listen the effects on equalization or perform full settings comparisons with A/B buttons. It also features input and output gain controls and VU-meters.
Each band can be configured independently with the desired filter type. The available options are:
Low Pass Filter with 6 dB/oct roll-off
Low Pass Filter with 12 dB/oct roll-off
Low Pass Filter with 18 dB/oct roll-off
Low Pass Filter with 24 dB/oct roll-off
High Pass Filter with 6 dB/oct roll-off
High Pass Filter with 12 dB/oct roll-off
High Pass Filter with 18 dB/oct roll-off
High Pass Filter with 24 dB/oct roll-off
Low Shelving Filter
High Shelving Filter
The internal audio processing is completely done using 64 bits floating point maths and the peak filters uses a special algorithm designed to emulate the response of an analog equalizer yet keeping a low DSP usage (read more about this).
EQ1QM / EQ1QS
Exactly the same as EQ10QM / EQ10QS but with just one band.
EQ4QM / EQ4QS
Exactly the same as EQ10QM / EQ10QS but with 4 independent bands.
EQ6QM / EQ6QS
Exactly the same as EQ10QM / EQ10QS but with 6 independent bands.
*Please be aware that using an EQ10Q version of a lot of bands demands more DSP load than a few bands version. This is the reason of the existence of versions with different band count. So, in large projects with a lot of EQ10Q instances, is a good practice to try to use the versions of EQ10Q with fewer bands when possible to minimize the overall DSP load.
GT10QM / GT10QS
Versatile noise-gate plugin with mono (M) and stereo (S) versions.
This plugin provides the usual controls in a dynamic gate processor: threshold, range, attack, release and hold. But also features some extra parameters to allow an accurate adjustment. The gain control is useful to bring the input sound level in the correct VU meter range to be able to tune the threshold right. Even though the internal processing is performed in floating point at 32 bits, it’s helpful to adjust the input gain in a standard range to achieve an optimum level visualization. Together with VU meter, there is also a gain reduction meter that aids to set up the controls.
Besides the power of dynamic section controls (DYN), there is also a filtered side chain section (SC). Here it is possible to adjust a low pass filter (LPF) and a high pass filter (HPF) and listen the actual side chain signal after filtering with the “Key” button. This side chain flexibility is very interesting to avoid unwanted noises to start triggering the gate.
CS10QM / CS10QS
Compressor plugin with mono (M) and stereo (S) versions.
The controls of this one are very similar to the GT10Q control because the DSP code have a lot in common. The main difference is in knee control which sets the smoothness of the compression around the threshold point.
In the compressor, the side chain filters can be useful to avoid excessive compression triggered by some specific frequencies.
This plugin is aimed to enhance the bass guitar sound or other low frequency sounding instruments.
The processing is based on a psycho-acoustic effect that is used sometime on some small portable music players to improve the human perceived bass response. This principle consists in generating some harmonics of the fundamental tone. When the fundamental harmonic is below approximately 100 Hz and a harmonic is synthetically generated, human brains tends to merge these extra harmonics with the original sound raising the feel of a deeper and more powerful sounding in the low frequency range. But without overloading your mix neither your speakers because actually there isn’t any increment of very low frequencies (just some extra harmonics). The only knob controls the amount of generated harmonic. Play a bit with that control to get the position that fits best in your mix, I’m sure that some harmonic level will result pleasing to your ears.
This plugins implements a part of a mid/side matrix. It converts a stereo signal encoded in L/R mode (left-right) into a stereo signal encoded in M/S mode (mid-side). Using this plugin is possible to use other plugins or outboard hardware as mid-side processors. The mid-side technique is capable of enhancing stereo signals by treating in a different manner the central part of stereo image than the laterals. The gain controls are specially useful if outboard hardware must be used. Some signals might present a low levels in side or mid channels. In such cases the gain controls helps to raise those levels to take profit of all bits in your digital to analog converters (DAC).
After performing some mid/side processing in a stereo track it is necessary to restore the original stereo codification. This plugin will be placed at the end of a Mid/side processing chain in order to obtain a L/R signal. The provided gain controls adjusts the level of each signal. This gain controls are useful to restore the original levels if some extra gain or attenuation is used previously in LR2MS plugin to compensate DAC/ADC converters.
