This simulator serves to get you acquainted with Mozzaik1's control panel. The algorithms behind this simulator are a very rough example of how the physical product performs and can in no way replicate the effect of a live listening experience. The simulator's purpose is purely educational.
The settings are arranged into two rows with the names of the settings from left to right as follows: compensation frequency, speaker compensation and psychoacoustic characteristics.
There are two controls in each setting group. The top ones increase/decrease the setting value in bigger intervals while the bottom ones do it in smaller intervals. The top bigger intervals have states from 0 to 6 and the bottom smaller intervals have states from 0 to 11. Think of it as coarse and fine controls.
Compensation Frequency and Speaker Compensation settings work together to reduce speaker distortion.
To compensate for the distortion in speakers we first need to set the compensation frequency. This frequency is very closely related to the crossover frequency of your tweeter (the high-frequency speaker). Once you know the crossover frequency of your tweeter the next step is to adjust the setting to a value that is as close as possible to the respective crossover frequency. The simulator will help you with this by displaying the current frequency value underneath the setting controls.
Once compensation frequency is set it is time to reduce distortion at that frequency using the speaker compensation setting. The general rule of thumb for this setting is to have the value higher on high efficiency speakers and vice versa.
The way it works is by adding additional distortion to the already existing speaker distortion. Increasing the setting value increases the amount of distortion you are applying. The idea is that with two negatives (speaker distortion and electronically produced distortion) we essentially nullify the original speaker distortion.
Every sound system is different so the best way to adjust speaker compensation is by listening.
The simulator algorithm is set up as if the speakers had a crossover frequency of 2553 Hz and that the speaker compensation setting was optimal at -50.5 dB. That means if you set the compensation frequency to 5 on the coarse knob and speaker compensation to 3 on the coarse knob you will have nullified the distortion of simulated speakers.
with both controls in starting position the frequency is 55 Hz
speaker crossover frequency can usually be found in the speaker specifications document
This setting is all about how you, as an individual, perceive sound. The first two settings adjust the objective, physical characteristics of sound, whereas psychoacoustic characteristics adjusts the subjective, personal perception of sound.
At the electronics level this setting adds distortion in a similar way that the speaker compensation setting does. The difference is that the distortion in use here is much more complex than the one for speaker compensation and it is a product of extensive research into how the human ear perceives sound. There is no general rule for this one, when it sounds good, you're done.
NOTE (does not apply to the physical product):
It is recommended you keep the volume constant when adjusting the values. If you have found the psychoacoustic values that sound good then those values will work for that specific volume. Changing the volume may require different values for psychoacoustic characteristics.
On the left-hand side is the playlist. It is comprised of short sound samples that run on repeat. Underneath the playlist is the volume control. We suggest you keep the volume constant when you adjust the settings.
On the right-hand side is the control panel with the settings arranged as on the physical device.
If you are using a desktop computer then adjusting the settings works by left-clicking to increase and right-clicking to decrease the value.
Left-click on the control to increase the value of the setting
Right-click on the control to decrease the value of the setting
If you are using a mobile device or tablet then swipe the control knob to the right to increase or swipe left to decrease the value.
