LP/HP filter (Input Filter & Output Filter)
Sound Processing2 bands of semi-parametric 2nd order high pass and low pass filters are available on each input channel and can be individually enabled and disabled. Frequency and Q-factor can be adjusted, and channels can be enabled individually. With cascading or combining the available filters, bandpass or 4th order high pass or low pass filters can be created.
Parameter Name | Parameter Range | Parameter Definition |
Show Table | Enable/Disable | Opens a table showing the filters that can be applied. |
Type | High Pass/Low pass | Opens a list of filters that can be selected. |
High Pass | Selection | With a High-Pass filter, the frequencies below the crossover frequency will be suppressed. |
Low Pass | Selection | With a Low-Pass filter, the frequencies above the crossover frequency will be suppressed. |
Frequency | 20Hz -20kHz | The Frequency parameter indicates the centre frequency of the filter. This is the central frequency between the upper and lower cutoff frequencies of the filter. The frequency can be set between 20Hz and 20kHz. |
Q-factor | 0.01 - 15 | The Q-factor parameter is the quality factor related to the bandwidth of the filter. A higher Q-factor indicates a more selective filter with a smaller bandwidth. The standard Q-factor value for the 7-band EQ is set to 0.9, whereby the 7 bands have good coverage over the entire audio spectrum. A higher Q-factor makes it possible to influence specific frequency ranges of the audio spectrum. |
Boost | Not Available | Boost is not available on the input filter. |
Enabled | Enable/Disable | Enables or disables the desired filter. |
