This audio object implements an N-channel point to point FIR filter with a constant number of taps for all
channels. This filter is optimal for higher order filters (> 1000).
Coefficients are provided through GTT custom panel from pre-stored coefficient files in .csv format.
- Coefficients can be different for each channel, but with same tap length.
- Coefficients represent the impulse response of the filter in time domain.
In the SFD, users can select the number of channels and the number of elements – taps. The number of input
channels is always equal to the number of output channels.
Without loaded coefficients, the filter functions as an all-pass filter passing the input signal as it is.
The AO supports in-place computation based on the core type.
Tuning:
- In the current init setup, the tuning filter coefficients consist of allpass/bypass. In the real world
setup, these will be replaced with actual filter coefficients calculated for the preferred vehicle
environment. - FastConv operational mode (Normal / Bypass / Mute) can be controlled (as tuning parameters) from GTT panel.
