FIR Designer M : Channels – Gain, Polarity, Delay
Channel gain, polarity and delay can be set on this view.
The channel gain corresponds to the channel gain to be used in the speaker processor. This is also shown on the System Export tab.
The channel delay here is used to time or phase align the channel with other channels however, depending on the FIR filter delays used in each channel, it may not exactly correspond to the delay to used in the speaker processor. The System Export tab shows the Total Processor Delay for each channel, including any adjustments for the relative FIR filter delays.
The channel Flip polarity setting is also shown on the System Export tab.
This plot shows the magnitude and phase for all channels with gain/polarity/delay applied and for the combined system response. The channel target response is also shown.
