Halogen 5.0’s FIR Filter Import DSP Block

FIR chainHalogen 5.0’s FIR Import DSP block is available to all four current HAL models.*  The FIR block permits importing finite impulse response (FIR) filter coefficients. To obtain the FIR coefficient’s file, either:

1) Download the applicable FIR file for the loudspeaker from the manufacture’s website – e.g., Fulcrum Acoustics, or

2) Generate the FIR coefficients from measured loudspeaker response data using the software packages that create FIR filters manually:
