Hello,
I am trying to figure out the 'right' way to apply phase correction of a 2.1 system.
Some details on current pipeline:
> I use my PC as the hub for streaming & DSP. The signal outputs to a 2.1 system via a 6 channel soundcard where each if the channels may be controlled saparately.
> DSP is done via. EQAPO,
> DSP includes:
(a) Generation of LFE as sum of 0.5*(Rt+Lt), (b) Tuning of Lt, Rt, LFE, delay & gain (c) Bass management of Rt & Lt channel to LFE (XO80; LR4); (d) Remove room modes peaks of Lt+LFE and Rt+LFE. Using IIR filters (REW + nanual).
The outcome frequency response is good, yet not optimal from time (Impulse, Step characteristics) characteristics.
I thought to apply FIR to correct frequency and phase, but - as I am are dealing with a single Sub - it is not clear to on what combination should this be applied, my current 'options' include: (a) Lt+LFE, Rt+LFE, (b) Lt+Rt+LFE together (system), or (c) Lt, Rt, LFE saparately?
Any recommendations or exchange of experiences (good or bad) will be much appreciated!
