Greetings friends,
I'm currently building my first DIY amplifier to run a 5.1 speaker setup directly from my PC.
I'd like to experiment with Digital Room Correction and see how far I can go with the current HW before upgrading or buying some serious, dedicated HiFi items...
The main objective is to automatically compensate for the different gain and
frequency response of the various speakers, the asymmetrical listening position/room structure and just try something new.
Can you recommend or point out simple SW tools and the minimal HW to enable real time DRC for 5.1 sound tracks under Win7 environment?
Would it even be feasible w/o a dedicated DAC/ADC , Quality Mic. and better sound card? (assuming I'm not going for "audiophile" results but more like "experimenting")
More details:
- Built in sound card is based on AD1986a / SoundMAX CODEC with 5.1 output signal and Line In/Mic ports.
- OS is Windows 7
- Player - currently based mainly on MPC-HC/VLC and SAF codec pack (FFDShow CODEC)
I saw this thread:
Free Digital Room Correction And PC based Xover
But I'm not sure if relevant for Movie based multichannel sound source.
Also this thread (was a bit over my head😕):
Digital Room Correction Project
Which seem to use a much better dedicated HW and SW tools + based on Linux and I'm not sure regarding multi channel sound tracks...
Thank you in advance - A GREAT forum indeed!

Hello again,
So - I pretty much figured out the SW part of this project (still a work in progress but I've got the initial direction) which consists of basically 1) calibrating the Sound-card In/Out, 2) record the room/speaker response for each channel 3) analyze responce and create a FIR file for each channel 4) use this file for the convolver filter inside my Audio decoders (FFDShow mainly).
I still haven't decide on a suitable "recording" HW = Microphone to fit my needs and budget...
On one side there are this simple PC Mic's used for Skype etc... they are cheap, connected directly to the MicIn terminal - but I suspect their quality is too low even to my humble requirements...
On the other side there are "professional" measurement Mic's like the recommended Behringer ECM8000 - not too expensive but require additional HW (pre-amp and PSU) before I can connect it to the Sound card and I'm pretty sure I'll lose most of it's qualities through my entry level ssetup...
Any other suggestions?
A cheaper "all-in-one" solution for PC calibration?
Maybe a DIY setup based on cheap Mic Capsules (Panasonic etc...) - any guide on how to connect these to an unbalanced MicIn/LineIn sound card?
Thank you,
Gal

Apparently the ADI AD1986a does have some kind of preamp for the Mic and LineIn signals -
would it make it easier to connect some kind of Capsule or Behringer ECM8000 directly to it ? (w/o a dedicated preamp) ?
Here are some specifications taken from this document:
