4. Digital Room Correction
This is the last part of the setup and a relative easy part. There is a macro for it and for those who do not understand DRC, you can google for it as there are lots of information available already. Basically, you need to measure the sound produce by your speaker and measure that at your usual listerning position. What you measured include the sound from the speaker as well as the room response. The computer can now generate a filter that compensate for the difference. What different from EQ is that this works in both time and frequency domain.
In the above picture, you will notice that the red line is the room response and the green line is the filter.

Hi,
have you really been able to do all those things that Accourate is, at least in paper, capable of?
Can you really hear a difference?
Is room correction better than acoustic room treatment?
Does the sound from your speakers improve with all the Accourate tricks?
Have you ever considered trying the Audiolense? It is somewhat less technical and easier to use ... but maybe not as mature as Accourate.
Both are crippleware i.e. as tryout SW they don't allow you to create the correction filters at all.

Dear Esa,
yes. i did all this with Acourate and the difference is impressive. i have not tried room acoustic treatment because of cosmetic reasons! cannot get my wife's consent! with Acourate, i can do digital crossover as well. i have not tried audiolense so i cannot really comment. but i know Uli since my previous experience with TACT and i know the quality of his filter. i bought the licence so i can generate the filters!
