'Digital' Room Correction

Everything Else

To store the room correction in the library.

I was puzzeling how to correct the room for a flat frequency response. This can be done passive (fysical room corrections) and active (analog or digital room corrections). Everything should start by measurements. With this data the room should be fysical corrected as far as possible or at least as far as reasonable. After this a new measurement must be done to calculate the active room corrections. Please correct me if I’m wrong!

The active room corrections can be done by expensive equipment, or by the build in equilyzer in Jriver for example. I'm confident that less is more for this approach. Let me explain! During the test period of the PWD it became very clear to me that software, must be stored on a Nass or computer in the format you play it. So if the dac play wav files you better feed it with wav files, don't let the equipment do the calculations on the fly. I think while data is calculated on the fly you get fluctuations in load. Think of this we have a few bites that have to be converted to wav doublewords 32bit, in this bites is not one bit true which is easy or the conversion.Then we have a few bites where several bits are true which is heavy for the conversion. I'm not sure if this is the reason, but it must be in the timing or load somehow. With the PWD it was also true while the computer did the calculations on the fly. There alway's was a derating audible. There was less derating while using two computers (more is morepulling-hair_gif) one computer did the calculations and the second computer fed the wav signal to the PWD. So worst case was when the PWD did the calculations, better while the computer did the calculations, even better when using two computers and the best way is when using the wav format that could be played immediately.

So with this information and the room corrections data it would be great to convert a copy of the music library and store the result on a harddrive so you have the best possible private library for your music room.

This way we will need less interconnects, less powercables in comparison with an active solution, less electronic’s less software and no data converted om the fly. Less is more!

I’m not sure if this software is already on the market, if else it should be made!
