Help one: japa Its a frequency analyzer and can output white and pink noise. It can help you set your EQ correctly.

To really flatten and optimize the room-response electronically you will have to record the impulse response of your room (for each speaker) and use drc to compute a correction function in time and frequency domain. Then you can use that pulses with jconvolver to get a better room. I do that at my home and its really great, even though my speakers already where great. Here is a catch: with digital room correction you will have to undo some of your room optimizations. But the details are in the very good drc-manual. > 2: How do I emulate "the perfect" studio and other situations with > the help of Jconv? Once your room is optimized, you can use any additional impulse response to put your room into another acoustical environment... Have fun, Arnold
