Drawing the target curve clearly changes the sound and this can be heard and confirmed with REW when I measure the effect... Of course there are limits to this since not every suck-out can/should be corrected by the DSP. > > You can export the impulse response to a WAV file.

I looked around earlier this year and could not find Windows binaries before upgrading to JRiver 20. The nice thing with JRiver 20 is that the DSP processing can now be applied to DLNA/UPnP libraries before streaming out. This allows my server computer which has a decently powerful CPU to do all the processing to whatever device I have with the power of the JRiver UI to get the upsampling and DSP chain the way I like. I just have to get the room response, load it up on the server with JRiver running, and away it goes for streaming to whatever DLNA device I have... Note though that I really still HATE DLNA/UPNP since I feel LMS is so much better, faster, more flexible... If someone could build a good DSP engine into it (alas Inguz is too unreliable for me and seems abandoned?), there could be lots of fun to be had! > > In REW all you can do automatically is averaging multiple measurements. > I wonder if there is a better way of solving that problem automatically? > Optimise with respect to what?

They do seem pricy: Acourate 286 Euro for non-EU country, Dirac $500CAD stereo & $900CAD multichannel, AudioLense at least 165 Euro for basic version to 390 Euro for the XO version. Would be great if someone could compare/contrast and provide an opinion!
