EQ Module questions

Hello,

I use REW extensively to measure the loudspeakers I build. Thanks for building such an amazing and great tool. It's used almost every day here.

Recently i spend more time working with the EQ module and it has saved me a great deal of time already.

When applying an x-over or some filters in the EQ window for a given measurement, one can turn on the 'predicted' curve of course. This really helps to model the desired curve. You can save the target curve as a measurement, which is great. It would be amazing if the predicted response can also be saved in to a measurement. If i do this for my woofer and tweeter separately, i can view them in the overlay screen to analyse the x-over point for example.

With this, REW becomes an even cooler tool to model my desired speaker-response. And now for the bonus question, would it be possible to create a combined response from two measurements?

Thanks!

Stefan

Great - that works well. Is it also possible to create a new measurement out of the predicted response in the EQ window?

Edit: Looks like it can be done by exporting the Impulse response as WAV from the EQ window and importing it again as a measurement, correct?

I have added an action to the filter tasks pane to generate a measurement directly from the predicted response, it will be in the next build.

Amazing!

Just downloaded the latest Beta with this function in it - this is GREAT! I can now do a lot of my filter simulation/modelling just based of an unfiltered woofer & tweeter measurement. This saves me a ton of time and even more important - provides hours of simulation fun!

Thanks John!

Just downloaded the latest version that now has the Linkwitz Transform as a filter option and loving it! This makes my workflow even easier!

I did notice that the paramters for the LWT filter get overwritten if you ask REW to match the target curve, where I would prefer for it to stay fixed with the values i gave it. My use case is to add an LWT and the desired x-over frequence to my measured unfiltered tweeter-curve and have REW smoothen out the curve. For some reason it always sets the LWT to 30 hz.

Is this by design, or does this need fixing?

Amazing work on another great release of REW!
