Wishlist for next REW upgrade...

**Sonnie** · **01-26-07, 01:23 AM**

We may as well go ahead and start a wishlist thread for the next REW upgrade.

Post your suggestions in this thread please! Thanks!

**daxie** · **01-26-07, 01:58 AM**

My request for total newbies:

* Step-by-step wizard interface...just connecting cables, clicking next, you know.
1) Setup soundcard
2) Calibrate soundcard
3) Setup SPL-meter
4) Calibrate SPL-meter
5) Other settings
6) Make first measurement

something like that.

I have a couple. Not critical but desirable I think and certainly not meant as criticisms.

Keeping the target cut-off and meter cal curves visible after "all measured" button is pressed. It would aid comparisons between the curves rather than judging by eye.

More trial curves saved beyond the present 9. There seems to be lots of room in the left margin for at least twice as many. REW is so quick to use that many trials are easily possible in half an hour of trying BFD filters. I found myself repeatedly deleting valid trials and quickly lost sight of my first filter trials. So I was unable to monitor actual progress rather than follow hunches.

That said, these curves could have been saved as Jpegs or .mdat files if I really wanted them.

I consider 4.0 a considerable advance on 3.29. Thankyou John and friends.

The only thing I can't seem to find is the following:

The ability to combine a calculated sub response with a measured speaker response to help with estimating their combined response. This may help when working with filters to make sure the crossover point isn't affected.

I like the idea of a wizard for initial setup too. Maybe help make it idiot proof by adding a simple setup diagram. (Soundcard-->receiver mic-->line-in)

The only other thing I can think of is if there was a way to "simulate" the filters by altering a signal going out to a receiver.

That's relatively straightforward for the test signal, which then allows measuring the effects of filters without having to download them to a BFD (or even have a BFD). It will be part of the process of optimising the filter settings through multiple passes of measuring, applying filters, re-measuring etc. Needs some thought on how the UI for that works though. One of the (many) things on the dev list. Stay tuned

Yeah, I thought that a rather smart suggestion by niget2002. It was right in line with the standard troubles lovingdvd was having with the remeasuring conundrum. It would be a great feature to have since you wouldn't need to enter your filters every time. You could just keep sweeping with a filtered signal until you liked the result. Then you would know that once you put in the filters to the BFD, it would be correct the first time......

Yes, exactly. In fact I posted about this earlier today here: http://www.hometheatershack.com/foru...remeasure.html

So am I correct to assume that the way things work now you get one crack at it and once you measure you can't remeasure based on the last results, but rather you have to keep going back to the original mdat with the filters?

Man, this new simulated results feature would provide a HUGE leap forward in terms of ease of use and speed up the process greatly.

Right now its very tedious and time consuming to keep entering everything into the BFD manually. Will be better once my 1.4 chip comes so I can use MIDI, but the simulation will be fantastic. Funny thing is what I consider tedious must be light years better than how things were before REW and all this had to be manually calculated!!

**lovingdvd** · **01-26-07, 03:17 PM**

One feature I'd like to see is to have an option to have REW recommend or at least work with positive gains to fill gaps, at least smaller ones. I know adding gain is generally considered a no-no, but in some cases it makes sense.

brucek - I know you probably thought I was crazy the other day when I said that REW kept deleting my AUTO filters when I added them and told it to optimize... I figured out it was because these filters were for +dB (gains).

So my feature request is to have REW work with +dB gain filters that I add in as AUTO and take them into consideration when optimizing (even if it doesn't recommend any itself automatically). Thanks.

Not really.... reduces dynamic range and signal to noise ratio. You want gain, turn up the sub....

**Ivaols** · **01-27-07, 04:01 PM**

A direct print button in the filter window. That way i dont`t have to wright freq/BW/gain down before punching them into the Behringer.
Maybe there`s a better way than wright them down (?), but i haven`t figured that out. It`s a lot of numbers for a newbie who ads 17 filters...

**Wayne A. Pflughaupt** · **01-27-07, 05:47 PM**

Poor John! The ink isn’t even dry on the latest version, and here we are bugging him for more!

I too would like to see a “quick set up” like many receiver manuals have these days, without all the “These steps are required because…” and so forth.

Also, maybe the program could default to a quick step-through after all the initial set-up is accomplished, which would show up each time the program was opened.

I’d like to see the graphs calibrated in increments of either 2 or 5 dB, not 8 dB!

Regards,
Wayne

It would help speed thing up if you could delete a measurement set (1 out of the 9 on the left of the screen) just by clicking on it to select it and pressing the delete key, and then saying Yes to the "Are you sure?" message.

Likewise it would be great if you could do a alt-click or shift-click to select multiple measurements and hit the delete key to delete a group at one. Often times I have a full set of 9 and want to get rid of much of them, so it can be a bit tedious to select each one individually, right click, choose Delete, say Yes to confirm, and then repeat 6 or 7 more times.

No a big deal, but just a suggestion for helping improve usability a bit. Thanks.

**Peter De Smidt** · **01-27-07, 07:18 PM**

Can REQW output frd files for use in a program such as The Frequency Allocator? See: http://www.thuneau.com/allocator.htm If not, that'd be nice!

File / Export / Filters Settings as Text

This sends the filters to a file - print it...

Do you have Word? Actually you can even use Paint, which comes standard on all PC's. Hold down the WinKey (windows flag key) or on some computers it may be the Fn Key... and press the PrtSc key once. This places a copy of the screen on your invisible clipboard. Open Paint or Word, right click and Paste OR Edit/Paste. Then print.

Right click any graph on the left hand side and select Delete... does exactly what you are wanting.

**lovingdvd** · **01-28-07, 12:21 AM**

Another feature request would be to automatically carry the currently selected Target type (Bass Limited, Full Range, Sub) onto the next measurement. For instance tonight I was taking measurement after measurement after measurement as I dialed things in. After each one I had to keep switching the target to Full Range. Thanks.

The feature is already there.

Also, ALT + PrntScr will copy the current active application window in case you have lots of open progs at the same time.

Is there a way to have REW automatically apply the 1/3 octave smoothing options to each measurement, so that I do not have to repeatedly choose this after each measurement as I do now? If not please add this to the wish list.

Ctrl+Shift+3 is a quick way to apply 1/3 octave smoothing, and Ctrl+Shift+0 to remove it. Don't use smoothing on low frequency measurements though, filters optimised against a smoothed response will have settings that don't accurately match the room's modes.

Oops. This is how I did my entire curve. Seemed like it just smoothed things over. I'll pull it back up and remove the smoothing to see what it looked like. Then again the sub sounds fantastic as it is, so maybe its just slightly wrong but "right enough"!

**brucek** · **01-30-07, 04:48 PM**

We usually recommend to only use the smoothing when you're all done and want to see how it looks with smoothing to more closely approximate how you might hear it. I always ask everyone to post the raw information, so I don't make errors in any suggestions I might have. The smoothed plot is for your eyes only.....

I've been using the latest version for a couple of days in my latest assay on EQ'ing, and it may be me not knowing all of the nuances but I'd like to see the following:

I've tended to run a whole series of sweeps for a specific setting, say 80Hz crossover. e.g. Phases 0, 90 and 180. And then a sweep of the mains on their own and sub on its own. I save all the data to a single file. I then clear the data and start on a 60Hz crossover and do the same. As I don't know what I'd like to compare to what after all the readings are done, it would be helpful if one could load a measurement form a file that say had 9 data sets, but be able to nominate which individual set I wanted to load. Much easier than having to individually save single measurements on the off chance I may need them. So then it would be easy to say load in all the "Mains Only" data sets from each of the main mdat files. Do I make any sense on this?!!

Also if loading a "single" data set mdat into a current data series with 9 sets already defined, then the new loading should overwrite the currently selected data set, rather than the oldest and a prompt to delete it or cancel. I may want to keep the first series in the current project and only replace the 8th one, so to having to cancel on 6 more prompts is not the most efficient way and loading a data set file into an existing set.

Is there any way to be able to tag a note or name each of the 9 data sets so that the graphs become more meaningful. I found I was having to write down a summary of what each sweep/response related to. So to be able to name #1 "Mains Only 80Hz XO" would be a help for me.

When having worked on a number of data sets in the current project and I need to start with a clean slate for my next run, it would be more intuitive to have "File, New" as a way to start a new project instead of Delete all Data. I get an uneasy feeling that deleting all data and an accidental save "all measurements" will overwrite my old file.

In the window title have the name of the current loaded file (if already saved) with an '*' if any changes have taken place without a save, or 'New' if no save has taken place. I was loading up a number of data sets to compare and it would have helped if there was a reminder on the screen as to what file I was currently working on.

As I am still working my way through this there may be other things I come across which may make it easier to deal with data across multiple sets.

Good work though John! Excellent!

EDIT
... and in addition to being able to name the 9 data sets, have the ability to drag each one up and down the list to change its sequence.
