how does one share REW mdat files? "attach files" button won't take 'em.

[Zathrez]

I have a room acoustics problem, but I don't understand it enough to even be able to describe it well. So I guess I can at least give you the REW mdat files.

Except, I can't seem to find a way to post mdat files. The "attach files" button won't take 'em. How does one share REW mdat files on this ASR forum about room acoustics?

Newbies. What can you say?

Welcome to ASR!

The usually method is to put it in a ZIP archive and attach the ZIP file. Note that this site also has an attachment size limit (I think 5 MB, but not sure).

Got it, thanks!

For the lazy, I think you can just change the file extension to .txt, upload it to ASR, then tell people to change it back to .mdat after download.

Won't compress obviously, but saves a few clicks.

I am in a similar predicament with figuring out my REW plots. Are folks here so kind that they would give my plots a look and educate?

Sure. Just create a thread and upload the MDAT.

As a general note: having examined many MDAT's on ASR, here are some common mistakes:

1. Uploading too many measurements. If your MDAT won't fit in the 5MB limit, you are doing something wrong. I am not going to look at 30 measurements to find the one that I need. Often the first thing I do is delete all the irrelevant measurements and feel a pang of sympathy to Amir who has to pay the server fees.
2. Failure to properly label graphs.
3. Failure to ask a question. Tell us what your problem is, and take a measurement to show the problem. If you don't know what measurement to take, we can guide you.

That's amazing! I'm trying to get a good balance between absorbtion and refection. The room I inherited from the previous owner was completely padded on all the sides and had acoustic tiles on the ceiling (albeit glued on to the ceiling drywall). It was great for movies but too dead for stereo. REW rt60 measurement was less than 100. I built up some curved diffusers, added some headboard and other doodads to make the rear more lively. I like how it sounds now but REW still says my RT 60 is around 120. The other thing I want to figure out is if I have too much or too little bass traps.

Take a look at the link in my signature. Go to the section on RT60, there is a description there on how to take a RT60 measurement.

As for bass traps ... it's generally better to use DSP rather than bass traps.

Thanks for that link and all the work you put into this! The altruism of some folks simply amazes me. More stuff for my Notebook!
As for traps, I do like to listen to my records occasionally (despite the general consensus here that it is an inferior format) and like to keep the path analog. Analog Miles just sounds amazing. It may just be in my head, but then everything is.
