Thanks for everyone's participation in the study! We were published at the 133rd AES Convention. Here's a link to our poster, and here's our paper.

The Reverb Study

Conducted by Mike and Kyle

REVISED!! Mike made a boo-boo, and is trying to fix it. THIS IS A DIFFERENT TEST THAN THE ONE ON TUESDAY!!!

Thank you for participating in our study! It means a lot to us. We don't have much to offer in way of thanks, but if you'd like we offer amazing chair massages. All you have to do is participate in the study for us! If you're interested in helping us (or just a free massage), read on!

The goal of this study is to generate a reverb that sounds as natural as possible. Not an audio buff? Don't know what the word "reverb" means? Used to know but forgot? We've got you covered. Reverb is a combination of reflections in a room that create a "room sound." Each room has its own unique "sound" to it because of the way it's built. A concert hall has a longer reverb because it is a very large room, and there usually aren't a lot of absorptive materials such as carpets in the hall. Your bedroom has a much shorter reverb because it is a smaller space and has lots of absorptive materials, like a rug, blankets, pillows, etc.

At this point you might be thinking "okay, cool. Reverb sounds easy. What do you need from me?" We've made a reverb that we think mimics actual rooms quite nicely. In the examples below, you'll be presented with four different audio files. The first is a recording of an audio file being played in a room. The following three are synthetically created audio files, each trying to mimic the actual room sound. Your job is to rank each of these three files in order of most-to-least similar to the original file. There are three different examples in all.

Detailed Instructions

Click here to open the rating form
For each of the three boxes below, listen to the first sample, labeled: "Control".
Then, listen to each of the following four samples, labeled A, B and C.
Using the rating form, rate each sample from 1-3, 1 being the most similar and 3 being the least similar. You may only use each number once per box.
When you are done, enter your name on the form and hit submit. Your results will be emailed to us!
IMPORTANT NOTE: The audio files are uncompressed. What's that mean? It might take a few seconds before the audio plays after you click a link. Please be patient :)
IF YOU DON'T LIKE THE LAYOUT: I'm sorry. This is the best I could do. I recommend pulling the rating form into a separate window (not a tab) and placing both windows side-by-side to make things easier.
