Bathurst acoustic room treatment comparison (384kbps)

This video is a stereo recording of music playing in two rooms identical in dimensions, but one is treated. Credit goes to Earle Weston for the creation of this video. It was recorded with two Shure mics in the listening position. The video footage corresponds to the audio, so when you see it jump to the other room, that audio also jumps.

Bathurst 2012

It's that time of the year again - Bathurst 2012! I call it the audio event of the year, where a small group get together not far from the race track and play music much too loud, way too late, talk way too much, drink way too much and somewhere along the line find some time to do some nerd stuff ...

Bathurst 2011 >


This year we created a video to compare two identical rooms, one untreated and the other treated. The video will go online and instantly jump from one to the other. We measured the difference in room acoustics and set up the speakers in exactly the same spot. I don't know how well the experience will translate but I have to say the treated room was so much better, I can't imagine anyone would prefer the untreated version.

A couple of snap shots ...
