Just a fun project to watch construction progress across the street.
I'm on the neighbourhood panel that meets with Metro Vancouver, monthly, to annouce upcoming work, and to air out any neighbourhood complaints. Most of those have been about upcoming traffic worries - when the endless parade of trucks begins the hauling to/fro the Big Hole - and about noise that's already been a trial.
This isn't about that. Metro has their own sound monitors, and regulators to deal with. If we have neighbourhood complaints, they don't come down to exact decibels or anything. It's just a computer project. I hope to tell the Calgary Unix Users Group about use of Unix and Free Software for webcams and audio analysis.
The audio isn't up on the main page, and won't be. It's 10MB per hour for the 60 images (1 every minute) and another 10MB for the MP3 of the hour of sound. Not much point in listening to it! The valuable thing is to load the MP3 file into "audacity", the free sound editor, which can make the hour into a graph of sound loudness.
This sound graph is for 2025, September 29, 9AM-10AM, at the site. I've marked it up a bit, to show when the Vacuum Excavator was running, or revving its motor. And how the loudest sounds around here are still the big, I think medical, helicopters that run from YVR to Coal Harbour, right overhead.
I did it on my keen new 4K screen, so it's very wide. I rotated it so it's sideways; you can scroll down.
An example "GIF Movie" of one hour of sixty webcam snaps, each minute, is below. It's 31MB, so below is the first image; click on it to jump to the movie file.
