Sound maps are in many ways the most effective auditory archive of an environment, touching on aspects political, artistic, cultural, historical, and technological.

The Montreal Sound Map is ready for submissions. We are accepting all (unprocessed) audio recordings (past and present) of Montreal’s sound environments. Our goal is to gather and display as many recordings as possible from all over the island. As we gather submissions, we will be placing them into a browseable tagging system based on criteria
including:

Sound Source (specific, characteristics)
Location (borough, neighbourhood, municipality)
Date (time of day, month, day of week, year, season)
Environment Type (park, metro, indoors, outdoors, etc…)
Equipment (recording device, microphone, etc…)

Files can be uploaded through the form on the website.
