The web MAP is very easy to use. The left window uses Google maps to show and locate the sounds on the map. If you click on the signs, you can consult, listen and download a sound recording made in that place.
By the way, if you wish to search for a specific sound you can use the search function, the categories also should be helpful for this task and finally you also can access to the sounds by families using post-inserted tags.
If you wish to participate, just click this link and follow the instructions. In a question of minutes the recording will show-up on the map.
The site works with most web browsers but we strongly recommend to use Google Chrome.
