If a tree falls in a forest...

 ...then you might hear it on this map...

It's called Sounds of the Forest.

We are collecting the sounds of woodlands and forests from all around the world, creating a growing soundmap bringing together aural tones and textures from the world’s woodlands.

The sounds form an open source library, to be used by anyone to listen to and create from. Selected artists will be responding to the sounds that are gathered, creating music, audio, artwork or something else incredible, to be presented at Timber Festival 2021. This second part of the project is gratefully supported by PRS for Music Foundation.
