Matmos spent a week at Chalkwell Hall in June 2015, sampling and recording the sounds of the people, the park and environs.
The key instruction is 'Listen, then drift' inside Chalkwell Park, Southend-on-Sea. As you wander you will encounter a series of eight tracks including the instructions. This app is best experienced with headphones.
Use the map to navigate towards each GPS zone and the track will automatically play. Switch GPS on before starting.
If you are unable to visit Chalkwell Park in Southend-on-Sea then click on 'MP3' to play the tracks wherever you are.
Approximate listening time: 30 minutes.
