Over the past decade, Social Broadcasts has been combining community led co-creation, participatory art practice and radio making, to produce place-based audio projects all across the UK. In 2021, sonic storytelling platform XMTR.FM was launched with the ambition to showcase work from both emerging and seasoned independent audio makers from across the globe. 

XMTR AUDIO ARTS FESTIVAL combines these two concepts to imagine an audio festival that champions local stories and artists, as well as showcasing audio works from around the world. Established in 2024, XMTR is delighted to be back for a second year of the festival. 

XMTR has joined forces with the Sono-Electro sound arts festival, taking place 16th-28th September at Electro Studios.

Join the creative audio community from Friday 26th to Sunday 28th September 2025, for 3 days of sound installations, performances, listening events, workshops and sound walks, to celebrate sonic storytelling at venues and spaces in and around St-Leonards-on-Sea.

Unit 2 will be the festival hub, with installations and workshops happening throughout the weekend. There are some free open to all and family events throughout the festival, just check out the programme for details.
