Relax with a calming mix of music and natural sounds. A special edition featuring the Sounds of the Earth mixes of music and the incredible sounds of the insects, birds and animals featured in BBC One's Wild Isles series.

The nature sounds were captured by the audio team at Silverback Films, with audio post-production from Wild Buffalo, and kindly shared with Radio 3’s Sunday Breakfast team for the weekly Sounds of the Earth feature.

Across Britain, 352 BBC transmitters stand, mostly on the tops of hills broadcasting sound, music and voices invisibly across the country. In this slow radio episode, Matthew Herbert and a group of recording engineers visited some of these transmitters in Scotland, Wales, Northern Ireland and England to listen to what the transmitters were hearing at exactly 11.30 at night - the time of this broadcast. Starting at the transmitter atop Crystal Palace and then moving through the country to finish in snowy Aberdeen, hear how the sonic landscape changes the further north travelled.

Transmitter is a production from Munck Studios with Matthew Herbert for BBC Radio 3, recorded by Pete Stollery, Hugh Jones, Dan Pollard, Ella Kay, Robbie McCammon, Pieter Dewulf and Cameron Naylor.

Relax with a calming mix of music and natural sounds. This springtime special features a blackbird singing at daybreak in Newcastle, a nightingale in the Umbrian foothills, central Italy, and a newly born lamb communicating for the very first time with its mother in a field in Wiltshire. Recordings by Radio 3 Breakfast listeners Sarah Couch, Nick and Val Bale, and Tom Perrett, plus master sound recordist Chris Watson.

This Slow Radio experience features sounds from the BBC television programme Wild Isles: a chance to revel in the extraordinary sounds recorded and created for the series, without voice-over or music.

Using an aural collage of clips, the half-hour soundscape takes a journey from mountain stream to the sea, around Great Britain and Ireland. It utilises sounds from the Freshwater and Oceans episodes and begins with a specially recorded introduction by Sir David Attenborough.

From there, the sounds of cascading streams and waterfalls give way to the call and shuffle of a common toad. Around the caves of County Cavan bats use sonar to navigate. Their ultrasonic clicks can be heard, slowed down. A cuckoo sings beside a chalk stream while a spider catches a pond skater in its web.

The distinctive low call of the bittern introduces the Suffolk reed beds, where great crested grebes perform a mating dance, beaks clashing. Further towards the sea, a colony of knot are scattered by a peregrine falcon, and in the Shetland Isles, a sea otter grunts and snorts around the rocks.

A thunderstorm at sea heralds a seal colony at Blakeney Point, Norfolk, where two males fight. Then the eerie calls of Manx shearwater, who visit each year from South America, are followed by the chatter of many gannets, in and out of water.

The Corryvreckan Whirlpool in Scotland pulls us under for an array of fantastical subaquatic sounds: cuttlefish, sea gooseberries, melon comb jelly; the squelch of a royal flush sea slug, spider crabs leaving their shells, and the scream of a scallop, devoured by a starfish. Dolphins break the surface, and a bluefin tuna skims across the waves before we sail out into Cardigan Bay.

Relax with a calming mix of music and natural sounds, from the Atlantic rainforests of Brazil to Eastern Banjo Frogs in Adelaide, Australia. Plus a dawn chorus in Cornwall and chaffinches in Noja, Northern Spain. Recordings by BBC Radio 3 Sunday Breakfast listeners Bob Castell, Kate Wilson, Peter Halmkin and Kevin Cox.

There’s a gentle rhythm to everyday life in a Hindu temple, that follows carefully choreographed rituals linked to the care of the deities - creating a rich aural texture from dawn when the gods are woken, to nightfall when they sleep. The sounds wax and wane; each part of the day has its own soundscape and the priest presides over it all. You’ll hear the constant sound of bells as a backdrop, rung by devotees as they approach the shrines, focussing their minds and alerting the deities to their presence.

The deities, or murtis, as they are known in Hinduism, represent the different aspects of God - in the form of beautifully carved statues. They are worshipped and cared for as the physical representations of God.

This episode of Slow Radio takes us to the Shree Sanatan Mandir, a Hindu temple in Leicester, where we recorded sounds from inside the temple across a whole Saturday. The mandir is one of the oldest and largest mainstream Hindu temples in Leicester, housed in a former Baptist chapel. There is one main ‘prayer hall’, home to 5 main shrines. But there are 17 shrines in all, representing the major Hindu deities including, amongst others, Krishna and his consort Radha; Ram and his wife Sita, his brother Laxman; as well as Hanuman, Ganesha, Shiva and Ambamata. In the wider temple building there are also other meeting rooms and halls.

During the recording you’ll hear worship across the day - singing and prayer, readings from sacred texts, meditation for the women’s group and quiet times for private devotion or chatting to the priest. You’ll also hear Illa Majithia and Anil Chauhan from the temple committee explaining some of the sounds.

But the programme starts with the sound of volunteers cleaning the temple at daybreak, as the priest opens the curtains around the shrines, waking the deities, before washing them, dressing them in fresh clothes and decorating them with garlands of fresh flowers brought by the devotees, who are gathering for early morning worship.

Relax with a calming mix of music and natural sounds, from birdsong and tortoises in the Seychelles to waves and whistling frogs in Barbados, via a bubbling brook in Northumberland and a murmuration of starlings playing in a poplar tree. Recordings by David Fay, Honey Schreker, Kathryn Potts and Rupert Ormond.

High in the mountains snow falls. As it comes to rest on the frozen slopes it become part of an ancient glacier. Over the course of 100 years the glacier will flow down the valley, changing the landscape around it.

Using field recordings from deep within glaciers, along with the sounds of the natural world around them, this programme charts an imagined journey of snow and glacier from mountain top to valley floor.

Over the course of that journey we hear the sound world change and the increasing impact of human activity on the landscape - the wilderness of the high slopes replaced by the noise of tourism and traffic. There is an irony to the fact that the people who choose to visit the mountains because they love them are also contributing to their changing environment.

These unique glacier recordings have been made by Ugo Nanni, researcher at the University of Oslo who specialises in the stability of Arctic glaciers, and field recordist Clovis Tisserand.

It is January 2022, and in the Upper Manhattan neighbourhood of Harlem all is quiet as people stay at home, preferring not to venture out into the minus-13-degree snow and ice that has blanketed the city.

This half-hour soundscape begins with the geese pecking at the frozen lake at the northern tip of Central Park with the occasional sound of a passer by who has braved the weather.

As we head north to Harlem, walking up Malcolm X Boulevard, an invitation into the warmth of the Abyssinian Baptist Church is welcome. It is no ordinary service but a celebration of Martin Luther King Jr and we hear sounds of the pastor and gospel choir as they join together in worship.

Heading back out into the bracing cold, Harlem is busier. More people are gathered on the streets with stereos playing music, and public transport still in operation, battling against the snow.

Sounds of live jazz emerge from local restaurants and wandering inside is a refuge from the weather, joining crowds of brunch-goers enjoying live music, drinks, food and the company of others.

It takes about half an hour to walk from Central Park to the Jackie Robinson Park, where a flight of swallows can be heard returning us to the sounds of nature that we heard at the beginning of our walk.

Relax with a calming mix of music and natural sounds: a walk in the Faroe Islands, a deer in the Scottish Highlands, a robin in Northamptonshire and a royal garden in Norway.
