The “Comunale - Pavarotti” Theatre (Modena -Italy) was recorded by Enrico Armelloni and Adriano Farina as part of the  Sipario project.  Impulse Responses were recorded by the 32 microphones of the Eigenmike, (A-format), next converted from A-to-B format using Gary Elko's (MH Acoustics) plugin encoder, they are "3rd order" and lastly converted to "1st order".

Hidden away and mysterious, with beautiful reverb.  We positioned the microphone marked with a red dot in the chamber past the Second Chamber.  As you can see on the survey, the cave continues much deeper.  After this ‘third’ chamber, the tunnel gets very narrow and tricky to move with equipment. In this schematic, the microphone (M1) is indicated in red and source positions (S-2 - S7) are indicated in green. The current listening order corresponds to the round thumbnail images from left to right: S1; S2; S4; S7.

A large part of the Ingleborough Cave system that we worked in was actually an underwater river, the whole 500m stretch is visually exhilarating. As one walks down the curving tunnel the last 100m of the area accessible to the public sounds the most enticing. This is the area named 'Long Gallery, '2nd Bells', 'Skittle Alley' and 'Pool of Reflections'. The play of light, darkness, echo, reflections, shapes and sound is mesmerising.  The connected underground otherworldly network of tunnels, halls and passageways has a tranquility and magical atmosphere, far away from our everyday reality and immerse the senses completely.

Thanks to Mariana Lopez for operating the Sound Devices and Richard Carter for aerial photography and additional photography. Thanks to Andrew Jarman, Ingleborough Cave management, for their support and for giving us access to take measurements in this amazing underground cave.

Ionion Mirror (part 1): This location in the sea was a tragic site where refugees drowned. A performance video/sound piece was created from this exact point in the water with sounds and video from above and under water (Cobi van Tonder). The acoustics are currently presented as an impression rather than via the standard impulse response methods of taking acoustic measurements. Sing into this space to hear the resonances from the drone music. A short distance from this point is a tiny little island called Zeus, seen in the reflection of the mirror.  Thanks to Ionion Art Centre.

The Tvísöngur Sound Sculpture designed by German artist Lukas Kuhne is situated in the mountains above Seydisfjordur, northeast Iceland. This mushroom-looking concrete sculpture consists of interconnected domes in different sizes. Each one of the domes has a resonance that corresponds to a tone in the Icelandic musical tradition of five-tone harmony and it serves as Helmholtz resonators, as the wind blowing in off the cliffs rushes into and across the openings, the air within the structure resonates.

Melissani Cave is located on the island of Kefalonia, in the Ionian Sea. In Greek mythology, Melissani was the Cave of the Nymphs. It features a lake surrounded with trees and forest, and is located east of the mountains of Evmorfia and Agia Dynati. The Ionion Art Centre, Kefalonia is making work here possible. The RIR here is imaginary/artistic - no actual measurements were conducted (as of yet) - as this project has been delayed due to travel restrictions. The reverb was extracted from cutting off the tails of other recordings made on a boatride in Mellisani and edited together to form an impression.

The Cathedral Church of St Peter and St Wilfrid, known as Ripon Cathedral, and until 1836 known as Ripon Minster, is a cathedral in the North Yorkshire city of Ripon. Founded as a monastery by Scottish monks in the 660s, it was refounded as a Benedictine monastery by St Wilfrid in 672. The present church is the fourth, and was built between the 13th and 16th centuries. The cathedral is notable architecturally for its gothic west front in the Early English style, as well as the Geometric east window.

Set in a bay at the foot of high chalk cliffs this sand and pebble beach stretches for around 1.2km. Many rockpools, at low tide and hardly any beach at high tide.  Sea lions, gannets, oyster-catchers, gulls and eider ducks can all be found here. There has been a lighthouse near this spot since the 17th century.  The current structure, built in 1806, still guides vessels safely around the rocky headland.

The Taj Mahal is an ivory-white marble mausoleum on the right bank of the river Yamuna in the Indian city of Agra. It was commissioned in 1632 by the Mughal emperor Shah Jahan (r. 1628–1658) to house the tomb of his favourite wife, Mumtaz Mahal; it also houses the tomb of Shah Jahan himself. 

The Taj Mahal complex is believed to have been completed in its entirety in 1653 at a cost estimated at the time to be around 32 million rupees, which in 2020 would be approximately 70 billion rupees (about U.S. $1 billion). The construction project employed some 20,000 artisans under the guidance of a board of architects led by the court architect to the emperor, Ustad Ahmad Lahauri.

The Taj Mahal was designated as a UNESCO World Heritage Site in 1983 for being "the jewel of Muslim art in India and one of the universally admired masterpieces of the world's heritage". It is regarded by many as the best example of Mughal architecture and a symbol of India's rich history. (Wikipedia)

“The Cumaean Sibyl cave is a mythological place in the north of Naples, where the Sibyl, a priestess presiding over the Apollonian oracle, received the travelers and predicted their future. The cave is length about 140 m, with trapezoidal section excavated in the rock of tuff. The cave has a height of about 4.5 m and it is 2.4 m wide. The legend says that the Sibyl received the travelers in the final part of the cave. Acoustic measurements were done with an omnidirectional sound source in the in the room inside the Sybil cave while positioning the microphones along the cave.” Prof Gino Iannace & Umberto Berardi

“According to the legend, witches were women with magical knowledge that with the use of herbs cured illnesses and performed spells. In 1639, the book “De Nuce Maga Beneventana” described how the place where the “witches” gathered was an area south of the city of Benevento in South Italy in a long and narrow gorge. This valley with high rock walls was called the “stretto di Barba”. According to the legend, under a walnut tree in the “stretto di Barba”, the Longobards were used to perform sacred rituals. To make the rituals more effective, the sounds were amplified by the narrow gorge with flat and parallel rock walls”. Researched and recorded by Gino Iannace, Umberto Berardi, and Amelia Trematerra.

Waenhuiskrans Cave is a limestone cave, within the Waenhuiskrans Nature Reserve on the South African Cape coast. Due to ocean water sound levels inside the cave, this site does not have an impulse recording, only some ambient sounds to listen to.

York Cathedral was built between the 12th and 15th centuries on the foundations of the previous Norman church that was in turn constructed on the foundations of the original Roman fortress.

Its dimensions are approximately 27m high to the vaulted ceiling, 160m long and 76m wide.

It is constructed mostly of stone with extensive, large panels of stained glass windows.
