Our reader Gautam Pemmaraju, who is also columnist at the great 3quarksdaily blog, has pointed me to a great post he published some months ago, dedicated to explore reverb and echo effects from a mysterious and interesting approach.
The whispering gallery that runs along the inner periphery of the dome of Gol Gumbaz, the mausoleum of the medieval Bijapur sultan Muhammad Adil Shah (1626 – 56 CE) is an acoustic marvel. Multiple echoes of up to ten in number can be heard in the dome on a single clap. And a reasonably soft whisper can be heard across a distance of a hundred and thirty feet. The tourists visiting the place are mostly prone to whoop, shout, and clap with great enthusiasm, overwhelming the dome with dense sonic information. At quiet times though one can savour its rich, amplified reverberance—the timbre, colour and tone of the spoken word assumes an elevated quality, as if it were imbued by the sheen of something beyond earthly artifice.
Such sonic modulations appear to us to be of a higher order, sanctified by primordial forces. And in our own mimetic appropriations, of sermons and speeches, chants and songs, drones and dirges, we seek to texturize our words with an otherworldly aura. The use of delay effects in sound recording allows us then to ritualistically edify our anxieties and inadequacies and transpose them into reverberant solemnity.
The prosaic use of delay effects in recorded sound—echo and reverberation—has its place in modern times, but the phenomenon has for long resided in the realm of mystical experience. The Greco-Roman mythical character Echo, a nymph condemned to repeat all that she hears, is a tragic figure by all accounts. Rebuffed by Narcissus, the heartbroken Oread hides herself in woods, caves and mountain cliffs. She withers away there in loneliness, her flesh wasting away and bones turning into stone till all that is left is her voice. In this reduced, etheric spectral state, all she can do is to reply to anyone who calls out to her.
