Extended Duration Noise

The audio opens with a continuous sound, reminiscent of an extended duration noise. It is a cacophony of static that buzzes persistently, much like the tuning sound of an old radio. The noise fluctuates subtly between the frequencies as if someone is trying to tune in to an AM or FM station. The sound is filled with an unsettling static that hovers in the background, merging with the varying pitch. The persistent, long-lasting noise serves as a constant reminder of the radio signals we are surrounded by. It's a blend of different noises that intermingle to form a unique, continuous sound that resonates in the background. The noise continues to play, with occasional shifts in its frequency, akin to the changing channels on a radio. The audio is a testament to the omnipresent radio signals that fill our atmosphere, captured as an extended duration noise.
