That feeling you get when the Adhan echoes through the evening...

Salam, as someone who isn't Muslim but is deeply moved by the Adhan-the call to the Maghrib prayer broadcasted from mosques-I wanted to share something. You know that warm, crackling sound from vintage audio? Some of the loudspeakers here in South India carry a similar quality, but it’s so much more than nostalgia. There's a distinct beauty in the recitation itself that just grabs me. No matter what I’m up to, when those soulful verses fill the air, I get chills every single time. Could anyone help me understand what I’m actually hearing? Is it the melody, the style of recitation (tilawah), or something deeper? Also, who usually performs it-is it a designated mu'adhdhin? I’d really appreciate hearing your insights.
