Bus Starting Up

The audio begins with the low rumble of a bus engine starting up, coming to life with a powerful thrum that reverberates through the surrounding street. The bus is parked on a bustling street in the heart of Barcelona, near the University Pompeu Fabra (UPF-CS12), and the sounds of the city's everyday traffic can be heard intermingling with the bus's engine. As the bus warms up, the engine's steady hum is underscored by the hiss of airbrakes and the occasional beeping of nearby vehicles. The afternoon sun casts long shadows over the scene, the bus now fully booted and ready to begin its route. The audio gives a sense of anticipation, of a journey just about to commence. It's a common, everyday scenario, yet it holds a certain charm, especially for those familiar with the rhythmic pulse of Barcelona's streets.
