Streaming audio refers to the delivery of sound content over the internet in real-time, allowing users to listen without downloading files. This technology enables access to various audio formats, including music, podcasts, and radio stations, through platforms like Spotify, Apple Music, and Pandora. Users can enjoy streaming audio on multiple devices, such as smartphones, tablets, and computers. The process involves sending audio data in small packets, which are played back as they arrive, ensuring a continuous listening experience. This method has become popular due to its convenience and the vast selection of content available.
