What is RealAudio?
RealAudio is a proprietary audio format developed by RealNetworks, designed specifically for streaming audio over the internet. Introduced in the mid-1990s, it was one of the first technologies to enable continuous playback of audio files without requiring users to download the entire file first. This innovation played a crucial role in the early development of internet radio and multimedia content delivery.
The format utilizes advanced compression algorithms to reduce file sizes significantly, allowing for smooth streaming even over slow dial-up connections common at the time. While it was once the standard for online audio, RealAudio has largely been superseded by more modern formats like MP3 and AAC, though legacy files still exist across the web.
