Convert RA to OPUS

The RA file extension, short for RealAudio, is an audio format developed by RealNetworks in 1995 for streaming audio over the internet. It was widely used for online radio, music, and speech content, offering efficient compression and support for low-bandwidth connections. RealAudio pioneered real-time audio streaming, contributing to the early evolution of internet media. Though its usage has declined due to modern formats like MP3 and AAC, RA files were instrumental in enabling web-based audio playback before broadband became mainstream.

Opus, associated with Opus Audio, is an open, royalty-free audio codec designed for high-quality voice and music streaming. Introduced by the Internet Engineering Task Force (IETF) in 2012, it adapts seamlessly to various applications like VoIP, videoconferencing, in-game chat, and live music performances. Known for its versatility, low latency, and high compression efficiency, Opus is widely adopted in modern communication platforms and web applications, making it a cornerstone in contemporary audio technology.
