Convert RA to AAC

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.

Advanced Audio Coding (AAC) is a digital audio file format designed to provide superior sound quality and compression efficiency compared to older formats like MP3. Developed in the late 1990s by a consortium of companies, including Fraunhofer IIS, Dolby, and Sony, AAC has become the standard audio format for various platforms, including Apple's iTunes and YouTube. It is widely used in streaming, broadcasting, and multimedia applications due to its ability to deliver high-fidelity audio at lower bit rates, making it ideal for bandwidth-constrained environments.
