File extensions: .RM or .RA for individual files and .RAM for streaming media.
Media that include the RealAudio and RealVideo proprietary, closed-source formats. Some components of server and client have been released under open-source-friendly licenses, created by Real Networks, Inc.
RealOne is the player for these and other audio and video formats. It is a feature-rich, cross-platform, and currently serves as an alternative the iTunes music purchasing service. In Windows, testing has shown annoyances such as extra icons, file associations, and Real's news pop-ups. Recent reviews confirm this.
RealOne supports a variety of Real Networks formats and a free version with some features disabled is available.
- RA - for Real audio
- RAM - for streaming
A free producer for the following formats is disabled but with many features disabled over the full version, including backwards compatibility with previous Real products.
We recommend FLAC.
Real offers two formats: a lossy codec, similar to MP3, Ogg Vorbis, and WMA. Real Audio has made its producer tool available to the public for a long time but is not the Best Compressed Audio Format. Real Audio is a great tool for compressing voice far smaller than MP3 and in mono (not stereo) format.
