RealAudio scalable multicast files were used with RealNetworks streaming technology to describe multicast audio sessions. The session description can identify the streamed content and provide the connection details required by RealPlayer to join it.
This is a session-control file, not an audio recording. Its associated MIME types include application/sdp and application/x-sdp. The format belongs to older RealAudio streaming workflows and may depend on a compatible multicast server and network.
Open the file with RealPlayer on Microsoft Windows. If the file describes a multicast session, RealPlayer must also be able to reach the specified stream and network.
Do not expect the file to open as a standalone audio recording: it is a description used to start or join a stream.
A RealAudio scalable multicast .sdp file is not an audio file, so it cannot be meaningfully converted to MP3, WAV, or another audio format. It describes access to a stream rather than storing the stream's audio data.
If the associated stream is available, compatible playback or recording software may be able to capture it, but that is separate from converting the .sdp file itself.
