The Sound Designer II file, with the extension .sd2, is an audio file format that was originally developed by Digidesign for their digital audio workstation software, specifically for use in professional recording and editing environments. The format was widely used for its high-quality audio data storage and was particularly popular in the late 80s and 90s. It supports multiple audio channels and bit depths, making it versatile for various audio production tasks.
RealPlayer created RA for audio streaming. It makes use of various audio codecs from those that deliver high-fidelity sounds to those that record low bitrate audio data. Radio stations mainly used it for online streaming, but current formats have overthrown it.
