Audio Codecs - Sangean WFR-70 User Manual

Audio codecs

Your radio supports a range of audio codecs which provide compatibility
with a wide range of Internet Radio stations. These also allow users to
stream music from their computers or to play directly from USB and SD/
SDHC fl ash memory devices.
Note that for any given audio codec, there are many streaming
protocols available, and thus even if an Internet Radio station uses a
supported format, this does not guarantee that every such station will
work with your radio. The radio stations database to which your radio
connects is checked for compatibility so that most stations should be
playable without problems. Similarly when streaming media from a
computer, while a codec may be supported, there can be many subtle
variations in formats, tagging schemes and protocols (even within
UPnP). In general your radio will play the supported formats with most
common UPnP servers.
