Audio Codecs - Sangean WFT-2D 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 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.
Bit-Rates
The following table summarises the maximum supported bit-rates for the various audio formats
that are playable on your radio. Higher rates may be playable in some cases but performance of
the product may be affected.

AAC (LC) 320 kbits/sec
FLAC (1) 1.5 Mbits/sec
LPCM (2) 1.536 Mbits/sec
MP3 320 kbits/sec
Real Audio 64 kbits/sec
WAV 1.536 Mbits/sec
WMA (3) 320 kbits/sec
All codecs support 2-channel (stereo) coded files only.
All codecs support sample rates up to 48 kbits/sec (includes 32 and 44.1 kbits/sec).
Files which have Digital Rights Management (DRM) protection applied will not be playable on
