7 FIRMWARE OPERATION
7.5 Supported Audio Codecs
7.5.1 Supported Ogg Vorbis Formats
Parameter Min Max Unit
Channels 1 2
Window size 64 4096 samples
Sample rate 48000 Hz
Bit rate 500 kbit/s
Maximum window size for an Ogg Vorbis file is 8192, however only window sizes upto 4096 are
in active use with sample rates not exceeding 48 kHz.
With USB (12 MHz clock) sample rates above 46875 Hz are played back at 46875 Hz. There are
no sample rate restrictions for lower sample rates: non-standard sample rates can be played
back without a performance penalty.
Only floor 1 is supported. No known current encoder uses floor 0.
All one- and two-channel Ogg Vorbis files within the restrictions above should be playable with
this decoder.
Ogg Vorbis decoding supports Replay Gain technology. If the decoder finds a Replay Gain tag
in the song header, the tag is parsed and the player software uses it to adjust the sound level.
For a song without any Replay Gain tag, a default of -6 dB is used. For more details about
Replay Gain, see http://en.wikipedia.org/wiki/Replay_Gain and http://www.replaygain.org/.
7.5.2 Additional Formats
VS1000 Developer library contains a simple WAV decoder, which can be easily included into
your own applications. Currently the WAV decoder supports 8-bit ulaw, 8-bit linear PCM, and
16-bit linear PCM formats.
