Section 5. Using MP3 player
MP3 is an audio file format that is commonly
used in portable audio players and to distribute
music over the Internet. Compared to
uncompressed (linear) audio formats such as
WAV, a much smaller amount of data is
required.
These files will have a filename extension of
“.MP3.” The MICRO BR can record and play back
stereo MP3 files.
The MICRO BR supports the following audio
formats.
MP3 (file extension: .MP3)
• 44.1 kHz
• 64 kbps – 320 kbps
WAV (file extension: .WAV)
• 44.1 kHz
• 8 bit or 16 bit
• Mono or Stereo
• linear
• AIFF
• WMA
• AAC
• ATRAC
• Ogg Vorbis, etc.
The MICRO BR cannot use files other than MP3
or WAV files.
There are many music distribution sites on the
Internet, and there are also numerous formats in
which song files can be downloaded from these
sites.
However, MP3 and WAV are the only formats
that the MICRO BR is able to play back.
Music files downloaded from iTunes or
SonicStage are not normally in MP3 format. In
the case of iTunes, song files are normally
downloaded from the iTunes Music Store music
distribution website in AAC format.
In the case of SonicStage, song files are normally
downloaded from the Sony CONNECT music
store distribution website in ATRAC3 format or
MP3 format.
If you want to download music files, make sure
that the format is either MP3 or WAV.
If you have audio files on your computer that
were imported and converted from a CD, and
want to hear them on the MICRO BR, you must
make sure that the converted files are in the MP3
audio format.
