may use the Compress mode to transfer a song from an album that has been Rapid Archived, but
not compressed yet. You can select a track and compress it using the Compress mode, and then
download it to the SmartMedia

File Compression
File compression is the conversion of full CD-quality digital and analog music into an MP3 file
format. Setting the compression bit rate determines the size of the MP3 file stored on the hard
drive. The compression bit rate is measured in kilobits per second (kbps).
When recording, you can select one of three compression bit rates on the I-Mix. (See Set
compression bit rate below.) In addition, the I-Mix has the capability to play MP3 music that has
been previously recorded and will automatically select the bit rates, including 64, 96, 128, 164,
192, 256 and 320kbps. The I-Mix can play MP3s that have been recorded on a computer.
Set Compression Bit Rate
The I-Mix is equipped with three bit rates for recording: 128kbps (MP3s), 320kbps (MP3s), or
full CD quality 1400kbps (PCM). Music recorded at full CD quality is not converted to an MP3
file, has the highest sound quality and requires more storage space on the hard drive. Music
recorded at the compression bit rates of 320 or 128kbps requires less memory.
