MP3 General Infor

English
Dear Customer
,
Thank you for buying the Philips MP3-CD Soundmachine. Y
our great new acquisition will allow you to
listen to up to 10 hours of CD-like quality music, using the revolutionary new music compression technology MP3. MP3 technology MP3 is short for MPEG1 Layer
-3 encoding and decoding technology
, a very powerful encoding
algorithm with which you can shrink down the orginal Digital Audio sound data with a factor of up to 10 without losing significant sound quality
.
Recording and Playback It is recommended to set your recording bit rate to 128Kbps, sampling frequency at 44.1KHz to achieve CD-like music playback quality
.
Since downloading MP3 files from the Internet, ripping songs from your own legal CD’
s and burning
MP3 songs onto a CD-R, are a delicate process, the quality of a MP3 song may vary by these process. Subsequently
, making a MP3-CD may not be entirely perfect.
As a result of the above imperfection, you may experience an occasional “skip” while listening, or an occasional delay in accessing “previous/next” title to MP3-CD’
s. This is
considered to be normal. A comparison chart is enclosed as below:
