What kind of media can the iMP-900 support?
Standard Audio CD (8Cm, 12 Cm), CD-R, CD-RW DATA CD with MP3, ASF and
WMA.
The iMP-900 also supports Mixed CD (Data Track + Audio Track), CD-Extra
(Audio Track + Data Track), Multi-sessioned and packet written CD.
What is VBR?
VBR is "Variable Bit Rate". Some MP3 encoders support VBR. When enabled,
the compressor will use a bit rate that will fit the actual passage. If it is a complex
part, having much more variation in the sound, it will use a high bit rate. If there is
less variation in sound, it will use a lower bit rate. Usually, the average bit rate will
not be as high as a same-quality MP3 with CBR (Constant Bit Rate). However,
there is shortcoming that it's hard to keep track of the actual position that may not
be favorable when studying language.
