Funinhand Digital Music Player
Funinhand Digital Music Player the audio files which are compressed
using MPEG-4 aacPlus, the world's most powerful audio compression
technology, delivering high audio quality even for the narrowband
transmission channels used in mobile communications. The highly efficient
aacPlus is thus the crucial factor in the technical and economic feasibility
of mobile music services and is already being successfully used to
transmit music.
About aacPlus
MPEG-4 aacPlus is the combination of three MPEG technologies comprising
Advanced Audio Coding (AAC), coupled with Coding Technologies' Spectral
Band Replication (SBR), and Parametric Stereo (PS) technologies.
SBR is a unique bandwidth extension technique which enables audio
codecs to deliver the same quality at half the bit rate. PS significantly
increases the codec efficiency a second time for low bit rate stereo
signals.
SBR and PS are both forward and backward compatible methods to
enhance the efficiency of any audio codec. As a result, aacPlus
delivers streaming and downloadable 5.1 multichannel audio at 128
kbps, near CD-quality stereo at 32 kbps, excellent quality stereo
at 24 kbps, and good quality for mixed content even below 16 kbps
mono. This level of efficiency fundamentally enables new applications
in the markets of mobile and digital broadcast.

The members of the aacPlus codec family
aacPlus is the latest MPEG-4 Audio technology. aacPlus v1 is the
combination of AAC and SBR, standardized as the High-Efficiency
profile in MPEG-4 part 10 (HE AAC). aacPlus v2 builds on the strong
success story of aacPlus v1 and adds value in all fields where highest
compression efficiency for stereo signals is mission-critical. aacPlus
v2 is a true superset of aacPlus v1, as aacPlus v1 is of AAC. With
the addition of Parametric Stereo in MPEG, aacPlus v2 is the state-of-the-art
low bit rate open standards audio codec.
