MPEG-1 Layer II
Audio Codec
|
MPEG-1
Layer II (MP2)
optimized for
NXP Nexperia™
media processors
|
The fully ISO-compliant
Streaming Networks MPEG1
Layer-I & II software audio
codec brings
high-performance audio
encoding and decoding to
embedded systems that
require a low memory
footprint. Optimized for use
with the NXP Nexperia family
of media processors (with
TriMedia VLIW processor
cores), the software codec
is flexible, scalable,
cost-effective, and
easy-to-use. It can be used
in time-shift applications
where encoding and decoding
of MPEG1 audio and video
executes on a single
Nexperia processor. Low
frequency noise also makes
the codec an excellent
choice for security and
surveillance applications.
This codec delivers
CD-quality music with
performance near MP3 codec
at equal bitrates. The codec
can burn audio CDs four
times faster than real time.
The encoder converts
standard analog audio
signals into digital format,
compressing it in real time.
The result is an audio
elementary stream ready for
independent use or for
multiplexing with video.
Well-documented, easy-to-use
application programming
interface (API) is included
with the codec. The API lets
developers control library
behavior and provide all the
functionality for audio
capture, encoding/decoding,
and rendering
