MP3: FRAUNHOFER CODEC
MP3 compression is probably the most popular format ever for sharing audio
over the Internet. MP3 has become so popular that manufacturers already started
making stand alone MP3 players so you can listen to your favorite MP3s even
without a computer nearby. The music industry tries to bring down MP3 as being
illegal which is absolutely not true! MP3 is here, and it is here to stay. That
is until a much better compression format arrives of course :)
In this part of the tutorial we will use the Fraunhofer IIS MPEG Layer-3
|Product: Fraunhofer IIS MPEG Layer-3 Codec
Author: Fraunhofer Gesellschaft
Platform: Windows 95/98/ME/NT/2000
In 1987, the Fraunhofer IIS-A started to work on a perceptual audio coding in the framework of the EUREKA project EU147, Digital Audio Broadcasting (DAB).
In a joint cooperation with the University of Erlangen, the Fraunhofer IIS-A finally devised a very powerful algorithm that is standardized as ISO-MPEG Audio Layer-3 (IS 11172-3 and IS 13818-3).
This revolutionary compression standard became popular under the name MP3. MP3
was the first compression standard that could provide near CD quality at a
decent compression ratio. Through the years the psycho-acoustic model of the
Fraunhofer encoders has improved providing even better quality.
The Fraunhofer codec used here is version 1.263 with Radium hack. Not
Fraunhofer's latest but without doubt their best encoder to date. The newer
Fraunhofer codecs offer better Variable Bitrate performance, but their output quality is lower than the good old 1.263. Avoid
'em! Nowadays Fraunhofer is surpassed in both quality and speed by LAME. When it
comes to Variable Bitrate encoding you better forget about Fraunhofer. It's just
not on par with LAME. If you really want the best encoder you better read the
LAME part of this tutorial. What Fraunhofer excels in is low bitrate encoding.
At bitrates of 128 kbit/s and lower no other encoder can beat Fraunhofer.
However, our goal is creating high bitrate (thus higher quality) MP3 files.
Obtain the Fraunhofer codec
The Fraunhofer Professional codec is unlike LAME not open source freeware
(yet another reason to use LAME). Therefore I cannot provide a download location
(and don't mail me for one). Anyway, for a seasoned Internet user it shouldn't
cost too much effort to find the Radium enhanced Fraunhofer 1.263 codec.
Configuring EAC for the Fraunhofer codec
Make sure you have Configured The Compression Options
in Exact Audio Copy.
From The EAC menu select Compression Options...
or press F11.
This opens the Compression options window.
