iDFX is an innovative patent pending technology that dramatically
improves the sound quality of your MP3 and AAC song files.

Both the MP3 and AAC audio formats are .lossy. encoding methods
that use data reduction methods to substantially reduce the file
size needed to transmit and store a song file.

Audio files contain complex signal information that is spread over
a wide range of frequency bands. At a particular time in a song
some of these frequency bands will have louder sounds in them
while other bands will have softer sounds.

The MP3 and AAC methods reduce the total amount of audio data by
using less accuracy to encode the softer sounds, making use of the
fact that loss of accuracy of the softer sounds is not as overtly
apparent to your ears as loss of accuracy of the louder sounds.

However, we have found that this loss of accuracy of the softer
sounds of a song does cause a recording to lose a significant
amount of the richness and fullness of the original CD recording,
leading to a somewhat .muffled. sound quality. For example, the
upper harmonics of an instrument note or vocal can be at a soft
level but they are very important to conveying the full rich sound
of the note, and they are typically highly diminished in an MP3 or
AAC song file.

iDFX compensates for this loss of spectral information by using
patent pending technology to re-encode your MP3 and AAC files by
intelligently re-synthesizing damaged or missing harmonics while
also insuring full low frequency range for the song.

iDFX also sets all your songs to the same standard playback level,
so you won't struggle to hear quieter songs or get blasted by
louder songs.

When you compare an iDFX enhanced song to the original MP3 or AAC
file, you'll clearly hear how iDFX for the first time allows your
iPod to provide the full rich sound of the original CD recordings,
completely eliminating the .muffled. sound of your un-enhanced MP3
and AAC files.
