Converting audio file
T. SINGARAVELOU
Format of your choice.
I bought an Audio CD that works well. It
shows the file as Track01.cda, of 1KB size.
How do I convert this file to MP3 format?
Please explain.
S. JAYASHREE
Some of the most widely used audio file
formats are CDA, MP3, WAV and AU. In the
CD Audio, the .cda file has the representation
of the CD tracks and not the audio
information.
These representations are valid only for the
CD-ROM. The .CDA files can only be played
from a CD-ROM. They cannot be played from
a computer hard disk by copying the .CDA
files to hard disk. If the .CDA file is copied to
another media such as hard disk, then the CD
track representation is not valid for that
media.
Generally, commercial CDs use the CDA
format for distribution. The CDA files have to
be converted to another format, such as MP3,
to store them in a different media. The CDA
format has the higher sampling rate. The
quality of audio is superior to other audio
formats.
The MP3 format has the advantage of
higher compression without much loss of
audio quality. The file size is smaller by 1/10 of
its original size depending upon the bit rate
setting. The MP3 file can be distributed in all
media, such as CD-ROM, hard disk and any
removable media. The file can be copied from
one media to another. There are a lot of
converters available to convert the .CDA
format to .MP3 files.

Xilisoft video converter is another utility
that has a lot of audio and video conversions
in addition to .CDA to MP3 conversion. You

utility. This is compatible for Widows 2003

When converting .CDA files to MP3 files,
please ensure that the bit rate setting is about
128 kbps. The higher the kbps setting, the
higher the file size.
Also, the quality of audio is better. Most of
these conversion utilities offer the option to
choose a range of bit rate setting.
