CDA Audio File Format Description
What is CDA?
CD Audio (.cda) tracks are audio files that can be stored on CD media.
The
.cda files are representations of CD audio tracks and do not contain the
actual
pulse code modulation (PCM) information. Cda files can be played only
from a
CD-ROM. To test a .cda file, either try to play a different .cda file
from
your CD-ROM or try to play a .cda file from a different CD-ROM. Copied
from
the CD-ROM to the hard disc it cannot be played. This is format used for
encoding
music on all commercial compact discs. If you buy a CD from a store, the
music on that CD is stored in CDA format.
The current standard for CD audio requires a sampling rate of 44.1 kHz
and a
sample size of 16 bits (2 bytes per sample). As a result, you need to
store
2 x 44,100= 88,200 bytes of data every second to record in mono.
Recording
in stereo would require twice that much storage. That extrapolates to
about
10 MB of data for every minute of stereo sound! It is for this reason
that
compression schemes such as
MP3
are so important.
Unfortunately, your computer can't store files in CDA format, so you
still
have to convert CDA files to another format to store on your hard disk.

Hi Y'all,
I have a cd of files that are for my ID mate Omni files. I put it into my
cd
drive and sent the whole batch to my documents, but when I try to open
them
nothing happens.
Each one is titled like this..
Track 01.CDA
Track 02.CDA
and so on. so what do I need to get these to read with Jaws 9?
I have xp pro and I also have win-amp 5.24 I believe.
I have tried to open these by pressing enter on them and then I tried to
open using the applications key and entered on play in win-amp, but still
nada.
Any help most appreciated.
Patricia
