Is there an inexpene way to transfer information I have stored on
audio cassettes to my computer so I can burn it onto CDs? I have tried
doing it through a digital voice recorder but the quality was
terrible.

You will need software for the purpose.  I use Polderbits, which is
available at http://www.polderbits.com/.  Cost is about &30.00 US. 
Instructions are also available from that site.  You will need to be
able to connect your audio cassette player (through the speaker
outlets) using an RCA cable to your sound card input.  Works easily
and simply.

Easiest budget way is to trnasfer audio cassettes voice to CDs

==============================
--  PRE   REQUISITES
==============================
-- a 2 Headed Mono Phone Plug Shielded Cable
-- a cassettes Player
-- a Computer with a SoundCard with Internet Connection and CD Burners
==============================
1. Hook up your cassettes Player with the auxiliary channel on your Sound Card
2. Download sound recoder program from the internet. One is
recommended on the bottom of the comment or else you can go search at
www.download.com
3. Turn on the program, play the cassettes while recording using the program.
4. Gathering all the files then burn the CD!

Inexpensive enough? Only cable, CDs, computer rental and some
electricity fee. ( I hope you have the cassettes Player )

WARNING!
The software 'fr34k-ga' suggested is a "spyware/adware" program. It
frequently downloads advertisements (taking away from your i-net
bandwidth) and displays them while you are using the program. If you
have a Cable/DSL modem, or don't mind your dialup crawling to a halt
occaisionally, then perhaps its not so bad.

A truely free (in cost and access to the source code) choice is:
Audacity for  Windows 98 (not 95), ME, 2000, XP, Linux, & Mac
Homepage: http://audacity.sourceforge.net/
Win DL: http://audacity.sourceforge.net/latest/audacity-win.php/audacity-win.exe

There are also freeware audio editors at NoNags. By definition of
their software, there would be no "spyware/adware", but do a quick
Google for "<program name> spyware" before you download any of the
stuff they have there; Just to double-check that the software hasn't
changed to "spyware/adware" since it was first released.

As for recording it to a CD, if you are using windows XP, the Media
Play can record audio CDs (see "Help and Support" in the Start Menu).
If you don't have XP there appears to be a few CD writing progs at
NoNags. I can't vouch for them, as I use Nero (Non-free, came with my
burner) and the WinXP builtin recording.

I hope this helps
If you need any other help, be sure to ask.

yes..it is a way!
But you need an Deck ...or any audio equipement who had an separate
audio output.You must plug in the cassete,and connect that audio eq
with the computer right so..te audio eq with jack plugged on out-put
and computer with the other jack(you need stere jack's and ..stereo
cable)in the line in ..and so..you can record the cassete's.You can
use  Jet Audio (the program for recording)..
