Glad you have the mp3 working your way Di, I knew you would get there.
So, Sound card.... Device Manager>>>Sound, it should give you details.
CD make. I have always liked Verbatim or Memorex, but I have found the cheapo ones from ASDA do the job nearly as well for a fraction of the price.
I have stopped burning CDs except for copies of the originals I used to use in the car. Nowadays I simply rip to my hard drive using my patented and highly efficient filing system. I have thousands of tracks all neatly filed.
I use:
EAC for ripping http://www.exactaudiocopy.de/ it is the best, but takes a bit of geting used to. FreeRip might be easier to start with.
XMPlay for playback, tagging, playlists http://www.un4seen.com/ very light on resources with excellent sound quality.
Audacity http://audacity.sourceforge.net/download/ for, welll, messing about, chopping tracks, normalising sound, that sort of thing
Normalising volume http://mp3gain.sourceforge.net/download.php this evens out the playback volume of tracks so that you are not upping or downing the volume manually all the time. It's dedicated to the job and easier than the Audacity version.
You will need the LAME enc.dll for Audacity and EAC to work on mp3. It is part of this download http://www.free-codecs.com/download/Lame_Encoder.htm
That should do for now.
