I have installed on the pc realtek audio manager can anyone tell me please is it possible to record my old cassette tapes to the computer using this
thanks in anticipation

You could, but not very comfortably, and the quality would not be too good.
Get this program (or the previous version 10, probably cheaper)

also available at Amazon and most PC outlets.

It's great for even copying vinyl LPs to your PC.

I havent used realtek audio manager, but when i record music from my stereo to the pc i use Audacity. its free, small size and does a great job.

thanks very much that was much appreciated

I have transferred all of my cassettes to my pc using musicmatch jukebox 6.1 my sound card is an ac97. mmjb. availible at www.oldapps.com simply change recorder settings in jukebox to line in and record

Thanks for that you all seem to make it sound easy

I personally use Exact Audio Copy (EAC) to record music to my pc, it's free and has a simple, easy to use, no thrills interface. Make sure you have enough disk space on your hd for the recorded wavs!

I do copy the old cassette tapes to the computer using FlexiMusic Wave Editor, an audio recorder/ editor. Found related answer in FAQ at http://www.fleximusic.com/support/record01.htm
