I have some audio cassette with songs. Now I want to record/convert the songs in MP3 through my PC. For this I am using Sound Forge, AudiGrabber software. I have Stereo cassette player and also stereo Jack. But when I record the songs in PC, the quality is coming very poor, there are too many noisy sound in converted music. How, can I record good quality music without any noice from audio cassete?

Audio Cassettes of course didn't provide the best quality of sound so your computer is only recording what it can hear. Does the program you use contain any cleaning tools? I use Magix Audio Cleaning Lab to help "clean" the sounds produced from Cassettes. I don't have any cassettes that are terribly bad quality, but it does improve the sound quite a lot.
