hi i have a lenevo laptop. i also posses a sony walkman. i have some cassestes in which i have painstakingly recorded some favorite songs. i am now trying to record these songs on my laptop by playing the cassestes on the walkman. for this i have a stereo jack which i connect from the headphone slot of the walkman to the mic port of the laptop. i am using donar mp3 recorder software. after the song is recorded i find that the quality of the song recorded on laptop is miserable even though the song when played thru walkman is good to hear. i have changed the walkman/cassete and tried and also another software known as samplitude music studio which has mastering options (which i did not know to use) but i am not getting desired results. please advise me.
