text: i have old cassette recordings that i would like to enhance with a computer program prior to re-recording it.? these are musical recordings that are losing sound quality. most are live recordings that i hope to enhance and eliminate background noise.i am thinking of a program that would work like a equalizer and allow me to adjust all qualities of sound. all you need is a sound cable (the same cable that goes out from your sound card to the speaker or sub)and a piece of software(ex: ahead nero  wave editor or creative wave studio). connect your cassette recorder's line out with your computers sound card's line in.if you are using live value 5.1 then from the creative surround mixer select line in as rec.then start the recording software and play the tape....done (don forget to save)(if you don't have live value or mixer then use the mic in line)  you can also use your microphone in  instead of line in just remember to lower the mic volume a little and windows recorder as well (you need to press record button in the windows recorder as it stops every minute).  with ahead nero wave editor u will also be able to remove the tape hiss if present.  alternately you can also record by a freaky method .use a microphone to record what ever the tape is playing...  and if you are looking for audio manipulation. then go for cakewalk sonar or a rare thing called adobe audition.i use steinberg cubase sx, its the best stuff i got.
