Hi guys. A client of mine needs to convert a whole lot of audio into .mp3 format. Most of it is already on CD or in .wav format, so that's easy, but what's necessary to convert cassette tapes and vynil to digital format? Also, dumb question, but does a high-end sound card make the process go faster, or is that a function of the primary CPU? Where does that processing happen? If a good sound card is necessary or beneficial, please make some recommendations! We are getting her a new desktop, probably an i5 or i7, so it will be a nice rig, just want to make sure that it will also handle the audio easily & quickly. Anyhow, if you guys can please recommend hard & software needed to convert cassettes & vynil to .mp3, I'd appreciate it. Thanks!
