my experience has been very positive, using Real Player software and the cleaning it up with adobe audition...and the additional plus is so much stereo stuff on You tube....I don't know what method the above two used, but again I say download the free real player software and try it...again I must note that I did clean it up 1. normalized to 100 percent, 2. clipped the intro and outro leader time..3. did clip restoration on some that were burned too hot
I plan on using alot of these downloads at a local radio station that wants to upgrade to stereo ,they were very impressed with the sound.
