Query: Great cleaner, the difference is obvious

I used this product as a cleaner, not as a burner (yet). And as a cleaner, I used it manually only (no wizard yet).In the respect of cleaning, the results are really amazing. I recorded old songs from vynil disks played on a non-amplified turn-table.After normalizing the volume (which in fact magnified it several times), all the noise was increased tremendously and quality degraded badly. However, by using the cleaning tools in Audio Cleaning Lab 3.0, I was able to bring the songs to a good quality. Audio Cleaning Lab 3.0 saved me money freeing me from buying an amplifier!I observed though that the program fares better with music than with voice. When cleaning voice recordings the program provides quite mediocre performance.For music however, I think it is an excellent cleaner for the money.
