Chris was able to take a cassette tape of music I had performed and recorded in the late 80’s, and convert it to a digital format. It was so important to myself and my family that it be preserved, as it was the last recording left in our possession. He was able to isolate and then eliminate a great deal of the background noises and static from the original recording which was phenomenal! I cannot recommend him more highly as Chris is so professional, and is really easy to work with, and pays such amazing attention to detail in his work! If you have the opportunity to work with him, I know you will feel as blessed as I was!

You know the message: that voicemail quality, the sound of a loved one's voice, the way it transports you to another time an place, makes you feel together with that person, the sound of their voice from across the country or across the globe through the mystery of modern machinery. And you just can't bring yourself to delete that message--you've heard it so many times and it brightens your day anytime you check your voicemail and you hear it once again. Why not add it to a mix tape?! Or start off a song on your new record with a whimsical personal message from a friend? Chris helped me do just that and his kind, professional, calm demeanor made the whole process enjoyable. And damn, drop dead ugly to boot.

Thank you so much for the speedy and excellent service in getting my 40 year old cassette tapes put into CD’s. My father recorded me and my sister in the late 50’s and early 60’s on a reel to reel recorder and then manually played those tapes into a cassette recorder. The final product in cassette is what you had to work with, background noise, page turns, even possibly some groans included, came out beautifully. But what a fantastic job of getting the music as authentic as possible.
Oh and one cassette was recorded from an actual long play record of my high school choir from 1966.
The best part is hearing my mother and father’s voices as they announce each piece.  And, Wow, we were really good for pre-teen kids!!!
So, Chris, thank you so very much. I’ll recommend your work to all my friends who may need this type of work done.
