Hello. We are a professional recording studio with multiple engineers who specialize in sound clarification from a distorted, buzzing, humming, or otherwise tainted sound source. We have tools and tricks we use to process the sound that will eliminate 99% of the problem, 99% of the time. Sometimes the sound is beyond repair, so a-lot will depend on your sound source. If it is fixable by any means, we can do it. We look forward to working with you. Best regards, -Evan Jaffee. Custom Cut Media Group.
