Audio Engineering

National Audio offers expert engineering to protect the integrity of your recordings.

Audio industry professionals know that each different medium and recording format has its requirements and limitations. To get the best sound from your recordings, or to transfer them from one type of audio medium to another, remastering for the destination medium is required.

Our services include making audio levels uniform from selection to selection and between channels of stereo tape, graphic equalization when required and Dolby B noise reduction when appropriate for audio cassette duplication.
