I burned an old dvd into cs4 which is an interview. The subject's voices are fine, however there is static in the background. Is there something I can do to silence this static?
Background noise, from many sources, can be problematic, though with some work, some background noise can be eliminated, or at least diminished. Everything depends on the frequencies of the noise vs the frequencies of the Audio, that you wish to keep. This ARTICLE gives some tips, and they might be helpful. Success depends so much on what you have, and what you need.
Good luck, and hope that some of those tips are helpful.
