Use DePopper to remove scratches from vinyl records. With DePopper you can get near-CD quality from your vinyl disks, while preserving the "vinyl sound". DePopper processes a list of files without requiring your interference. It also minimizes clicks, scratches and tape hiss while preserving trebles.
With DePopper you can normalize your songs in volume and/or frequency and remove the undesired 50Hz/60Hz interferences. Use its center channel extractor to extract the center channel from mono sources recorded with stereo equipment, eliminating noises that are not at the center. You can also filter frequency ranges and single frequencies. To increase usability, DePopper includes predefined presets for most frequent kinds of sources - and you can create your own presets.
