PolderbitS Sound Recorder and Editor helps users back up their old audio tapes onto their computers. This software also makes recording and editing audio easy. Users can record sound from different sources, such as in-line magnetic-tape player or microphone. They can also modify both recorded tracks and audio files already saved to the computer, adding effects and restoring audio quality, when necessary.
This is a trial version. It seems that the full product is no longer available for purchase.
