Tape Restore Live! is a free Winamp plugin that improves the sound of cassette tapes.

Some unique features of Tape Restore Live! are:

Software Dolby B remover

This is an advantage over using a hardware filter because the tape bias settings can be changed before the filter is used, which is especially useful if the sound of tapes has become dull because of tape wear and age. Also, any noise from the sound card is deminished by the Dolby B decoder. Calibration tones are provided to calibrate the software Dolby B remover against the encoder in the cassette recorder.

AZIMUTH correction

If the tape head is not set exactly identical to the setting when the tape was recorded, playing it back in mono or through a surround system will result in very ugly artifacts. The AZIMUTH correction calculates the correct tape head setting on the fly, and corrects for it, even if the tape head is moving during playback (which occurs on some tape decks).

FM Stereo hiss removal

Recordings from stereo FM radio stations often contain FM stereo hiss. This filter can remove most of the stereo hiss without damaging the real sound. (This filter can also be used for FM stereo recordings that were not recorded to tape.)
