Wrapping is an unusual form of clipping distortion where, instead of being flattened at the maximum and minimum amplitudes of the audio format used, samples are wrapped around and appear with the right shape but at the wrong amplitude. This form of distortion only occurs on digital recorders, but has been encountered on devices ranging from small, handheld units such as interview recorders to large, professional recorders used in the music and movie industries. The audible consequence of wrapping is a loud and aggressive form of distortion that can appear to obliterate the wanted signal.
Unwrap eliminates all wrapping errors and provides an Auto Level control that automatically normalises the unwrapped signal to 0dB. The results can be dramatic, even revealing speech and making it completely clean and intelligible where none was audible in the first place.
