A variety of problems can arise during audio restoration, which can affect the result. Here are some of the most common problems:
Excessive noise removal: removing too much noise can weaken or distort the audio signal.
Excessive removal of pops and crackles: Removing too much can result in unnatural sound or loss of important parts of the audio signal.
Sound Correction Errors: Sound correction errors such as clipping or distortion can degrade the audio signal.
Color changes: A change in timbre can mean that the audio signal is no longer faithful to the original.
Loss of original information: The removal of noise and other interference can result in important information of the original audio signal being lost.
Stereo errors: Errors in the conversion of mono to stereo recordings can cause the audio signal to sound distorted or unnatural.
Noise Reduction Errors: Noise reduction errors can weaken or distort the audio signal.
It is important to think and plan carefully to ensure the outcome is as good as possible. An experienced sound engineer can help to avoid these problems and achieve the best possible result.
