Hi,

Audio source is a DV recording.
Many of my home videos have these sound distortions. It's more frequent on some tapes than others. There are also tapes without these distortions. Video does not seem to be affected at all.

Anyone know what may cause a DV tape to become damaged in such a way? Time? Storage conditions? Airport scanner (which is what I always thought to be the case)?

The tapes are 4-10 years old.

Sample:

My question. Any way to correct these audio distortions? Software recommendations?

Thanks

No, airport scanner not.
However, there are many factors, including the worst enemy: magnetic fields.
The video is scrambled using an efficient algorithm so the errors would also be concealed, sould they be beyond recovery. Audio is not.
Clean the heads. Use the same type of band (same manufacturere, same model, same length). Use the original gear. Use a Sony DVCAM ias the last resort.

Maybe I'll have the time to hear the sound, but I'm fairy confident that this is the problem. Unless you recorded the audio overmodulated (clipping).
