Audio Dropouts

Nothing in my opinion, is more irritating than audio dropouts.
Be it in music, speech or the sound track of a video, they are
extremely jarring and detract from the enjoyment.

Audio dropouts can be caused by many things, but usually
as a result of inferior/faulty equipment, buffer under-runs
or just plain sloppiness from who ever is recording the media.




They can occur on only one channel, both channels of a stereo recording, or even
all channels in a 5.1 or 7.1 surround sound recording.
The duration and "intensity" can also vary, making them not the easiest of things to remove.

This is especially true if the audio is part of a video's soundtrack, you can't just lop them off
otherwise the whole audio will become out of synch with the video.

If the dropout is only on one channel, copying the other (good) channel and pasting it in place
sometimes works, depending of course on the content, phasing and stereo field.

The other way of course is re-synthesizing it, from bits and pieces.
Slow going, but no real alternative.
That then, probably explains the clip below, from a well known broadcaster
who shall remain nameless. ;-)

Before, 5 dropouts in just 20 seconds, and it's not even the whole clip.



With a bit of effort and time, the result is much better and well worth it.
