Recently, I posted an article about the basics of removing audio problems, and the limitations that you face right out of the box when you go to fix some nasty audio. This time around, we are going to talk about removing a very specific type of audio problem: hiss.
What is Hiss?
Not to be confused with hum, hiss is a persistant noise on a recording that sounds like … well … hiss. Turn the sound up loud enough and you will almost always here some on your recording. A low levels, it isn’t much of a problem.
The problem is when you have hiss on a recording that is distracting – say from a bad microphone or from turning up low dialogue. You could also be trying to restore an old recording that has hiss on it. Wherever it comes from, however, it’s annoying and needs to be destroyed.
