Noise is a fact of life. Its all around us and much like in the Pant world the defintion of ‘weed’ is simply any plant you dont want to be there, so to is ‘noise’ a very broad catagory. Some sounds can be simply cut out, excised from the soudntrack. others are burried in multiple sounds and so are harder to isolate. One of the most annoying and common is simply Hiss and Hum. All these kinds of noise have a chance to be dealt with by digital audio editing tools but its important to also remember that the best form of noise reduction is to avoid it in the first place – good mic technique, wind sheilds and quiet shootign environments.
But even with the best of Mic technique there will stll be times when digital clean up is required. This is where Adobe’s Soundbooth comes in. A relatively simple audio tool Soundbooth CS3 is designed almost pruely for waveform editing and cleaning and tweaking. Soundbooth CS3 is not a multitrack system like Soundtrack Pro (although the newly relased SB CS4 is, but thats another story) Think of SBCS3 as a tool for preparing, cleaning and tweaking audio before it goes into a multi-tracker like SoundtrackPro or your NLE.
One of the core processes in Sb for noise removal is Noise Printing, a process where you are effectively taking an audio snapshot of what the noise ‘looks like’ and then instructing SB to remove that wave pattern. tis process allows for a selective removal of noise even when there are sounds around the noise that you want to keep. Most commonly hiss around dialogue.
We shall go over this process of noise removal in class today but to re-inforce the idea and for reference there is an excellent Video and Text tutorial online from Adobe which gos through step by step how to use the noise removal tools in Soundbooth.

The video tutorial is available from the excellent Adobe Design Centre. just select Soundbooth CS3 from the list of apps on the left hand side and then underneath choose the tutorial “Cleaning and Restoring Audio”.
There is also a text and image version of this tute here -

I also spoke today in class about Soundbooth’s bigger brother Audition. if you’re starting to take you audio seriously this tool is about as comprehensive as it comes, covering all abses from loop multitracking and loop sequencing to in-depth audio manipulation and audio physics. Whilst ProTools has lots of great big expensive hardware you can strap it to, Audition leads the way as an incredibly powerful software solution thats fast, effcient and inexpensive. Audition has long been popular in Radio and audio broadcasting and is icnreasingly seen a solid video production tool.
