Current Audacity Tutorials

Audacity is the most commonly used audio editing software at CJSF.  It is free and open source, and cross-platform, so you can put it on your own computer without cost.  There are versions for Windows, Mac, and Linux.  
Sourceforge, the organization that coordinates the development of this software, has a collection of tutorials online at http://manual.audacityteam.org/man/Tutorials

Here's the table of contents:

How to import an audio file into Audacity (for example, an MP3 music file), edit it, then export the result.
Detailed instructions on connecting your audio source (be it a microphone, guitar or keyboard) to your computer, and then recording that source with Audacity.
How to edit a narration to fit the pace of the background music, and fade down the music so your listeners can hear your narration, useful in particular for podcasts.
A set of tutorials on making multi-track recordings, using three different specialist hardware configurations or using your computer's on-board sound card.
Detailed instructions on connecting your turntable, tape deck or MiniDisc player to your computer, recording from that device, then editing and exporting the recording so that you have separate audio files for each song on the original source ready to burn to a CD or import into a media player such as iTunes.
How to record audio that is playing on the computer such as streaming audio from Internet websites.
Techniques which on some stereo tracks may allow you to remove or isolate vocals (or other parts of a recording) from the rest.
How to make ringtones for your cellphone with Audacity and move them to the phone.

Another way to reduce noise using Audacity

I think this works - tell me how it works for you:

If  you have bothersome low-level background noise in your audio, try this:  Choose Amplify from the pulldown menu, and amplify by about -15 dB.  Choose Leveller from the pulldown menu, and set it to Light and to Noise Threshold of -20 dB.  Click OK.  After the processing finishes, choose Amplify again and click OK to raise the level by the suggested amount.  The softer noises that were deleted during the Leveller processing don't come back up.
