In this class, we will go through the process of importing audio tracks intoAudacity and introduce the anatomy of a sound wav. From there, we'll learn how to editthe wav, manage multiple audio tracks, record your own voice, and export your veryown audio track.</p><p>This training is assumes no former knowledge of audio editing or the physics of sound.</p><p>In this course you will learn:How to record soundHow to edit sound wavsHow to import audio tracks from an outside sourceAbout multi-layered audio tracks and mixingAbout labeling and managing recorded materialAbout adding effects, de-noising audio recordings, and balancing stereo sound</p><p>The difference between MP3s, AIFFs, OGG Vorbis files and how to export themMore as time permits</p><p>Where can you use Audacity?Download the program for free at Be sure to downloadthe LAME encoder located there as well.Use it for free in the Vitale Digital Media Lab or in the Weigle Information Commons</p></li><li><p>e Interface</p></li><li><p>AUDACITY SOUND EDITOR AND RECORDER INTRODUCTION </p><p>Some Handy Recording Tips </p><p>Prevent noise! </p><p>The best way to reduce noise in your recordings is to prevent it entering your </p><p>sound material at all. Here are some simple tips: </p><p>* Turn off your refrigerator and furnace/air conditioner during the recording </p><p>session. </p><p>* Watch out for telephones, cell phones, pagers, ticking clocks, lawnmowers, </p><p>etc. </p><p>* Avoid locating the recording session near airports, train tracks, fire stations, </p><p>noisy dorm halls etc. </p><p>* Hang blankets on the walls, to dampen a live room. Or record in a room </p><p>with wall-to-wall carpeting. </p><p>* If you can, record in a basement, to help isolate your session from outside </p><p>noise. You'll probably need to use the blanket-on-the-wall trick here, </p><p>since concrete walls make good sound reflectors. </p><p>* Record late at night to reduce traffic noise leaking in from outside. (It's up </p><p>to you to work this out with the neighbors.) </p><p>* Avoid fluorescent lighting and keep cell-phones a good distance away from </p><p>any equipment. </p><p>Get the desired signal as loud as possible (without clipping) into the microphone. </p><p>This allows you to reduce the gain, which will also reduce the low-level noise. The </p><p>further a microphone is away from the source, the more you have to amplify the </p><p>mic's input signal to get to a usable level. But, boosting the gain amplifies </p><p>everything, including background sounds and even the internal electrical noise of </p><p>the amplifier. Ideally, the microphone should be right on top of the source, with </p><p>the gain no higher than necessary to get peaks around -3dB. If you are doing </p><p>multi-track recording, record each individual track as loud as possible. Set the </p><p>final volume of each track during post-production mixdown. </p><p>SAVE YOUR WORK WHILE EDITING. SAVE YOUR WORK WHILE EDITING. </p><p>SAVE YOUR WORK WHILE EDITING.
