Audacity 1-2-3

This is a guide on how to install Audacity.

Download and Install

(The steps below are a short outline. For a more complete tutorial, please check out this guide.)

1. Audacity
   > Download the Audacity software from this page: Audacity Sourceforge Download
   > Follow instructions to install.
2. Lame Encoder (This will enable you to export your files in mp3 format)
   > Download the lame mp3 encoder from this page: Lame Sourceforge Download
   > Install the Lame encoder by following the instructions given in the previous link, or the instructions on this page

Note: We now recomment readers to install the Beta version only. The main advantage to the Beta is that it offers a much improved noisecleaning effect. The Beta version is actually quite stable, provided you avoid clicking too quiclky (e.g. double-clicking on the track). Some readers use the stable version to record, and the Beta to apply noisecleaning. Other readers will use the Beta for everything without having any major issues.

Configure

You might need to change the default settings in Audacity. This is to ensure that all our recordings are as technically uniform as possible.

1. Before opening Audacity, plug in your mic. (always plug in your mic before you start Audacity)
2. Open the Preferences Dialog Box: Edit > Preferences (or Ctrl + P)
3. Under the Audio I/O tab:
   1. Under Recording Device: select your mic from the pull-down menu;
   2. Select 1 (Mono) in the Channels drop-down menu (top right).
4. Under the Quality tab:
   1. Check that the Default sample rate is 44100 Hz
   2. Change Default sample format to 16 bit
5. Export setup:

• If using Audacity 1.2.6: Under the File Formats tab:

1. Uncompressed Export Format: WAV (Microsoft 15 bit PCM)
2. Under MP3 Export Setup, select Bit Rate of 128; click Find Library and locate and select the Lame encoder you saved:

* PC: in your Programs Folder, find the Audacity folder, and select the lame_enc.dll file

* Mac: in your Applications Folder, find the Audacity folder, and select the LameLib; press OK.

• If using Audacity 1.3: Under Import/Export tab:

1. Beside MP3 Library, click Find Library and follow instruction #2 above.
2. (You will have to define the other settings when exporting the files, by click Options in the Export dialog box.)

Get Acquainted with the User Interface

More great information:

• Toolbars and controls
• Using the Edit Menu
• Tracks and Waveforms
• Exporting MP3 files (remember we record in Mono channel)

Please note that all those tutorials are illustrated with screenshots from the stable 1.2.6 version of Audacity. There are slight variations in the beta version but the same settings need to be set there, too.

Help! my mic is missing! -- See last section on this page.

Test

TIP: audio is a lot of work for many computers. Always, always give your computer a little time to catch up -- whenever you click a button, whenever you stop, whenever you save, be a bit patient with your computer. Most crashes happen when commands are given too rapidly. Save early, save frequently.

Barest Basics

(Note: a short video is available here: Audacity vid )

Here we create and save an Audacity file: record, look, listen, and delete. (3 minutes!) We presume that you have already configured Audacity correctly (see above).

1. Plug in your mic (always plug in your mic before you start Audacity)
2. Start Audacity (quit and restart it if it was already open when you plugged in your mic)
3. Record: Click the Record button (red circle) and read this into your mic:
   1. "Peter Piper packed a paper pumpkin. Thank you thirty thousand thanks. Fine fun on the forums, fortunately."
4. Stop: Click the Stop button (square).
5. Save your project:
   1. File > Save Project and look at the save window
   2. Select the folder you want to save your project in (create a folder on your Desktop called LV, and a folder inside that called "testing" -- unless you have a better idea) and save.
6. Play: Click the Play button (green triangle) and listen for a bit, then press Stop.
   1. now press the spacebar ... press it again (it toggles play on, off)
7. Position the cursor at the beginning of a word (can you find the beginning?)
   1. leisurely press the spacebar four or five times.
      each time, it begins where you had placed the cursor)
   2. click the Play button (green triangle) and then the Pause button; press Pause ...again...
      (each time, it resumes from where it was paused)
   3. highlight an inch or two of waveform and hit the spacebar; press it again.
      (it plays the highlighted section and stops)
8. Zooming: Look at the waveform.
   1. click the + magnifying glass 3 times;
   2. click the - magnifying glass 2 times;
   3. highlight an inch of the waveform and click the 3rd magnifying glass
      (it fills the screen with what you've highlighted)
   4. now click the final magnifying glass.
      (it fits the whole file on the screen)
9. Delete your track: At the far left side of your track, click the X in the upper left corner.
   1. press Control-Z. Your track is back (because it undid your delete).
   2. press Control-Z. Your track is gone again (because it just undid your recording).
   3. press Control-Y (to redo your recording).
10. Now click the X again to delete the track.

Volume

How did your trial sound? Did you have to turn up the volume on your computer to hear it? Or turn the volume down so it wouldn't distort?

LibriVox files should sound very comfortable to listen to when your computer's volume control is set about halfway between the mid-point and the max-point -- that is, if you're listening on headphones or speakers. If you're listening to built-in speakers, it's much harder to judge the sound level.

• If a sound file requires maximum volume to be comfortably heard, it is Too Faint!
• If a sound file must be played at mid-volume to be comfortable, and feels uncomfortable or begins to distort at 3/4 volume, it is Too Loud!

To record with good volume, learn (right now) about input levels (the level at which your voice is put in to your recording).

• Set your input levels on your computer
  (the single greatest aid to audio quality)
  • on a Mac:
    • Applications > System Preferences > Sound:
    • select your microphone under Choose a device for sound input
    • and slide the Input volume up, usually to 3/4 or 5/8 mark.
  • on a PC:
    • Start > Control Panel > Sounds and Audio Devices
    • click the Audio tab.
    • Under Sound Recording Default device select your microphone from the drop-down menu and click Volume
    • most folks need to slide the volume higher to about 3/4 or 5/8 mark.

Mystery of the Missing Mic

Sometimes your mic goes missing. It might have been unplugged while you were doing some editing in Audacity, and now Audacity doesn't know it exists. Even though you plugged it in before you started Audacity, things happen.

If you ever start Audacity while your mic is unplugged... you can try to simply restart Audacity after you've plugged in the mic. Sometimes that works. But if your recording quality isn't looking so hot, follow these steps:

1. quit Audacity
2. plug your mic in
3. select your mic on your computer and set its input levels (usually 3/4 or 5/8)
4. start Audacity
5. and check that Audacity has your mic selected:

• In Audacity's menu bar, Audacity > Preferences...
• Audio I/O tab, under Recording, Device: select your mic* in the pull-down menu.

(*If your mic isn't listed, start over at step 1, and be sure you've done step 3 properly. If that doesn't work, restart your computer with the mic plugged in, and begin with step 3.)
