When importing uncompressed audio files into Audacity
Make a copy of the file before editing (safer) - Selecting this  means that Audacity will take longer to import files, but it will always have  its own copy of any audio you are using in a project. You can move,  change, or throw away your files immediately after you open or import  them into Audacity.
Read directly from the original file (faster) - Selecting this means  that Audacity depends on your original audio files being there, and only  stores changes you make to these files. If you move, change, or throw  away one of the files you imported into Audacity, your project may  become unusable. However, because Audacity doesn't need to make copies  of everything first, it can import files in much less time.
Uncompressed Export Format - This lets you select the format that Audacity will use when you export uncompressed  files. 11 common options are displayed in the list, but you can also select "Other" and choose a nonstandard file format for  Audacity to export.
Ogg Export Setup - Use this control to set the quality of Ogg Vorbis exporting. Ogg Vorbis is a compressed audio format  similar to MP3, but free of patents and licensing fees. A normal quality Ogg Vorbis file is encoded with a quality setting of "5".  Note that unlike MP3 encoding, Ogg Vorbis does not let you set a bitrate, because some audio clips are easier to compress  than others. Increasing the quality will always increase the file size, however.
MP3 Export Setup - Use these controls to locate your MP3 encoder and set the quality of MP3 encoding. Higher quality  files take up more space, so you will need to find the level of quality you feel is the best compromise. For more information,  see Exporting MP3 Files.

Spectrograms

You can view any audio track as a Spectrogram instead of a Waveform by selecting one of the Spectral views from the  Track Pop-Down Menu. This dialog lets you adjust some of the settings for these spectrograms.
FFT Size - The size of the Fast Fourier Transform (FFT) affects how much vertical (frequency) detail you see. Larger FFT  sizes give you more bass resolution and less temporal (timing) resolution, and they are slower.
Grayscale - Select this for gray spectrograms instead of colored ones.
Maximum Frequency - Set this value anywhere from a couple of hundred hertz to half the sample rate (i.e. 22050 Hz if  the sample rate is 44100 Hz). For some applications, such as speech recognition or pitch extraction, very high frequencies are  not important (visually), so this allows you to hide these and only focus on the ones you care about.

Directories

Use this panel to set the location of Audacity's temporary directory (folder). Audacity uses this directory whenever you work  on a project that you haven't saved as an Audacity Project (AUP file) yet. You have to restart Audacity (close and open it  again) for changes to the temporary directory to take effect.インターフェース
Autoscroll while playing - Scrolls the window for you while playing, so that the playback cursor is always in the window.  This can hurt playback performance on slower computers.
Always allow pausing - Normally the Pause button is only enabled while you are playing or recording. Checking this box  allows you to set the pause button anytime, which allows you to press Record and not have the recording start until you  unpause it. Sometimes starting a paused recording can be faster than starting to record in the first place.
Update spectrogram while playing - Because spectrograms are slower to draw, normally they are not drawn during  playback, but this option lets you draw the spectrograms anyway.
Enable Edit Toolbar - Sets whether or not you want to display the Edit Toolbar, which has some common shortcuts for  editing commands.
Enable Mixer Toolbar - Sets whether or not you want to display the ミキサー ツールバー, which lets you set the volume  levels and input source.
Enable Meter Toolbar - Sets whether or not you want to display the Meter Toolbar for setting audio recording and  playback levels.
Quit Audacity upon closing last window - By default on Windows and X-Windows (but not Mac OS), Audacity quits  when you close the last project window. If you uncheck this box, Audacity will open a new blank document instead of quitting.  To quit Audacity in this case, you must specifically select Exit (or Quit) from the File menu.
Enable dragging of left and right selection edges - Normally, when you move the mouse over the left and right edge  of a selection, the cursor changes to a left or right pointer, and you can adjust that edge of the selection independently. If  you don't like this feature, uncheck this box, and then clicking will always create a new selection (unless you hold down Shift  to extend an existing selection).
Language - sets the language used by Audacity. Language files are named "audacity.mo" and are found in the "Languages " folder on Windows and Mac OS X, or in /usr/share/locale or /usr/local/share/locale on most Unix systems. Audacity will  detect new languages the next time you start it.

Keyboard

This panel lets you change keyboard shortcuts. All of the commands that appear in Audacity menus appear on the left, along  with a few other buttons that can get keyboard shortcuts. To change a command, first click on the command you want to  change. Then type the new keyboard shortcut on your keyboard. Verify that the correct shortcut appears in the box below. If  it's what you want, press the Set button. Or to get rid of a keyboard shortcut, press Clear.
To reset to Audacity's defaults, press the Defaults button. This will get rid of any changes you have made.
If you have customized your keyboard layout and want to share it with someone else, you can press Save... and save your  complete keyboard layout as an XML file that you can share. To load an existing layout, press the Load... button and locate  the XML file.Mouse

This panel doesn't let you change anything, but it lets you view all of the commands and actions that you can do using the  mouse, many by holding down extra modifier keys.
