File

New
Create a new file.  A dialog box comes up asking you about the number of channels, samples per second, and bits per sample for the new file.  When you click OK a new wave of length 0 will be created.
Open
This allows you to select a wave file to open for editing.
Revert
This will reload a file, restoring the previously saved version and undoing all changes made since the file was last saved.
Save
Write the wave data to a wave file.  If this is a new file, you will be prompted to enter the file name.
Save As
Same as "Save", except that it always prompts you for a file name.
Close
Close an open file.  If changes have been made, you will be asked whether you want to save them.
File Info
Shows some information about the wave file, including number of channels, sample rate, bits per sample and length.
Exit
Exit the wave editor.

Edit

Undo
Undo the last change made (on the current file)
Redo
Redo the last change undone (on the current file)
Cut
Copy the selected section of the wave to the clipboard, then delete it from the wave.  Only those channels that are selected are cut.
Copy
Copy the selected section of the wave to the clipboard (selected channels only)
Paste Over
Paste the clipboard in the current wave at the selected position.  The clipboard overwrites the wave at that position.  If a section of the wave is selected, pasting is restricted to that section.  If the clipboard goes over the end of the wave, the wave is extended.  Pasting only occurs in selected channels.
Paste Insert
The clipboard is inserted at the selected position, without overwriting any existing wave.  The wave is extended to make room for the clipboard.  If a section of the wave is selected, pasting is restricted to that section.
Paste Mix
This is the same as paste over except that it mixes the clipboard with the existing wave.  A dialog box pops up asking you to select the volume of the clipboard wave and the "mixing mode", which is either add or subtract.
Paste As New File
Creates a new file and pastes the clipboard in this new file.
Delete
Delete the selected section of the wave.
Delete Selected Channels
Deletes the selected channels (as you would have guessed).
Crop To Selection
Deletes everything that isn't selected.
Crop To Selected Channels
Deletes all unselected channels.
Insert Silence
Inserts a silent section at the selected position.  The length of the silent section is determined by the length of the selection.
Insert Specific Silence
This does the same thing as Insert Silence, but allows you to specify the length of the inserted silent wave.
Select All
Selects the entire length of the wave.  It does not change the channel selection.
Select none
Unselect whatever is currently selected
Invert Selected Channels
Select all unselected channels and unselect all selected channels.

Tools

Select
When this is checked you are in selection mode (the default).  You can select a section of the wave by clicking and draging the mouse.
Draw
When this is checked you are in drawing mode.  You can "draw" a wave using the mouse.  If part of the wave is selected, drawing is limited to that selected section.  Note that if you go over the end of the wave, the wave will not be automagically extended for you, you'll have to use "Insert Specific Silence" or something similar to extend the wave so you can draw at the end of it.

Wave

Format (submenu)
Convert to mono
Convert the wave to mono if it isn't already mono.  All channels are mixed together.
Convert to Stereo
Convert the wave to stereo if it isn't already stereo.  If it is mono, the channel is duplicated.  If it is 4 or 5 channel surround, the rear left and right channels are mixed with the front left and right channels to produce a stereo wave.  The center channel (if it exists) is deleted (if you want to keep this you'll have to manually copy and paste mix the center channel).
Change Sampling Frequency
Change the number of samples per second in the wave.  A dialog box asks you what the new sample rate will be.  You can select a preset from the list or enter one yourself.  The "Resample Wave" check box is checked by default, and unchecking this will change the duration and pitch of the wave.  Presets include: 11025 Hz (telephone quality), 22050 Hz (radio quality), 32000 Hz (DAT long play), 44100 Hz (CD quality), 48000 (DAT / DVD quality) (I'm not sure whether DVD uses 48000 or 96000 Hz, so this is a guess).  Extremely fussy audiophiles might choose to do their editing at 96000 or 192000 Hz, but this uses a lot of memory.
Chanbe Bits Per Sample
This changes the number of bits each sample uses when stored in the file.  The more bits per sample, the greater the range of values a sample can have.  There are only 3 settings that can be used: 8 bit (values ranging from -128 to 127), 16 bit (-32768 to 32767), and 24 bit (-8388608 to 8388607).  16 bit is CD quality, 24 bit is DVD audio quality (and a good setting to use while editing.)
Mute
Mutes the selected part of the wave, making it completely silent.
Adjust Volume
Allows you to increase or decrease the volume of the wave.
Normalize
Makes the wave as loud as it can be without distorting.  You can normalize the wave to any volume you choose (100% is the default).
Fade
This does fade in or fade out on a section on a wave (meaning the volume steadily increases or decreases over the length of the selection).  You can choose the volume at the start of the fade and the volume at the end of the fade.
Adjust Balance
This allows you to adjust the balance of the wave.  It is typically done left to right to change the apparent position of the sound source.  You can select a mode from the drop down list.
Pan
This allows you to create a "moving sound source" effect on a wave with more than one channel.  You can choose the balance at start, balance at end and the same modes as those available in "Adjust Balance" above.
Invert Waveform
This flips a wave upside down.  If you do this on all channels of a wave it does nothing to change the sound.  But it is useful to add an interesting stereo effect to a wave.  Simply use "Invert Waveform" on one channel of a stereo wave (or a mono wave, after converting it to stereo) and listen (it's pretty cool how such a simple thing can sound so good).  It's also a great way to discriminate against people who use satellite & subwoofer speaker systems (it'll virtually kill their bass).
Phase Shift
This just "shifts a wave along" by adding silent samples at the beginning.  Like "Invert waveform", this is most impressive when used on one channel of a stereo wave.  The default value of 10 milliseconds is a good setting to use for adding a stereo effect to a wave (although you might like to try 5 milliseconds if you notice one channel lagging too far behind the other).
Resize Wave
This makes a wave shorter or longer, changing its pitch at the same time.
Reverse
This turns a wave around so you can listen to it backwards.
Shift
Shifts the wave up or down.  Not much use really, except to center the wave (click the "Auto Adjust" button).

Effects

Add Echo
This allows you to add an echo effect to the wave.
Differentiate
This is a wierd effect I couldn't think of a better name for.  It finds the "slope" of the wave (the difference between one sample and the next sample) at each point, and uses this to construct a new wave that usually has a somewhat more trebble sound.
Absolute
Pretty simple.  All it does is invert all negative samples to create an "absolute value" wave.  What you end up with is a distorted version of the original sound.
Increase Stereo Separation
This is a great effect that "widens" the stereo separation of a wave.  There must already be some stereo separation or this effect will not work.  It is similar to the "Wow Effect" in windows media player 8.  (And by the way, the only reason I have windows media player 8 is because it came with Windows XP and I can't remove it.  Winamp is much better, and I definitely won't install that DRM infected thing called windows media player 9.)

View

Zoom
You can select the scale that's used to view the wave, from 1:1 (1 sample per pixel) to 1:50 and above.  Zoomed out full, you can see the entire wave in the window.  You can keep the zoom window open while you do other stuff.
Fit wave into window
Does exactly that.
Fit selection into window
Same as above, except only the selected part of the wave is shown.

Other View Menu Items
There is a list of open files in the view menu, with a check mark next to the one you are currently looking at.  You can select different files from this menu.

Control

Play
Play the wave.  This plays the entire wave if nothing is selected, or the selected section if there is a selection.  There is currently no way to listen to one channel of a multi-channel wave.  If the file is big, it will take a few seconds to save the wave to a temporary file before it can be played.
Stop
A nice way of telling the computer to shutup.

Help

I shouldn't need to help you with this menu.
