 Sound Studio is an applications program written specifically for the Apple
 IIGS computer for the purpose of loading, editing, and playing digitized
 binary sound files.  With Sound Studio, you can manipulate sounds in a manner
 similar to that of most graphics word processors.  Sound Studio was designed
 to run on a system having at least 512 Kbytes of memory and allows a user to
 perform the following functions:
 
   a. Input a binary or text sound file
   b. Display the sound data graphically
   c. Zoom in on selected areas of the data
   d. Cut and Paste selected areas
   e. Play the sound forward or backward
   f. Control the playback speed and volume
   g. Play sounds with echo
   h. Fade in and Fade out selected areas
   i. Scale the amplitude up or down
   j. Erase portions of the file
   k. Save edited files to disk

 3.0     THE CONTROLS
 
 Sound Studio was designed to provide quick access to the most frequently
 used controls needed for playing sound files.  The following paragraphs
 describe the function of each.
 
 
 3.1     BUTTONS
 
 PLAY - Plays the selected area or the whole sound file.
 
 STOP - Stops all sounds currently playing.
 
 LOOP - The selected area or the whole file is played continuously until the
        stop button is pressed.
 
 ECHO - Plays the selected area or the whole file with echo.
 
 ZOOM - Plots a high resolution graph of the selected area.
 
 
 3.2     SCROLL BARS
 
 DELAY -        The bar labeled 'D' controls the echo seperation.
 
 VOLUME -       The bar labeled 'V' controls the volume.
 
 SPEED -        The bar labeled 'S' controls the playback speed.
 
 LEFT CURSOR -  The pair of left-right arrows below the STOP button are used to
                control the position of the left edge of the cursor.
 
 RIGHT CURSOR - The pair of left-right arrows below the ECHO button are used to
                control the position of the right edge of the cursor.
 
 
 
 4.0     PLAYING SOUND FILES
 
 To play a sound file, use the OPEN option in the FILE menu to load a file into
 the sound buffer.  The volume and speed may need to be adjusted for proper
 playback.
 
 
 5.0     SELECTING AN AREA OF THE FILE
 
 Most of Sound Studio's controls work on a selected area or the whole file.  To
 select an area of the file, move the mouse cursor into the graph area and
 click the mouse button one time.  This will cause a tiny cursor line to appear
 in the graph.  The width of the cursor can now be adjusted by using the
 left/right cursor control arrows.  To unselect an area, simply click the mouse
 button one more time in the graph area.
 
 A faster way of selecting an area can be done by clicking and holding down the
 mouse button while dragging the mouse pointer left or right.  The cursor will
 follow the mouse pointer until the mouse button is released.
 
 
 6.0     SAVING FILES
 
 Files can be saved by selecting the SAVE or SAVE AS options in the FILE menu.
 When files are saved, the current speed setting is also saved so the next time
 the file is loaded the speed will be correct.
 
 
 7.0     LOOPING WITH ECHO
 
 To play the sound continuously with echo, click the LOOP button then click the
 ECHO button.  Clicking the STOP button will stop the sound.
