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.
