Next, click the "Track Inspector Page" icon. Click "Track Effects" to display the screen that is used
to adjust the effect parameters.
Here, we're going to adjust the "Mix" value, one of the "Reverb" parameters. The larger the Mix
value, the more reverb is added. There's a little too much reverb at the moment, so let's drag this
meter to reduce the value to 10%.
A number of different effects are included, not just reverb. Click "Equalizer" to display an equalizer
that you can use to adjust the sound quality. Try using the equalizer to make an even better
sound!

It's finally time to save the song to a .wav file and create
the CD! But before we do...
Alright, we have a song that we copied from a record and a song that we created and recorded.
Now we should be able to save these songs to .wav or some other type of audio file and create
their audio CDs. Alternatively, we can convert these audio files to another format, such as MP3,
and play them on a portable music player.
But before we do, there's one more step that we need to take.
Take a look at the following figures. The figure on the left is the waveform of a song from a
commercially available audio CD. The right is the waveform of an audio file that was converted
from a song created in Sequel LE. What do you see? The waveforms are completely different,
aren't they?
Nearly every part of the waveform on the left reaches the upper limits, but not on the right. The
sound of the left is more powerful, and its overall volume is louder than those of the right.
If you transferred these two songs to a portable music player or burned them to a CD, you'll
hear the big difference when you play them in succession. If you played the left song and then
the right song, the volume of the latter would be so low that you'd increase the volume. If the left
song started again, you'd have to rush to lower the volume. What a nuisance to have to deal with
every time a different song is played! That's why we have to adjust the songs that we record and
create so that their volume and sound pressure are the same level as the songs on commercially
available audio CDs.
This process is known as "mastering". Let's master our songs before we save them to audio
files.
