Edit the recording
- step 2: Adjust the overall volume level
You used the CI1 GAIN controls to carefully set the volume level, but if you look at the waveform,
you can see that the overall volume level is low. You may think, "Oh no! I'll have to record the
song again". Don't worry. You can adjust the volume level of the whole song even after it has
been recorded!
When adjusting the volume level of the whole song, you just have to make sure that no parts
exceed 0 dB, which is the peak level over which the signal becomes distorted. The vertical center
of each waveform display is marked as ∞ (dB), and 0 dB is marked both above and below this
value. All you have to do is increase the volume and ensure that it stays within these 0 dB limits.
WaveLab LE 7 has a gain normalizer, a feature that automatically increases volume levels while
ensuring that they do not exceed this peak level. Let's give it a try.
On the "Processing" menu, click "Level Normalizer" to display the "Normalize level" dialog box.
Leave the default value of 0.000 dB under "Peak level after execution" as it is, and then click
"Apply".

Let's compare waveforms before and after gain normalization. The difference is very clear. If you
play back these waveforms, you'll also be able to notice the difference in their volume levels.
What's more, WaveLab LE 7 automatically makes adjustments so that the sound does not
become distorted even when the volume is increased. Simple, isn't it?
Saving the edited song
Now that you've removed the noise and adjusted the volume to a suitable level, let's save the
song that you've recorded.
• Saving the song as a .wav file
On the "File" menu, click "Save as" to display the "Save Audio File" dialog box.
