Edit the recording
- step 1: Delete unnecessary parts
When the recording is complete, the recorded sound is displayed as a waveform.
The waveform is displayed in two parts of the screen.
The upper part displays the entire waveform. The
lower part is used to actually edit the waveform. On
either display, the more you move to the right, the
more you move forward in the waveform's time. The
time unit on the top display is mn (minutes). The
unit on the bottom display is s (seconds).
The amplitude of the wave corresponds to the
volume level of the recorded sound. When the amplitude is large, the volume is high. When the
amplitude is small, the volume is low.
From the waveform display, you can see that there was a period of approximately 4 seconds at
the start of the recording where there was no sound. Following that, the sound of the needle
first touching the record was recorded with a slightly high volume level. The actual song begins
a little after the 6 second mark, after the characteristic noise caused by the needle touching the
record.
Click the Play button to play back the recording.
Carefully check what section is noise and where
the actual song begins.
First, let's delete this noise and the part of the
recording that doesn't have any sound.
Drag the pointer from the beginning of the song to
where the song actually begins.

On the "Edit" menu, click "Remove". This is all you have to do to delete the part that you don't
need.
Let's edit the last part of the song as well.
Drag the scroll box to the right to display the part
after the end of the song.
It's easy to see that noise was recorded during the time between the song ending and the needle
returning to its rest position as well as when the needle lifted off of the record. You don't need
these parts, either, so drag the pointer to set the range that you want to delete, and then on the
"Edit" menu, click "Remove".
You now have a song without any unnecessary parts.
