2. The buttons on the dialog offer three flanging speeds and two warbling
effects. For a good example of flanging, choose the Fast option, click OK, and
play the sound.
DYNAMICS
Dynamics processing is used to change volume levels within a sound file.
Applying dynamics specifically adjusts the lower levels and higher levels in the
file to create more of a dynamic range, less of a dynamic range, or to keep the
amplitude of a file within a certain range.
NOISE GATING
When recording a sound, there is often an audible noise floor during silent
breaks. Noise is generated by many different things, including electrical
equipment, machinery, and traffic outside your window. When your sound
source is much louder than this background noise, it is simple to remove the
noise during silent breaks, where the noise is most noticeable, with a noise gate.
To apply a Noise Gate:
1. Open TUTOR1.WAV.
2. Move the cursor to a location between “Wow” and “Sound” and select Insert
Silence from the Process menu. In this dialog, insert one second of silence at
the cursor. Select OK. If the file’s status format is not set to a time format,
you will need to change this first before inserting silence in seconds. Close
the dialog and change the status format of the file by right-clicking on the
Selection Status Fields and selecting Seconds from the pull-down menu.
3. After inserting silence, create a new file (New/File menu). In the new file,
use Synthesis (Tools menu) to generate four seconds of noise at -60 dB
amplitude. Choose Noise from the Waveform shape list, enter 2,000 in the
Frequency field, and drag the Amplitude slider until the value is approximately
-60.
4. Next, copy all of the noise onto the clipboard and mix it to the beginning
of TUTOR1. To mix, choose Paste Special from the Edit menu and select the
Mix option. Use 100% for the noise (Source) and 100% for the voice
(Destination). You should now have a file with voice and a relatively low
hissing sound in the background.
