In-Depth Information
It allows for low-resolution versions of its sounds to be downloaded and
tested. Then if the sound clip is effective, a license can be purchased for
(usually) very reasonable terms. For commercial projects this is a
great way to go because it provides good quality sounds with a good
license.
An alternative, especially for students learning, is
http://www.freesound.org
.
The FreeSound Project has some great sounds released under a Creative
Commons Sampling Plus License (although you need to register to download
clips). Take a close look and read the full license for details of how to use the
sound and how it can be included in your project.
For this chapter, go to either of these sites, or to some other sound source of
your choosing, and pick up (as in download to the hard drive and save within
the Unity project file for Incursion; see step 1 in the upcoming tutorial for
details) the following sounds:
1.
Waves:
This should be a sound as though you are hearing the waves
rolling up on the shore. The version I am using is “oceanwavescrushing.wav”
(
http://www.freesound.org/samplesViewSingle.php?id=48412
). We will
use this sound whenever around the water of the EntryWay scene.
2.
Mechanical rumble:
This should be a low rumble as though heavy
machinery can be heard through a heavy door. We will use this sound
when approaching the entrance to the facility. I used “low_register.mp3”
(
http://www.freesound.org/samplesViewSingle.php?id=33843
).
3.
Walking sound:
This should be a subtle sound of someone walking
(preferably on cement). This sound is easy to overdo, so be sure to
remember this guy is supposed to be stealthy—so no stomping. I used
“WalkGravelLoop.wav” (
http://www.freesound.org/samplesViewSingle.
php?id=31152
). An alternative is “running gravel of dry leaves loop.wav”
(
http://www.freesound.org/samplesViewSingle.php?id=54778
).
4.
Pistol shot:
This will be used when Aegis (the player) fires his pistol.
I used “Gun-Pistol(One Shot).wav” (
http://www.freesound.org/
samplesViewSingle.php?id=37236
).
5.
Others as desired.
As you walk through the model, other sounds will
become obvious to use. Find some and place them as desired.
Tips and Tricks
Often a bit of editing is needed before a sound is “just right.” There are
many powerful audio editing tools on the market that can be purchased
for high-end sound editing. However, if you are looking for a cheap (as in
free) and reasonably powerful editing software, take a look at Audacity
(
http://audacity.sourceforge.net/
). It's Open Source and available for
Mac and PC. A very handy tool to have for those quick tweaks, or for the
occasional need in format conversion (although Unity is very tolerant of
sound formats).
