In-Depth Information
To be clear, this means that there is currently no direct support for FMOD Designer functionality in Unity.
However, there are a few third party methods that allow some features of FMOD Designer to be used
within Unity, as well as some tools that of er middleware-like features. In addition, Unity's older FMOD
Ex based audio engine can itself be replaced by a dif erent one through the use of plugins. These are
described in the paragraph below.
Extending Unity's Engine: Supported
Audio Formats
Like quite a few other game engines, Unity Pro also supports the use
of plug-ins. These provide more or alternate functionality than can
be provided through the C# scripting interface. This extends to audio
engines as well. Both Audiokinetic's Wwise and FMOD Studio (the newest
version of FMOD) have now some level of integration available in Unity's
Editor. This essentially bypasses Unity's own audio engine, replacing it
with the plugin's version. It must be noted that this integration is very
low level, however—you'll have to trigger any Wwise or FMOD Studio
events completely through code or scripting from Unity.
Supported audio formats for Unity include:
•
Uncompressed Audio support
: Unity supports WAV and AIFF, the two
most common audio formats in use today.
•
Compressed Audio Support
: Unity supports both import and
playback of MP3 and Ogg Vorbis i les. Ogg i les are supported
in desktop applications (Mac, PC and Linux) while MP3 i les are
supported on import for all platforms.
•
Modtracker Support
: Unity supports four formats of Modtracker i les
which of er incredibly compressed i le sizes (these are actually MIDI i les
combined with compressed sample data, made popular in the nineties).
•
Audio Encoding
: Unity can encode uncompressed audio into Ogg
Vorbis for desktop applications, and uses MP3 for mobile applications
due to the presence of hardware decoders that support it.
Support for Filtering/Ef ects
Because Unity uses FMOD's audio capabilities, it does come with a lot of
extra DSP-oriented features. These features are mainly only supported in
the Pro version and include the following:
• Low Pass Filter
• High Pass Filter
