Hybrid Audio Production
By combining MIDI and digital audio loops in a program like Acid, the
best of both worlds can be optimized. On the digital audio side (loops),
Acid will optimize a high quality playback format by playing back loops.
Only one copy of each loop used need be part of the file, saving space.
Using the MIDI features takes advantage of the very small data size of
MIDI instruction code and relies on the installed synthesizer of the playback
system, whether this is a software synthesizer, a custom wave table in
the game platform memory, or an external hardware synthesizer in a professional
recording studio. These features can also be created in Pro Tools.
Most MIDI editors will allow editing in a variety of views;
including Event List, Graphic (piano roll) and even Musical Notation
view. This is a great improvement on the original MIDI editors that
only showed a command line event list, similar to basic code programming.

Dynamic allocation allows for seamless playback of MIDI
data to be performed on a system with a limitied number of voices, such
as platform game machines and early sound cards. Early game audio tools
required detailed editing to ensure that only the maximum number of
voices was being used.

AKA: Animated, Animator
The process of creating the illusion of motion by creating individual
frames, as opposed to filming naturally-occuring action at a regular
frame rate. See also computer generated animation, claymation, time
lapse. Contrast with motion capture, rotoscoping.
All of the audio components in full motion picture are even more
critical when supporting animation:
- Dialogue Production
- Sound Effects
- Musical Score
Tips for spotting to cues in cut videos
- anticipate the action by sliding the cue forward and backward
- use the M key for initial spotting session; go through the whole
footage several times, placing and labeling markers
- think in layers! What is going on in the different areas of foreground,
middleground and background
- what is the most important sound in the scene?
