Audio Concepts:
Review AUDITION Features

Music and Variety
Your audio should have variety so that you can create an animation that will keep the audience's interest. Use audio that is soft and loud, dynamic and not dynamic, fast and slow, lots of texture, no texture, high pitch and low pitch. Becareful, too much variety will sound like chaos and too little will be like Techno.

gesture - a sound that draws attention to itself

texture - you can have a number of things happening all at once in music. The texture of a composition can be described by the number and quality of this layering of elements. Sometimes texture can be described as thick or rough or smooth or light texture. You can create a heavy texture by having background and foreground audio and also layering multiple sounds.

rhythm - is the variation in length of the sounds. Rhythm needs time. It also deals with the accentuation of the sounds over time.

melody - patterns of changing pitches and durations of sounds. Melody relates to pitch and requires rhythm to be there.

foreground and background audio - use layers of audio to create a more dynamic texured audio composition

Listen to lots of short audio compositions
Setting Up Projects:
File - Project - New Project (or Edit Current)
Change the project location to the D:/students/yourname and name the project
Use default
Animating Color:
Make an object and then open the Windows - Rendering Editors - Hypershade
Make a new lambert shader

In the Attribute Editor, change the color of the texture (only)
Assign the texture to your object

Go to the first frame of the color change and make sure the texture is selected in the Hypergraph and
In the Attribute Editor, RMB on the word Color and Set Key

Go to another frame and then change the color and RMB on Color and Set key
Repeat as often as needed

Remember that when you animator a texture color, it will be animated on the frames you set even if you assign that texture to another object.
Graph editor review
Can use the icons on the left Toolbar (4th from bottom) to jump directly to the Graph Editor

If you have not set your preferences before getting into Maya, (which you should really do), and you set keyframes, you will need to convert your curves to Weighted Tangents:

In the Graph Editor - Curve menu
Convert to Weighted Tangent

Reminder: the line is the change in the value of the parameter over time. You generally want the line to start gradually (spline) and then pick up speed then slow down. If the movement is robotic or abrupt, then you would not have the curve gradually taper as it comes to an end (use linear).

To see the color change curves in the graph editor, you need to have the Texture selected in the Hypershade and then in the Attribute Editor, click Load Selected

Look in the Graph Editor and you will see the RGB values - change them to splines and set the curves
Hierarchy and Grouping
Grouping objects:

Select the objects you want to group together and Edit Menu - Group or Control G
This creates a node and all objects are under this new node (don't forget to name it)

A group is useful if you want to animate a bunch of objects as a complete whole.
You can also animate the individual object by going into the group and setting keys on the individual object.

Ex: Set some keys on the group then go into the Outliner and set keys on an individual object.

Parenting objects:

Select the child first then the parent last (shift click)
Edit Menu - Parent or hit p
This makes the second object you selected the main node that will control the child object

You can animate the parent and the child will also animate but you can also go in and animate the child individually

You can also Middle Mouse button drag an object into the parent to make it a child

Make sure you center your pivots after grouping or parenting an object

You must select the group by selecting it in the Outliner before you move, rotate or scale it. You can just click the parent object to select it and you will control the child objects too.
Importing sound to Maya
Put the sound file into Maya - projects - YourProject - sound folder on the D:/students/yourname/yourproject/

File - Import

Select Audio All Formats
Select the sound folder

Go to the Timeline and RMB and select Sounds then select the name of your sound
It will show up in the timeline

Go to Window - Settings/Preferences - Preferences and select Timeline
Change Height to make it taller to see the audio better

Offset sound
Go to the Timeline and RMB and select Sounds then select the name of your sound then OPTIONS

In the Attribute Editor you can change the Offset to move the starting time of your audio by the number of frames you say.
Exercise 1: Synchronization
  1. Make an object like a torus or sphere
  2. Offset it from the center
  3. hit INSERT to place the pivot point in the middle of the scene
  4. hit INSERT again to turn it off
  5. With the object selected, Edit menu - Duplicate Special OPTIONS
  6. Edit - Reset
  7. Change the Rotate Y to 60 and make 6 copies
  8. Import a sound and increase your timeline Height
  9. Make another object and place it in the center
  10. Parent all your objects to this center object
  11. Each time you have a strong beat, make something happen to at least one of your objects
  12. You need to do each of the following at least once:
  13. Change the color
  14. Change the size
  15. Change the position
  16. Change the rotation
  17. Set keys on the Parent for at least one beat in your composition (we should see all elments effected)
  18. Save this file to turn in for a grade (A if you followed instructions, F if you did not turn it in)
