mcjAudioMation


Introduction




This program for Windows PCs will let you obtain animation data from audio files

typically, you'll apply this animation to objects like VU Meters, Bargraphs and Speakers  in music videos

but they can also be used as visual cues to synchronize character animations ( ex: dances )


History

History

Oct 8 2012
 -- released

Oct 19 2012
 -- added a key component ( mcjAudioMation.dsa ) that was missing in the initial release. Without this component the Daz script produced by don't work !


Installation

The zip package is found at the bottom of this page

unzip it in your daz content folder, typically C:\Program Files\DAZ\Studio\content\


once installed, it will appear in your content library, under Studio / Scripts / mcasual


YouTube Video




Open / PCM Wave  :  Loading audio files

Use the Open / PVM Wave menu to open your audio file

mcjAudioMation only accepts to load very standard .wav files.

meaning,  8bit or 16 bit PCM (uncompressed ) .wav files ,

mp3-encoded wav files wont load


 

once loaded the display will look like this




Save / Das Script  :  Creating an animation file for Daz Studio



Use the Save / Das Script menu to export the animation as a Das Studio script.

Specify the location and name for the daz-script file.

for example i save it as softcell_Left.dsa

you may want to save it in one of daz studio's content folders

for example, on my PC, i could save it in c:\program files\daz\studio\content\scripts\mcasual\mcjAudioMationData

Done! you can exit mcjAudioMation.


in Daz studio, select the object you want to animate.

for example, i selected the speaker, which is part of the free prop named mcjSpeaker

available here: https://sites.google.com/site/mcasualsdazscripts2/mcjspeaker



Then i either

    - drag and drop the softcell_Left.dsa file on the speaker
    - do a File / Merge / Daz Studio Files ....... and browse to your s
oftcell_Left.dsa file   
    
- Click on  softcell_Left.dsa  if it's in one of daz studio's content folders


Once that's done the following panel should appear


The speaker happens to have a morph channel named "Push-Pull"

In Daz Studio's Parameters panel, when this morph is at -100% strength,

the speaker moves back and when it's at 100 % it moves front

mcjAutomation's data is not expressed as percents, so

    -100% corresponds to "Key Value for Silent ( 0 ) = -1
    100% corresponds to "Key Value for Silent ( 1 ) = 1


Animating a VU Meter needle in daz studio


The needle in the prop shown below is simply a Daz Studio primitive-cylinder

when the YRotate parameter of the cylinder is at 42 degrees, the needle points to the left

when the YRotate parameter of the cylinder is at -42 degrees, the needle points to the right

so in this case we need to set :


 "Key Value for Silent ( 0 ) = 42
"Key Value for Silent ( 1 ) = -42



Save / Poser Pose  :  Creating an animation file for Poser, Carrara and Daz Studio


Use the Save / Poser Pose menu to export the animation as a Poser Pose file


A dialog window should pop up


in the Source audio channel list, select which audio channel ( left or right ) will "drive" the animation


in the Target Type list, select the type of target for this animation, choices are "Prop" and "Actor"


if the Target  Type selected is "Actor" ( figure), then in the Target Name field, type the name of the target body part, for example: "head"

Be careful and use exactly the body part name else the pose file wont be usable

if the
Target  Type selected is "Prop" then the name can be anything, for example, type the word "anything"


in the  Target Channel list, select if the animation will be applied to a morph channel or to one of the 10 standard  transforms.


if you did select "morph >>>" in the Target Channel list, then you must type a morph name in the "morph" field

this morph name must be exactly the name the target prop or figure uses. else the pose file wont be usable


for example, Aiko 3's morph named "OpenMouth"


when this morph is at 100%, the
Aiko mouth is fully open, when it's at 0% the mouth is closed.

mcjAudioMation doesnt use percents, so, we set "Value for silent" to 0 and "value for loudest" to 1.

bizarre quirk : in Daz Studio 3 at least, if you drag an drop a Poser Pose file ( .pz2) from a folder that contains daz script files (.dsa), thena daz script will be launched !! go figure.



Animating a VU Meter needle in Poser


In the VU Meter prop shown here,

when the YRotate parameter of the needle is at 42 degrees, the needle points to the left

when the YRotate parameter of the needle is at -42 degrees, the needle points to the right


so in this case we need to set :


Target Type = Prop
Target Channel = rotateY yrot
Value for silent = 42
Value for loudest = -42





Save / Sonogram  :  Creating a sonogram (spectrogram) image

Use the Save / Sonogram menu to export a sonogram of the audio clip.





 A spectrogram is a time-varying spectral representation (forming an image) that shows how the spectral density of a signal varies with time. Also known as spectral waterfalls, sonograms, voiceprints, or voicegrams, spectrograms are used to identify phonetic sounds, to analyse the cries of animals; they were also used in many other fields including music, sonar/radar, speech processing,[2] seismology, etc. The instrument that generates a spectrogram is called a spectrograph.

Note : the sonograms produced by mcjAudioMation are in uncompressed .bmp format.

A sonogram for a 30 seconds audio clip occupies about 1MB.

if the sampling rate of your .wav file is 48000 Hz, then the vertical axis of the sonogram covers the frequencies between 0 and 24000Hz

on the horizontal axis, 1 pixel covers a 1/30th second of audio

The intent of this feature is to make it a tool to help synchronizing events in an animation with a soundtrack.

This sonogram lets you "see" the sounds through time
