soundwaves and py Carrara

Posts: 38,180
is there a script I can use in this py Carrara thing that will use soundwaves to drive stuff?
I can create NLA clips using morphs, translations etc and use the mimic plugin to move things by assigning them to phonemes
but this is pretty random
I need something that reads pitch, volume and beat
tried to figure out Casual's mcjAudioMation and got more confused
most things seem to use only midi files, I basically want a waveform oscillator/battery type thing

I guess what I am trying to do is like animusic where events are driven by sound
I have a midi player piano prop from Rendo that I can use fenrics erc with to make the key movements drive stuff I suppose,
it uses a pz2 created from the midi track
but
my music I wish to use does not convert to midi very well
pretty awful actually
I have figured out Casual's script at least
Can ERC control any aspect of the emiter?
I guess you are looking for something called "python audio analysis" ...?
Maybe this: http://www.blendernation.com/2007/03/31/audio-analysis-script-with-tutorial/
thx Holly, will look
can save my wav file spectrum as numerical values from Audacity I see
need a spreadsheet program Ithink
but actually got as far as making them x,y co-ordinates! by hand but did not know what to do with it!
ctrl v into Carrara's formula thingy crashed it
not surprised
my video http://youtu.be/WnIP3G874a4 using mimic and morphs with physics
not representative of anything but an interesting music player Battery effect!
I did put it in my Blender python scripts but Blender leaves me baffled as ever!
interestingly my spreadsheet idea to generate a graph was not so dumb
I have no spreadsheet software on my desktop
(hence my inability to join that runtime render contest lol!)
yes, I SHOULD grab open office (or find my old download from my laptop) or something
but
you can indead create 3D waterfall graphs apparently of sound
I really want to use the data from the sound to do other things though
like make pretty patterns in the shadertab using a mixer function for example
hence formula, py carrara or fenric's erc as possibe ways to do this
but
how to get those audacity specrtum analysis numbers into a format Carrara can read?
that is the question
Casuals script works quite well for amplitude, in studio
I can indeed make a sphere move to the music or Genesis's pectorals!!!
cannot get it out into Carrara though, .duf, dae, fbx or any other export failed abysmally.
after bumping into furniture and kicking the guide dog in Blender trying to figure out that script
I found yet more to stress me
http://cgcookie.com/blender/2011/06/02/building-an-audio-visualizer-in-python/
noooooooooooo!
do not wanna use Blender (runs back to Carrara screaming!)
mm I wonder if something like this http://www.milkdrop.co.uk/downloads.htm captured and made into image sequences could drive something else using erc?
Recommend http://portableapps.com/
To have easy access to all open source apps.
Includes one click installation and start menu for blender, gimp, audacity, openoffice...
Maybe there is something to learn from this scene?
http://pycarrara.sourceforge.net/page6.html
Or PM f1oat?
I love you WENDY!!!! :P
lol! Rendero! I have py carrara plugin and read Frederic's info already
and it went straight over my little head housing a littler brain!
hence asking on forum
I need a readymade script to stick in, I cannot write one
even if it just moves a sphere up and down to the music!
can do the latter in studio using Casual's script btw
I saw what Fredric (f1oat) did with his trumpet and fingers
as I said, I have a midi piano figure from Rendo made for Poser and have indeed gotten objects to track the movements of its notes but only single ones, no way to switch to each active one for example.
Audacity puts out two rows of numbers for frequency and amplitude, if there was some way to read these numbers or put them in a format Carrara understands an image series for example, I could use them in a mixer in the shader room, displacement or something.
Fenric's erc plugin can drive stuff using shaders too, and leaves me just as baffled
this is why a third party software that converts wav to a visualization would work maybe.
an image series can be opened in the texture map diffuse channel and animate along the timeline, just shades of black white and grey needed.
it is very early morning, I go back to work this arvo
but Casual suggested this https://sites.google.com/site/mcasualsdazscripts2/mcjaudiomationtocarrara
which I will try to find time to try (in bed on android at moment, it IS 4am!)
ok, I post on the forum I swear so I can just work it out with help elsewhere (Casual on facebook) and share the results! lol!
Casual's camera pz3 worked and I can use Fenric's ERC to drive the displacement in a shader with the transform of the linked object
so got one very trippy syncronized to music video going
I can save my instrument tracks seperately and do multiple animations I guess too
idea is looking good so far http://www.youtube.com/watch?v=2EfCkXKSlrw
hopefully a hand strumming a guitar can follow a baseline etc
this is what audacity outputs for spectrum analysis
if only I could use it for plotting somehow

Wendy, I am not the biggest fan of your animations, but maybe I can help you out a bit. Houdini can do the things you want, but it is very expensive software. But maybe it can learn you things to do it your way. There is a very nice PDF as a starter. Visit his site for more info.
Download here
Two YouTube videos. There are more examples at vimeo.com. Search for CHOPS for Houdini (at Google).
Video 1
Video 2
Also do a search for: music visualizer
I'd like to learn about what Python can do in Carrara. it. I have MAX/MSP from Cycling 74, which makes it easy for me to do things like manipulate real-time data from Audacity, and I know enough to program in it reasonably. But I never wrote any Python.
And by astounding coincidence, the 64-bit version of Max/Msp/jitter was released 30 minutes ago. Jittrer integration with Carrara would be VERY interesting.
f1oat needs to get back to coding for us!
Yeah! :-P
And completely ignored again. I am wasting my time here on this forum. It looks like I do not belong to the (very small) Carrara elite here. I thought I help you out, looked for the info, spend time on it and what do I get, nothing. If someone helps me, I say thank you and / or respond. Yes, I know I am very weird.
This happens very often here. Recently in other threads too. Well, I have had it here. Probably never post here again. Fun for helping out others is over.
And completely ignored again....

I have a small suggestion that perhaps you try to not INSULT the person right at the beginning of your "help".... especially since it had absolutely nothing to do with the topic at hand, it just seems really rude, and if it were me I'd take anything you said after that little dig with a grain of salt - IF i read it at all.... Why did you feel the need to go there?
Everyone is human. If you have hurt feelings over your suggestion to buy $4500 software being ignored..., how would you feel if someone openly insulted your work? :smirk:
I will get moderated again if I respond how I wish I could.
just briefly
yes, I have Houdini apprentice
no I can barely do stuff all normal stuff like control a camera and render with it let alone plot soundwaves!
and I have tried, (using Houdini that is)
if you had looked at some of my youtube videos you would know I have gotten Carrara rigging and animation into Houdini.
so not entirely ignorant off it.
and I am not buying the starving artist version either!
yes, I know what a music visualizer is
my last video link had screen caps of one, Spectrum tab
and can also do battery/mandella/kalidioscopy type thingys with various software
I was exploring the posibility as I stated of using one to drive another action using Fenrics erc plugin
was NOT ignoring you but if you start attacking people who do not respond to your suggestions because maybe it is not what they were seeking
I will add to the list of oddly only Carrara forum members I ignore.
and while I was typing that lengthy some what edited response
Holly pops in, hi there!
what I would like and cannot find is f1oat/Fredric's py script for midi and actual project file!
Is he the one that used something like that to drive virtual speakers in a thread in the old forum? The thread would have been around the time Carrara 7 was released (if I recall.) It was very impressive.
Around the release of 8.0
It's still there somewhere - I caught a glimpse one day.
Yeah, that's it.
Ah, around 8. It's been awhile.
Can a MOVIE drive an ERC chain? Like can the overall brightness of an animation in a shader drive ERC? Or would it have to generate from a procedural for ERC to read it...?
3Drendero posted the link for py Carrara the previous page
http://pycarrara.sourceforge.net/page6.html
I have it, was what I was asking about
the video is on that site too but not the actual py script needed to use a midi file and drive events
and even if it were, I would need it set up to actually work in a project out of the box as I do not know scripting and coding.
Casual's script I also linked to drives a speaker cone to a music beat in studio
it took his suggestion of linking it to a camera and using his pz3 script to get it into Carrara but it works.
this is what I was speculating
yet to try it
yet to do a video based on a music visualizer
I imagine it would need to be very simple, shades of colours or brightness
using the "matrix" spectral analysis data would be a better way if it can be gotten into Carrara in some form
a movie can certainly drive a seconday event like displacement in 3D view used perhaps with bullet physics on another object
whether this need to be exported as morphs though to work?
am actually thinking Poser dynamic cloth dyntomorph like type morph sequences
what I hoped to do with fenrics objs exporter but it does not appear to support morphs and skinning.
if it did, ocean primitives and rustling trees could also be exported, I do them manually frame by frame and add as morph targets in studio.
yeah, I'd thought of the displacement-to-physics too..., but figured that should be avoided.
I have never made anything with ERC. Faba is so cool. :coolhmm:
I have a link to the original detailed ERC thread from the old Daz forums right here.
I agree, faba is amazing! ...and generous, imaginative, genius... :)
