VVVV (Audio) --> GH (Surfaces)

... modeling surfaces depending on the audio output frequency of each channel of your favorite songs ... VVVV -> GH (via gHowl) Any requests?? :P

    this is extremely interesting....i can't get my head around what's actually being mapped: is it time on the x axis and amplitude on the y? or is it simply the loft between the left and right channel waveforms of the audio sample?

    I have a quite similar VVVV definition what I make a year ago that makes the same in real time. The problem was that the buffer gets stuck at 3 o 4 seconds running (GH side problem).

     

    Perhaps, now, with new versions goes better. I'm going to try.

    Guido -> Points that are on the Y axis have a Z height result of a weighted FFT of the left channel audio of the song. And the points are offset a certain value of Y axis have a Z height result of the FFT but the right channel.

    Ángel -> Connect your example with the new version of gHwol. Try lowering the number of slices (values) that you send to GH and you'll see as the refresh buffer

    Very nice work,

    I'm doing something similar with pulling audio files from movie scenes and mapping the conversations in rhino via grasshopper-controlling the radius of a sweep command-(like http://vimeo.com/9256428). I set up a vvvv file that runs through my microphone and into grasshopper, but would rather (need to) run the .wav file into vvvv.

    Was wondering if you could share your vvvv file or explain how you are getting values from your audio file?

    Puedo traducir a español. Si es más fácil para usted.

    Thanks m.english!

    If you want to analyze this example, you can find GH definition and VVVV patch in the new gHwol' release.

    If your tinkering this example, upload a video or screenshot, please!

    ;)

    thanks for the help used values from fft to sweep radii

    Hi Juanma,

     

    Estoy muy interesado en aprender como conectar vvvv y grasshopper, estoy aprendiendo del codigo que viene en los ejemplos de ghowl pero no logro escuchar las canciones que pongo en vvvv. Sabes como hacerlo?

     

    Gracias,

    Omar

    Hola Omar,

     

    Si no puedes escuchar las canciones que enlazas desde VVVV, prueba a enlazar sólo canciones en .mp3, ya que tiene toda la pinta que el problema es por incompatibilidad de formatos.

    Pasa algo similar con el tema de videos... VVVV no acepta video en formato .mov.

     

    Si sigue dándote problemas, cuelga el patch de VVVV o una captura de pantalla a ver si podemos arreglarlo, ok???

     

    Un saludo,

     

    Jma
