With TouchDesigner VJ Software you are able to create amazing loops that react with different audio sources, including audio files, microphones, external devices and internal audio (stereo mix). Watch the video below and start learning how to generate fantastic audio reactive loops for your favorite VJ software using TouchDesigner.
'Cloner Object' for VJing in TouchDesigner
TD allows you to easily create cloners like those in Cinema 4D, the workflow is totally different, but the results are very similar and best of all, procedural. If you are VJ, good news, you won't need to waste your time rendering this kind of footage anymore. You only need to set the object to be cloned, a template and a Geometry COMP (the cloner itself). The cool thing is that you can use anything as the template, including geometries and particles. You can watch the entire workflow in the short video tutorial below. It is important to notice that TD also includes an SOP called 'Copy', it works well with a few clones, but it is not the best alternative when dealing with many copies or clones.
Audio Spectrum and Reactive Visuals in Touch Designer
This node takes the audio signal in the time domain and represents it in the frequency domain (FFT), in this way you can take advantage of a more understandable and usable audio representation, emphasizing the human audible frequency range (20-20000 Hz). If you want your visuals to react with a specific frequency range, use an Audio Band EQ, an Audio Filter or an Audio Para EQ between your audio in and your spectrum. For low frequencies (kick drum, bass lines, etc.) boost the frequencies starting in 63 Hz, instead, for high frequencies sounds (lead melodies, hi-hat, etc.) try boosting the values below 8000 Hz.
