Hey, if i get the spectrum with DSP\_FFT, how often is the spectrum updated?  
If i used it in the update by Unity, the spectrum updated one time per frame with new values?

When you access the spectrum data of a DSP, by calling `DSP::getParameterData`, you get the spectrum data for that frame of audio. Each time you `getParamaeterData` you will get the latest information.
