Get spectrum data with volume 0?!

Unity

Hey, I need the spectrum data but the user should not hear the music. how can i implement this? i have set the volume by 0.001f but i hear it a little bit. :slight_smile:

As long as you are adding the FFT DSP before the fader, you can set the volume to zero and still get valid data from the getSpectrum call.

Hey, thanks for your answer!
I get all time the same value if i get the spectrum data and the volume is 0.
i have do this:

lowLevelSystem.createDSPByType(DSP_TYPE.FFT, out fft); fft.setParameterInt((int)DSP_FFT.WINDOWTYPE, (int)DSP_FFT_WINDOW.BLACKMANHARRIS); fft.setParameterInt((int)DSP_FFT.WINDOWSIZE, FftWindowSize); channelGroup.addDSP(CHANNELCONTROL_DSP_INDEX.TAIL, fft);

Apologies, by setting the volume to zero it is likely that the Event will then go virtual (from Vol0Virtual). To avoid that particular virtualization you can set the Event’s priority to highest.

Thanks cameron, this works :+1:
if someone have the same problem, i have done this now:

channelGroup.addDSP(CHANNELCONTROL_DSP_INDEX.TAIL, fft);
eventEmitter.EventInstance.setProperty(EVENT_PROPERTY.CHANNELPRIORITY, 0)
