When and how did you create the "AudioPeer" object at 4:30?

[kimthanhnhan]

nice bro ! thanks so much for the tutorials :D

When you convert the 20, 000 samples into 512, how does it work? Does it do something like assign the value of floor(k*20000/512) to the kth place in the array or does it take an average of the values?

[superpipe]

I thought samples were actual representations of amplitude values in time, being 44100 samples 1 second of the audio clip that is currently playing

Hi! This is a very fantastic tutorial, But I'm a very beginner in unity. Please write me, how can I join audio(music) to my audiopeer script and spectrum data? :)

[MsDomdo]

First of all thanks for this tutorial. This is really helpfull to get into this topic.

Is there the possibility to use live audio input? How can i choose my audio input device?

[dominikkomar]

For some reason I'm getting 140 errors about "Assets\Oculus\AudioManager\Scripts\Audio\SoundEmitter.cs(28, 52): error CS1061: 'AudioSource' does not contain a definition for 'time' and no accessible extension method 'time' accepting a first argument of type 'AudioSource' could be found (are you missing a using directive or an assembly reference?)" many of this kind some referring to time some to volume some to pitch and so on...

I am having trouble with unity recognizing the AudioSource type idk if I'm missing something that I need to download or if it will work as coded? I'll try and figure it out but i have a game object with the audio file on it and the script

[rassoltal]

I'm Unable to work it out, allthough i walked thru every steps in the video. I was able to instanciate all 512 of the cubes but the cubes aren't able to react to the music at all. Im using a standard 3D Cube and the audiopeer script seems to be work just fine. was there a missing step?

[permafrost]

: Error executing m_dryGroup->getSpectrum (samples, numSamples, channelOffset, windowType) (An invalid parameter was passed to this function. )
UnityEngine.AudioSource:GetSpectrumData(Single[], Int32, FFTWindow)
AudioSpectrum:Update() (at Assets/AudioSpectrum.cs:14)

Help plz!

[DoomsDayFortress]

Am I missing something? After you have the script you can play the audio but you don't explain how I can add audio to unity. Can you still help me with that?

[lollo]

the intro jingle is heavy - loud & heavy ;)
