Usage

  1. Import the Spectrogram GPU Shader package into your project.
  2. Create an empty GameObject in your scene and attach an AudioSource component to it.
  3. Create a new Material and set its Shader to Custom/SpectrogramGPU.
  4. Inherit from SpectrumDataProvider, or use the SimpleAudioAnalyzer script to point to your AudioSource.
  5. Add the SpectrogramGPU script to an empty game object.
  6. Point to the SpectrumDataProvider.
  7. Attach a gradient to the script and select a time depth (the number of frames to keep). Be sure to set your material to clamping, repeat will have undesired effects.
