This is a set of C# scripts which provides spectrum data with audio output. It provides spectrum data as a set of [octave bands] (http://en.wikipedia.org/wiki/Octave_band) which is commonly used in music visualizers. You can easily use these data to make audio visualization in Unity apps.
For a detailed example, see [the test branch] (https://github.com/keijiro/unity-audio-spectrum/tree/test).
- Import AudioSpectrum.cs.
- Import AudioSpectrumEditor.cs into the “Editor” directory.
- Add AudioSpectrum to a game object.
Number of samples
The number of samples which is fed to FFT. The higher number, the more accurate result, but reduce performance.
There are several octave band types.
- 4 band
- 4 band (visual) - only covers low and middle ranges
- 8 band
- 10 band (ISO standard)
- 24 band
- 31 band (FBQ3012)
The fall-down speed of the peak levels.
The coefficient which is used to calculate the mean levels. The higher value, the faster movement.
The array which provides the level of the each octave band.
The array which provides the peak level of the each band.
The array which provides the mean level for a short period of the time. These values respond slower than real-time values and suit for make smooth animations.
