Shaders that change vertices with sound

This Unity script, MicAnalyzer, is designed to attach to a GameObject with an AudioSource component, allowing it to analyze and process audio input from a microphone in real-time.

Features

• Real-Time Audio Analysis: Capture and analyze audio data from the microphone.
• Volume Control: Dynamically read and adjust the volume level.
• Spectrum Analysis: Break down the audio into low, mid, and high frequencies for further processing.

How to Use

1. Attach this script to a GameObject in your Unity scene.
2. Ensure the GameObject has an AudioSource component.
3. Configure the sensitivity and frequency thresholds to match your audio analysis requirements.

Script Functions

• GetLoundness: Returns the current loudness level.
• Start: Initializes the microphone input and starts capturing audio.
• Update: Continuously calculates loudness and analyzes the audio spectrum each frame.
• CalcLoudness: Calculates the current frame's loudness.
• GetAveragedVolume: Gets the average volume from the current audio clip.
• AnalyzeSpectrum: Analyzes the audio spectrum and sets the material properties based on the low, mid, and high frequencies.

Parameters

• sensitivity: Adjusts the microphone sensitivity.
• resolution: Sets the resolution of the spectrum analysis.
• lowFreqThreshold, midFreqThreshold, highFreqThreshold: Define the frequency ranges for the spectrum analysis.
• lowEnhance, midEnhance, highEnhance: Multipliers for enhancing the respective frequency ranges.

Customization

You can control the influence of the last frame's loudness and the thresholds for frequency analysis through the public variables provided.

Materials

The script interacts with the material on the GameObject to visually represent the audio analysis through shader properties.

Notes

• The script uses the Microphone class to start capturing audio.
• It uses AudioSource.GetSpectrumData for spectrum analysis with a Blackman-Harris window for smoothing.
• The script assumes that the GameObject's material has shader properties named _Loudness, _LowSpectrum, _MidSpectrum, and _HighSpectrum for audio visualization.

Make sure to tailor the script's public variables to fit the audio characteristics of your project.
