I have a code that takes a microphone input(when pressing "T)" and returns it as a float number (one final float number). However, when I yell or blow into microphone the maximum float it prints is 1 and no matter how I yell or say quietly after it printed 1, it keeps printing 1 only. How to change it to a bigger number. Let's say if I yell it would return a bigger number than if I just say quietly.

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using System.Linq;

public class MicInputs : MonoBehaviour

{

public enum micActivation

{

    HoldToSpeak,



}

public micActivation micControl;

private float sample_max = 0.0f;



public static float MicLoudFloat;

public List<float> recorded_values = new List<float>();

private string theMicroDevice;

AudioClip recordOfClips;

//microphone initialization

void MicroInitialization()

{

    if (theMicroDevice == null) theMicroDevice = Microphone.devices[0];

    recordOfClips = Microphone.Start(theMicroDevice, true, 999, 44100);

}



void StopMicrophone()

{

    Microphone.End(theMicroDevice);

    Maximum_Level(); // Collect the final sample

    MicLoudFloat = sample_max;

    print(MicLoudFloat);



}



void Awake()

{

    recordOfClips = AudioClip.Create("nameOfClip", 128, 2, 1000, true);

}

//AudioClip clip = myRecordedOrOwnClip;

//reate(string name, int lengthSamples, int channels, int frequency, 

bool stream,

//_sampleWindow = clip.samples;

//AudioClip _clipRecord = new AudioClip();

//AudioClip _clipRecord = AudioClip.Create("nameOfClip", 128, 2, 1, 

true);

int samplesWindows = 128;







//=========THIS IS THE START OF THE METHOD========





// get data from microphone into audioclip

float Maximum_Level()

{



    float waveData = new float[samplesWindows];

    int micPosition = Microphone.GetPosition(null) - (samplesWindows 

+1); // null means the first microphone

    if (micPosition < 0) return 0;

    recordOfClips.GetData(waveData, micPosition);

    // Getting a peak on the last 128 samples

    for (int i = 0; i < samplesWindows; i++)

    {

        float wavePeak = waveData[i] * waveData[i];

        if (wavePeak > sample_max)

        {

            sample_max = wavePeak;

        }

    }

    return sample_max;

    //float maximum_level = 0;

    //float waveData = new float[samplesWindows];

    //int micPosition = Microphone.GetPosition(null) - (samplesWindows 

+ 1); // null means the first microphone

    //if (micPosition < 0) return 0;

    //recordOfClips.GetData(waveData, micPosition);

    //// Getting a peak on the last 128 samples

    //for (int i = 0; i < samplesWindows; i++)

    //{

    //    float wavePeak = waveData[i] * waveData[i];

    //    if (maximum_level < wavePeak)

    //    {

    //        maximum_level = wavePeak;

    //        recorded_values.Add(maximum_level);

    //    }

    //}



    //float max = recorded_values.Max();

    ////print(max);

    //return max;





    //print(maximum_level);

The sensor returns only a 0 or a 1, it's not 0->inf, if you want to something else, like checking how load is the voice from 0 to 100, you could record it and check the audio file highest bump and return that.
