Unity Script convert to C# And On GUI Text Convert to UI TEXt

I have this Unity script that I would like converted to C# if someone much better at scripting than I would be so kind as too.

Also I would like it to use the New UI text and not the On Gui text which I find very difficult to get to line up properly on canvases with multiple camera setups.

Code (JavaScript):

1. var qSamples: int = 1024;  // array size
2. var refValue: float = 0.1; // RMS value for 0 dB
3. var threshold = 0.02;      // minimum amplitude to extract pitch
4. var rmsValue: float;   // sound level - RMS
5. var dbValue: float;    // sound level - dB
6. var pitchValue: float; // sound pitch - Hz
7. private var samples: float[]; // audio samples
8. private var spectrum: float[]; // audio spectrum
9. private var fSample: float;
10. function Start () {
11.    
12.      samples = new float[qSamples];
13.      spectrum = new float[qSamples];
14.      fSample = AudioSettings.outputSampleRate;
15. }
16. function AnalyzeSound(){
17.      GetComponent.<AudioSource>().GetOutputData(samples, 0); // fill array with samples
18.      var i: int;
19.      var sum: float = 0;
20.      for (i=0; i < qSamples; i++){
21.          sum += samples[i]*samples[i]; // sum squared samples
22.      }
23.      rmsValue = Mathf.Sqrt(sum/qSamples); // rms = square root of average
24.      dbValue = 20*Mathf.Log10(rmsValue/refValue); // calculate dB
25.      if (dbValue < -160) dbValue = -160; // clamp it to -160dB min
26.      // get sound spectrum
27.      GetComponent.<AudioSource>().GetSpectrumData(spectrum, 0, FFTWindow.BlackmanHarris);
28.      var maxV: float = 0;
29.      var maxN: int = 0;
30.      for (i=0; i < qSamples; i++){ // find max
31.          if (spectrum[i] > maxV && spectrum[i] > threshold){
32.              maxV = spectrum[i];
33.              maxN = i; // maxN is the index of max
34.          }
35.      }
36.      var freqN: float = maxN; // pass the index to a float variable
37.      if (maxN > 0 && maxN < qSamples-1){ // interpolate index using neighbours
38.          var dL = spectrum[maxN-1]/spectrum[maxN];
39.          var dR = spectrum[maxN+1]/spectrum[maxN];
40.          freqN += 0.5*(dR*dR - dL*dL);
41.      }
42.      pitchValue = freqN*(fSample/2)/qSamples; // convert index to frequency
43. }
44. var display: GUIText; // drag a GUIText here to show results

just quickly converted it to c#. not sure if it works though

 

Thanks mikeymike,
I really appreciate that, it gives me a couple of error:

Assets/Scripts/SpectrumDataText.cs(8,28): error CS0664: Literal of type double cannot be implicitly converted to type `float'. Add suffix `f' to create a literal of this type

And

oh yeah didnt even notice that. that should fix it.

 

That fixed the errors but it's not showing the same stuff in the inspector as the unity script one. So how do I add a UI text to display the Spectrum data?

 

Code (csharp):

1.  
2.  
3.    public int qSamples = 1024;  // array size
4.    public float refValue = 0.1f; // RMS value for 0 dB
5.    public float threshold = 0.02f;  // minimum amplitude to extract pitch
6.    public float rmsValue;  // sound level - RMS
7.    public float dbValue;  // sound level - dB
8.    public float pitchValue; // sound pitch - Hz
9.    private float[] samples; // audio samples
10.    private float[] spectrum; // audio spectrum
11.    private float fSample;
12.  
13.    void Start () {
14.  
15.      samples = new float[qSamples];
16.      spectrum = new float[qSamples];
17.      fSample = AudioSettings.outputSampleRate;
18.    }
19.  
20.    void AnalyzeSound(){
21.      GetComponent<AudioSource>().GetOutputData(samples, 0); // fill array with samples
22.      int i;
23.      float sum = 0.0f;
24.      for (i=0; i < qSamples; i++){
25.        sum += samples[i]*samples[i]; // sum squared samples
26.      }
27.      rmsValue = Mathf.Sqrt(sum/qSamples); // rms = square root of average
28.      dbValue = 20*Mathf.Log10(rmsValue/refValue); // calculate dB
29.      if (dbValue < -160) dbValue = -160; // clamp it to -160dB min
30.      // get sound spectrum
31.      GetComponent<AudioSource>().GetSpectrumData(spectrum, 0, FFTWindow.BlackmanHarris);
32.      float maxV = 0.0f;
33.      int maxN = 0;
34.      for (i=0; i < qSamples; i++){ // find max
35.        if (spectrum[i] > maxV && spectrum[i] > threshold){
36.          maxV = spectrum[i];
37.          maxN = i; // maxN is the index of max
38.        }
39.      }
40.      float freqN = maxN; // pass the index to a float variable
41.      if (maxN > 0 && maxN < qSamples-1){ // interpolate index using neighbours
42.        var dL = spectrum[maxN-1]/spectrum[maxN];
43.        var dR = spectrum[maxN+1]/spectrum[maxN];
44.        freqN += 0.5*(dR*dR - dL*dL);
45.      }
46.      pitchValue = freqN*(fSample/2)/qSamples; // convert index to frequency
47.    }
48.  
49.    GUIText display; // drag a GUIText here to show results
50.  
51.    void Update () {
52.      if (Input.GetKeyDown("p")){
53.        GetComponent<AudioSource>().Play();
54.      }
55.      AnalyzeSound();
56.      if (display){
57.        display.text = "RMS: "+rmsValue.ToString("F2")+
58.          " ("+dbValue.ToString("F1")+" dB)\n"+
59.          "Pitch: "+pitchValue.ToString("F0")+" Hz";
60.      }
61.    }
62.  
63.  

didnt realise you wanted them to be public variables, fixed now. thats mondays for you

 

Awesome, that fixed that How do I make it so that I can use a UI text to display the spectrum data...? One of these days that is going to sink into my thick skull lol I know what you mean about Monday's

 

just replace GUIText display; with

Code (csharp):

1. public Text display;

youll need to add the ui namespace at the top of the script too.

Code (csharp):

1. using UnityEngine.UI;

 

Awesome, thanks mikeymike, now it's perfect
I really appreciate that man. Code is so not my thing, graphics on the other hand, so if you ever need any graphic help you just let me know
