Why is onAudioProcess returning the buffer over and over?

I feel like theres a very simple mistake here, I just cannot figure it out. Basically I am trying to record my voice and then store the chunks in an array as they come in. Heres the code:

 const audioBuffers = []
 var audioCtx = new AudioContext()
    navigator.mediaDevices.getUserMedia({ audio: true })
    .then(stream => {
    
        var input = audioCtx.createMediaStreamSource(stream)
        var processor = audioCtx.processAudio()
        //processAudio created below
        var outputNode = audioCtx.destination
        
        input.connect(processor)
        processor.connect(outputNode)
    
    });
    
    setTimeout(function(){
        audioCtx.close()
        console.log(audioBuffers)
    }, 3000)
    
    
    AudioContext.prototype.processAudio = function () {
      
      //reduce volume of output
      function edit(input, output){
          for(var i = 0; i < output.length; i++){
              output[i] = input[i] / 2
          }
          return output
      }
      
      //process audio
      var tuner = this.createScriptProcessor(bufferSize, 1, 1);
      tuner.onaudioprocess = function (e) {
          var input = e.inputBuffer.getChannelData(0);
          var output = e.outputBuffer.getChannelData(0);
          output = edit(input, output)
          audioBuffers.push(output)
      };
      return tuner;
  }

For some reason, the same array is pushed to "audioBuffers" everytime onAudioProcess is called.

Float32Array(2048) [-0.00006328763265628368, -0.00005047679951530881, -0.00003455079422565177...

This is the results from "console.log(audioBuffers)" why is this happening?

ValueError: X has 10 features, but LinearRegression is expecting 1 features as input

So, I am trying to predict the model but its throwing error like it has 10 features but it expacts only 1. So I am confused can anyone help me with it? more importantly its not working for me when my friend runs it. It works perfectly fine dose anyone know the reason about it? cv = KFold(n_splits = 10) all_loss = [] for i in range(9): # 1st for loop over polynomial orders poly_order = i X_train = make_polynomial(x, poly_order) loss_at_order = [] # initiate a set to collect loss for CV for train_index, test_index in cv.split(X_train): print('TRAIN:', train_index, 'TEST:', test_index) X_train_cv, X_test_cv = X_train[train_index], X_test[test_index] t_train_cv, t_test_cv = t[train_index], t[test_index] reg.fit(X_train_cv, t_train_cv) loss_at_order.append(np.mean((t_test_cv - reg.predict(X_test_cv))**2)) # collect loss at fold all_loss.append(np.mean(loss_at_order)) # collect loss at order plt.plot(np.log(al...
