1. pip安裝依賴

   pip install wave
   pip install numpy
   pip install soundfile
   

2. 立體聲音訊生成示例程式碼

   import wave
   import numpy as np
   import soundfile as sf
      
   # read wave files
   left_data, _ = sf.read("test_1.wav")
   right_data, _ = sf.read("test_2.wav")
      
   # A 2D array where the left and right tones are contained in their respective rows
   stereo = np.vstack((left_data, right_data))
      
   # Reshape 2D array so that the left and right tones are contained in their respective columns
   stereo = stereo.transpose()
      
   sf.write('stereoAudio.wav', stereo, samplerate=44100)
