在Tkinter GUI中显示Matplotlib音频图形

import tkinter as tk
from matplotlib.figure import Figure
from matplotlib.backends.backend_tkagg import FigureCanvasTkAgg

root = tk.Tk()
root.title("音频图形")

fig = Figure(figsize=(5, 4), dpi=100)

ax = fig.add_subplot(111)

canvas = FigureCanvasTkAgg(fig, master=root)
canvas.draw()
canvas.get_tk_widget().pack(side=tk.TOP, fill=tk.BOTH, expand=1)

# 音频处理代码

# 示例代码：在图形中绘制一个正弦波
import numpy as np
t = np.arange(0, 2*np.pi, 0.01)
s = np.sin(t)
ax.plot(t, s)

tk.mainloop()
