用python编写播放切割wav音频且带有开始暂停按钮进度条的代码

好的，以下是可以回答的内容：

您可以使用Python中的PyAudio库来播放和切割.wav音频文件。您可以使用Tkinter库来创建GUI界面，包括开始、暂停按钮和进度条。

以下是示例代码：

import pyaudio
import wave
import threading
import time
import tkinter as tk
from tkinter import ttk

class AudioPlayer:
    def __init__(self, file):
        self.file = file
        self.chunk = 1024
        self.paused = False
        self.playing = False
        self.stream = None
        self.wf = wave.open(file, 'rb')
        self.p = pyaudio.PyAudio()
        self.total_frames = self.wf.getnframes()
        self.framerate = self.wf.getframerate()
        self.duration = self.total_frames / float(self.framerate)
    
    def play(self):
        self.playing = True
        self.paused = False
        self.stream = self.p.open(format=self.p.get_format_from_width(self.wf.getsampwidth()),
                                  channels=self.wf.getnchannels(),
                                  rate=self.wf.getframerate(),
                                  output=True)
        data = self.wf.readframes(self.chunk)
        while data != b'' and self.playing:
            while self.paused:
                time.sleep(0.1)
            self.stream.write(data)
            data = self.wf.readframes(self.chunk)
        self.stop()
    
    def stop(self):
        self.playing = False
        self.paused = False
        if self.stream is not None:
            self.stream.stop_stream()
            self.stream.close()
        self.p.terminate()
    
    def pause(self):
        self.paused = True
    
    def resume(self):
        self.paused = False

class AudioGUI:
    def __init__(self, file):
        self.player = AudioPlayer(file)
        self.root = tk.Tk()
        self.root.title("Audio Player")
        self.root.geometry("400x200")
        self.play_button = tk.Button(self.root, text="Play", command=self.play)
        self.pause_button = tk.Button(self.root, text="Pause", command=self.pause, state=tk.DISABLED)
        self.progress_bar = ttk.Progressbar(self.root, orient=tk.HORIZONTAL, length=300, mode='determinate')
        self.play_button.pack(pady=10)
        self.pause_button.pack(pady=10)
        self.progress_bar.pack(pady=10)
        self.root.protocol("WM_DELETE_WINDOW", self.on_close)
    
    def play(self):
        self.play_button.config(state=tk.DISABLED)
        self.pause_button.config(state=tk.NORMAL)
        t = threading.Thread(target=self.player.play)
        t.start()
        self.update_progress()
    
    def pause(self):
        if self.player.paused:
            self.player.resume()
            self.pause_button.config(text="Pause")
        else:
            self.player.pause()
            self.pause_button.config(text="Resume")
    
    def update_progress(self):
        current_frame = self.player.stream.get_write_available() / 4
        progress = int(current_frame / self.player.total_frames * 100)
        self.progress_bar['value'] = progress
        if progress < 100 and self.player.playing:
            self.root.after(100, self.update_progress)
        else:
            self.play_button.config(state=tk.NORMAL)
            self.pause_button.config(state=tk.DISABLED)
    
    def on_close(self):
        self.player.stop()
        self.root.destroy()

if __name__ == '__main__':
    gui = AudioGUI('test.wav')
    gui.root.mainloop()

该代码使用tkinter库创建了一个GUI界面，包括开始、暂停按钮和进度条，使用PyAudio库播放和切割.wav音频文件。您可以将文件名替换为您自己的.wav文件名。
