用python写一个wav切割代码

当然可以，以下是一个简单的Python代码示例，可以用来切割WAV文件：

import wave

def split_wav(input_file, output_file, start_time, end_time):
    with wave.open(input_file, 'rb') as wav_file:
        framerate = wav_file.getframerate()
        nchannels = wav_file.getnchannels()
        sampwidth = wav_file.getsampwidth()
        frames = wav_file.getnframes()

        start_frame = int(start_time * framerate)
        end_frame = int(end_time * framerate)
        if end_frame > frames:
            end_frame = frames

        with wave.open(output_file, 'wb') as out_file:
            out_file.setframerate(framerate)
            out_file.setnchannels(nchannels)
            out_file.setsampwidth(sampwidth)

            wav_file.setpos(start_frame)
            out_file.writeframes(wav_file.readframes(end_frame - start_frame))

input_file = 'input.wav'
output_file = 'output.wav'
start_time = 2.0
end_time = 4.0

split_wav(input_file, output_file, start_time, end_time)

这个代码使用了Python的wave模块来读取和写入WAV文件，可以指定起始时间和结束时间来切割WAV文件。
