如何创建批量剪切音频的方法？

import os

def cut_audio(input_file, output_file, start_time, end_time):
    command = f'ffmpeg -i {input_file} -ss {start_time} -to {end_time} -c copy {output_file}'
    os.system(command)

# 批量剪切音频文件
def batch_cut_audio(input_dir, output_dir, start_time, end_time):
    for file_name in os.listdir(input_dir):
        if file_name.endswith('.mp3') or file_name.endswith('.wav'):
            input_file = os.path.join(input_dir, file_name)
            output_file = os.path.join(output_dir, file_name)
            cut_audio(input_file, output_file, start_time, end_time)

# 示例调用
input_dir = '/path/to/input/directory'
output_dir = '/path/to/output/directory'
start_time = '00:00:10'  # 剪切起始时间
end_time = '00:01:30'  # 剪切结束时间
batch_cut_audio(input_dir, output_dir, start_time, end_time)
