python 对比两个音频文件获取音准音高

需要自定安装相关插件，具体实现代码如下，文件地址通过命令输入即可，执行命令如下

python3 music.py pathAudio1 pathAudio2

music.py文件代码如下

import librosa
import numpy as np
import json
import sys
import logging

        raise

    avg_pitch = np.mean([p for p in pitch if p > 0])
    return avg_pitch

# 运行对比并输出结果

    print(result_json)
except Exception as e:
    logging.error(f"An error occurred: {e}")
