从计算机中读取多个.wav文件并将它们合并到numpy数组中

import numpy as np
import wave

def read_wav_file(file_path):
    with wave.open(file_path, 'rb') as wav_file:
        # 获取.wav文件的参数
        params = wav_file.getparams()
        # 读取所有的音频帧数据
        frames = wav_file.readframes(params.nframes)
        # 将音频帧数据转换为numpy数组
        audio_data = np.frombuffer(frames, dtype=np.int16)
    return audio_data

def merge_wav_files(file_paths):
    merged_data = np.array([], dtype=np.int16)
    for file_path in file_paths:
        audio_data = read_wav_file(file_path)
        merged_data = np.concatenate((merged_data, audio_data))
    return merged_data

file_paths = ['file1.wav', 'file2.wav', 'file3.wav']
merged_array = merge_wav_files(file_paths)
