wav转pcm格式

批量wav格式音频转换pcm格式音频

import os

path = './audio_1'#原始音频路径
new_path_pcm = './audio_new_pcm'#存储pcm音频路径
dir_path = os.getcwd()+format(os.sep)
pcm_files = []

for i in os.walk(path):
    for j in i[2]:
        file_path = dir_path+path[2:]+os.sep+j
        pcm_files.append(file_path)

for pcm_file in pcm_files:
    new_path_name = pcm_file.split('/')[-1].split('.')[0]
    print(pcm_file.strip()+'*')
    fp = open(pcm_file.strip())
    # if True:
    fp.seek(44)#wav 和pcm的区别就是wav在pcm的前面多了44字节
    data = fp.read()
    mergetd_pcm_name = new_path_pcm+os.sep+new_path_name+'.pcm'
    print(mergetd_pcm_name)
    fp_out = open(mergetd_pcm_name, "wb")
    fp_out.write(data)
    fp_out.close()
    fp.close()
