为了统计大量音频的时长信息，比如总时长、平均时长、最大最小时长等，采用人工进行逐个的统计是不现实的，这就需要利用python进行批量处理。
那如何利用python获取一段音频的时长信息呢。具体如下：
wav_path = '' with open(wav_path, 'rb') as f: time_count =
f.getparams().nframes/f.getparams().framerate print(time_count)
那如何统计大量音频的总时长、数量、平均时长、最大最小时长等信息呢。具体如下：
import os # 音频存放文件夹路径 filedir = '' time_count = 0 wav_num = 0 wav_time_max = 0
wav_time_min = 5 list = os.listdir(filedir) for file in list: if '.wav' in
file: wav_num += 1 wav_path = os.path.join(filedir, fille) with
wave.open(wav_path,'rb') as f: wav_time =
f.getparams().nframes/f.getparams().framerate time_count += wav_time if
wav_time > wav_time_max: wav_time_max = wav_time if wav_time < wav_time_min:
wav_time_min = wav_time time_ave = time_count / wav_num
print(time_count/60,wav_num,time_ave,wav_time_max,wav_time_min)
