Question

我尝试使用声音文件库将电报语音文件保存在wave音频文件中：

import numpy as np
l = [5,6,4,7,11,14,12,1,3]
l_sort = np.sort(l) #sorting elements of the list
evens = list(filter(lambda x: x%2==0, l_sort)) #extract even elements 
odds = list(filter(lambda x: x%2!=0, l_sort)) #extract odd elements
out = evens + odds

但我收到以下错误：

def ReceiveVoice(bot, update, user_data):

   voice = bot.getFile(update.message.voice.file_id)
   voice.download('file.ogg')
   data, samplerate = sf.read('file.ogg')
   sf.write('file.wav', data, samplerate)

Answer 1

您可以尝试使用ffmpeg从ogg转换为wav，方法是使用python的模块子进程执行以下命令行。

import subprocess
src_filename = 'captured.ogg'
dest_filename = 'output.wav'

process = subprocess.run(['ffmpeg', '-i', src_filename, dest_filename])
if process.returncode != 0:
    raise Exception("Something went wrong")

Answer 2

尝试一下

import soundfile as sf
data, samplerate = sf.read(input_ogg)
sf.write(output_wav, data, samplerate)

如何在python中的wave文件中转换Telegram语音
