[英]How do I get the sound level in Python?
For a project I am doing I need to get the live decibel level of my mic.对于我正在做的一个项目,我需要获得麦克风的实时分贝水平。
I have seen the plotters:我见过绘图仪:
# Print out realtime audio volume as ascii bars
import sounddevice as sd
import numpy as np
def print_sound(indata, outdata, frames, time, status):
volume_norm = np.linalg.norm(indata)*10
print ("|" * int(volume_norm))
with sd.Stream(callback=print_sound):
sd.sleep(10000)
But i just need the volume as an integer, how do I do that?但我只需要 integer 的音量,我该怎么做?
Just print the number instead of bars:只需打印数字而不是条形:
def print_sound(indata, outdata, frames, time, status):
volume_norm = np.linalg.norm(indata)*10
print(int(volume_norm))
