如何获得 Python 中的声级？

Question

For a project I am doing I need to get the live decibel level of my mic.

I have seen the plotters:

# 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?

Answer 1

Just print the number instead of bars:

def print_sound(indata, outdata, frames, time, status):
    volume_norm = np.linalg.norm(indata)*10
    print(int(volume_norm))
