A lot of white background noise

NaNasuuAkiaa commented 2 years ago

Hello, when i try generating a file, either wav or mp3, when i reproduce it, it is filled with super loud white noise. Any idea of what is going on?

Thanks for the report. Can you give a few more details to help determine the issue?

What is the exact command you run? (starting with koch.py ...)
Windows/macOS/Linux version
Python version (python3 --version)
All python packages (python3 -m pip freeze) Use the same python command that you use to run your scripts, followed by -m pip freeze.

In case this is an interaction with another package, could you also create a fresh Python virtual environment, install only necessary packages, then try again?

Thanks. I don't have Windows so I can't confirm but my guess is this is a Windows+scipy issue. I assume when you don't specify an output file, it plays correctly? The noise only occurs in the output.wav file?

To confirm my guess, please try running the code example at the end of this page:

import numpy as np
from scipy.io.wavfile import write
samplerate = 8000
fs = 440
t = np.linspace(0., 1., samplerate)
amplitude = np.iinfo(np.int16).max
data = amplitude * np.sin(2. * np.pi * fs * t)
write("example.wav", samplerate, data.astype(np.int16))
