Python library for playing fixed-frequency sound

Question

Hi,

I have a mosquito problem in my house. This wouldn't usually concern a programmers' community; However, I've seen some devices that claim to deter these nasty creatures by playing a 17Khz tone. I would like to do this using my laptop.

One method would be creating an MP3 with a a single, fixed-frequency tone (This can easily done by audacity), opening it with a python library and playing it repeatedly.

The second would be playing a sound using the computer built-in speaker. I'm looking for something similar to QBasic Sound:

SOUND 17000, 100

Is there a python library for that?

Answer 1

This seems to be what you are looking for.

Answer 2

PyAudiere is a simple cross-platform solution for the problem:

>>> import audiere
>>> d = audiere.open_device()
>>> t = d.create_tone(17000) # 17 KHz
>>> t.play() # non-blocking call
>>> import time
>>> time.sleep(5)
>>> t.stop()

Answer 3

You can use the Python binding of the SDL (Simple Direct Media Library).

Answer 4

The module winsound is included with Python, so there are no external libraries to install, and it should do what you want (and not much else).

 import winsound
 winsound.Beep(17000, 100)

It's very simple and easy, though is only available for Windows.
