Play simple beep with python without external library

Question

Using only the modules that come with a standard python 2.6 installation, would it be possible to play a simple beeping noise?

So I would have to go through the default os's speech to text program? Also I am not using a mac all of the time. This would have to be cross platform. – Linseylinseywoolsey

Answer 1

If you're on a Unix terminal, you can print "\a" to get a terminal bell:

>>> def beep():
...     print "\a"
>>> beep()

Of course, that will print a newline too… So sys.stdout.write("\a") might be better. But you get the idea.

you can also do print "\a", and it won't do newlineb – Ardoin

also works on macs however it uses your speaker so if say you have headphones in it will use your headphones or if it is muted it won't work. – Poop

Works fine for me on Windows 7, even through headphones. – Californium

what is the main difference between print "\a" and sys.stdout.write("\a")? – Jiujitsu

@Jiujitsu that… is actually a more complex question than it seems. In this case, print "\a" is basically the same as sys.stdout.write("\a\n"); sys.stdout.write("\a") won't always work because sys.stdout is usually line buffered (so you won't "see" the write until a newline is written).

On windows:

import winsound         # for sound  
import time             # for sleep

winsound.Beep(440, 250) # frequency, duration
time.sleep(0.25)        # in seconds (0.25 is 250ms)

winsound.Beep(600, 250)
time.sleep(0.25)

On Android with QPython this is how it goes:

import androidhelper
droid=androidhelper.Android()
droid.generateDtmfTones('0',100)

This will place a beep of a certain frequency for certain time.

It's generateDtmfTones(). You're missing an f. kylelk.github.io/html-examples/androidhelper.html – Trent
