What is the easiest way I can create a 'beep' sound from a Ruby program?

Question

I'm making a small ruby command line script and I wanted to know what the simplest way to have the program emit a beep is.

Answer 1

Try printing the audible bell character:

print "\a"

Answer 2

For Mac OS X:

system('say "beep"')

Conventional print "\a" didn't always work by some reason for me (MBA, 10.7.4)

Answer 3

For windows, use the win32-sound gem - Adding Sound to Your Ruby Apps.

To install:

gem install win32-sound

Then in Ruby:

require 'win32/sound'
include Win32
...
Sound.beep(100, 500)

For non-windows, looks like this could work: How to make beep sounds?

puts 7.chr

Answer 4

The easiest way is puts 7.chr

Here is a customize way

require "Win32API"
Beep = Win32API.new("kernel32", "Beep", ["I", "I"], 'v')
def beep freq, duration
  Beep.call(freq, duration)
end 

beep 600, 400

Answer 5

Try the following:

$stdout.beep
