Play a sound, any sound [closed]

Question

Your program has to make the computer produce a sound, any sound.

Shortest code wins, not sooner than 10 days after the first valid answer. If there is a tie, the one submitted sooner, wins.

• The program should run on a reasonable, not too uncommon personal computer.
• Opening a pop-up, message box, etc. (for example, on a web page) does not count, as they might or might not produce a sound, depending on a lot of settings.
• Just entering a wrong command or invalid character on a console and receiving a warning beep does not count, just as the compiler/interpreter/OS beeping on an error or crash does not count either. Your code must be a valid program.

Answer 1

bash (13)

sudo rm -rf /

The faster the hard drive the better the sound. Don't work with SSDs.
(Don't try this at home, sudo rm -rf / erases everything on your hard drive)

Answer 2

*sh (5)

eject

(does not work if you have no CD/DVD or similar drive..)

Answer 3

Befunge, 0

If I read the spec correctly, this is an endless loop.
Endless loop = you'll hear your CPU cooler spin up.

Answer 4

sh 7

w|aplay

Plays a short noise.

Also 7:

aplay *

Assembly

Another non-bell solution. Resulting binary is just 15 bytes.

mov al, 182
out 43h, al
out 42h, al
mov al, 16
out 42h, al
mov al, 3
out 61h, al
ret

Assemble with nasm sound.asm -o sound.com. Can be tried with dosbox sound.com.

Answer 5

brainfuck: 8

+++++++.

Prints the bell character.

Answer 6

bash (Mac OS X) 5

say a

although stylistically I prefer the somewhat longer:

say 'Hello, Code Golf !'

Answer 7

dc, 2 chars

this one prints the bell character, too:

7P

Run with $ dc <<< 7P or save 7P to file and run $ dc file.

Also:

Befunge, 2 chars

Similar but infinitly looping and beeping:

7,

Answer 8

Haha, good ol' QBASIC code.

BEEP

Answer 9

Python 3.3.3, one character

<bell character>

The error message will contain a bell character, causing the sound.

Python 3.3.3, 10 characters

If errors are not allowed, this solution won't output the error message, only the sound.

print('<bell character>')

Answer 10

Golfscript 3

'.'

(where the . is in fact a BELL character)

The HEX representation of the above code is:

27 07 27

Answer 11

Java - 222

Enough of this bell character or predefined beep function stuff, this makes a real sound :)

import javax.sound.sampled.*;class S{static{try{SourceDataLine
l=AudioSystem.getSourceDataLine(new
AudioFormat(4000,8,1,0<1,0>1));l.open();l.start();for(byte
i=9;i!=0;i+=9)l.write(new byte[]{i},0,1);}catch(Exception e){}}}

Answer 12

DOS Prompt / DOS Script

a:

Requires 3.5" floppy drive :)

Answer 13

J (2)

a.

This prints all the characters from 0 to 255, that includes the bell.

If I have to do it without printing anything else, it's 4 characters:

7{a.

Answer 14

Mathematica 6

This will evoke the system beep. On my computer, it is currently a chirp.

Beep[]

Answer 15

Pascal: 30 characters

uses Crt;begin
Sound(999)
end.

This takes advantage of the lack of any rule regarding the sound's duration. So just turns on the speaker on 999 Hz and lets it so. (At least until another program calls Nosound or the computer is turned off.)

Answer 16

cat/type/PHP 1

This is actually polyglot. It runs in cat (or Microsoft Cat called type) and PHP.

$ xxd file
0000000: 07                                       .

Execution:

$ xxd -r > file
0000000: 07                                       .
^D
$ cat file # cat could be replaced with type (on Windows) or with php

Answer 17

Bash, 22

Back in the 90's, my brother taught me this one -- to be used in a computer lab where one has remote access and knows a person to be alone in said lab. Kids these days won't know what a computer lab is... but oh well.

cd /dev;cat sda1>audio

Answer 18

brainfuck, 5 bytes

+[.+]

prints all chars including bell

Answer 19

R 9

The bell character

cat("\a")

Answer 20

Ruby, 7

$><<?\a

Tested on Windows with Ruby 1.9.3.

Answer 21

DOS, 5

Indirect, requires user cooperation.

pause

Answer 22

Python 9 chars

---

produces beep sound when executed.

print'\a'

Answer 23

Applescript (4 Characters)

beep

This will play the default beep sound of OS X.

Answer 24

PowerShell, 24 17

Since nobody has posted this version yet:

[console]::beep()

UPDATE: Removed frequencies so it uses the default frequency and duration (MSDN says the default is 800 hertz and 200 milliseconds)

Answer 25

Mathematica 7

Using Mathematica's built in text to speech capability.

Speak@x

Will make it say "x"

Answer 26

top & aplay - 9

top has rhythm!

top|aplay

The periodic display sometimes does not feed the sound sink fast enough but aplay continues after grouching a bit... :-)

...this will run on many Linuxes...

Bonus:

While running this, type "s 1 ENTER" to get more beats per second. :-)

Party on!!! \o/

Answer 27

><> 3

As in all answers, prints the bell (0x07) to stdout.

7o;

Answer 28

Tcl, 1 char

-

replace - with the bell char.
It will print the bell char as part of the error message. Twice.

And if you think this is not a valid program, add this before the bell char:

proc \007 {} {};

It is a valid program, I just did not define the command, because I like the error message.

Answer 29

C: 19

main(){puts("\a");}

edit: header file is not needed for "puts"

Answer 30

Ruby 8

 puts"\a"

Tested on Windows with Ruby 1.9.3.
