Making sound with different frequencies

Question

Is there a function in X11 or built into Linux that can produce a Beep sound with different frequencies?

Some function like the Beep(dwFreq, dwDuration) function in Windows which has arguments that allows for the specification of frequency in hertz and a duration in milliseconds.

You may want to start with [xbell(3) - Linux man page](http://linux.die.net/man/3/xbell) then look at [xdevicebell(3) - Linux man page](http://linux.die.net/man/3/xdevicebell) then look at [xchangefeedbackcontrol(3) - Linux man page](http://linux.die.net/man/3/xchangefeedbackcontrol) however it may be a bit complicated.

This is actually a good question and I would be interested in an answer as well. — Richard Chambers, Sep 07 '15 at 19:46

Try with speaker-test(1). It can be usually found on alsa-utils package.

example (generates a sine wave, 440 Hz):

speaker-test -f 440 -t sine

How can I adjust time? – Minimus Heximus Sep 08 '15 at 20:29
Check `man speaker-test`. Maybe you can find one option that helps. – Paco Esteban Sep 08 '15 at 21:22
I tested options but it always produces a 10 sec Beep. – Minimus Heximus Sep 08 '15 at 21:24

Well, if you can't find a solution you can always go with `speaker-test -f 440 -t sine & ; sleep 2 ; killall speaker-test` for 2 seconds. Depending on your implementation of sleep you can use any floating point number. But this is nasty. – Paco Esteban Sep 10 '15 at 09:30
