How to use sounds in a C# application

Various programs use various sounds to give an alert about various tasks. Here in C# we can use various sounds with form's load event,for a button click, for a check box etc... Basically there are two methods to use sound in C#.

First one is :-By using beep tones and second is by using audio files(.wav,.mp3 etc...).

So this post is about beep tones.

In Windows operating system there are various sounds to inform user about some tasks like “low battery”, “updates available” etc.. In some cases windows use beep tones also. So let's get know about how to use beep tones in a C# application.

First create new project and name it as “beeptest”.

Now double click on your form1 and here you have code window and you are at form's load event.

Then type this code →

                        Console.Beep();

and press “F5” or go to debug and click on “Start Debugging”.

Now you can here a beep tone when form loads.

Now try to use beeps with a button.

Now get a button to form and change it's text as “Click to beep” .

Then double click on the button and type this code in button's click event.

                      Console.Beep();

Now if you run this and click on the button you can here a beep tone.

Now let's study about the code “Console.Beep();”.

This is the general form of beep tones. But you can change the frequency of beeps. Now look at the code below.

                       Console.Beep(Frequency,Time period);

Here frequency varies from 37Hz to 32767Hz. If you want to use base sounds you can use low frequencies like 37,40 ,50 39 etc..

Time period means the amount of time that you can here the beep. Here in C# to here a beep sound for a 1 second you must use time period as “1000”.

Now get a new button and code this in it's click event.

                         Console.Beep(400,1000);

After running and clicking on the button1 you can here a beep tone with 400Hz frequency for a period of one second.

Try some more examples by changing frequency and time period.

Now I think you have got it.

Here we are going to make a soft organ with the help of beep tones.

Now open a new project and name it as “softorgan”.

Now change your form's name as you like or keep it as it's default (form1).

Here we have to use 13 buttons.

Get a button to the form.

Now change it's text property as “&S”.

Now get a label to the form and keep it under the button and change it's text property to “C”.

Now get another button and change it's text property as “&E”.

Now get another label to the form and keep it under the button and change it's text property to “C#”.

Accordingly get another 11 buttons and change there text properties as , “&D”, “&R”,“&F”,“&G”,“&Y”,“&H”,“&U”,“&J”, “&I”, “&K” and “&L”. Then get 11 labels and change their text properties as “D”, “Eb”, “E”, “F”, “F#”, “G”, “Ab”, “A”, “Bb”, “B”and “C”.

Now look at the picture below and align your buttons and labels as keys in keyboard.

Now it's time to code.

Double click on key C (first button) and type this code →

                                 Console.Beep(261,200);

Now code these codes accordingly second button and so on.

Second button(C#)        Console.Beep(277,200);

Third button(D)             Console.Beep(293,200);

Fourth button(Eb)         Console.Beep(311,200);

Fifth button(E)              Console.Beep(329,200);

Sixth button(F)              Console.Beep(349,200);

Seventh button(F#)       Console.Beep(370,200);

Eighth button(G)           Console.Beep(392,200);

Ninth button(Ab)          Console.Beep(415,200);

Tenth button(A)            Console.Beep(440,200);

Eleventh button(Bb)     Console.Beep(466,200);

Twelfth button(B)         Console.Beep(494,200);

Thirteenth button(C)     Console.Beep(523,200);

You can change the amount of time period by increasing or decreasing the value “200”.

Now it' time to play our soft organ.

Press F5 or go to debug menu and click on “start debugging”.

Now you can play using your mouse or using appropriate key in your keyboard.

(ex: to play C press “s” in your keyboard)

Thank you!
