Python winsound basic introduction



What is winsound?

The winsound is a python module which  provides access to the basic sound-playing machinery provided by Windows platforms. It includes functions and several constants.
the purpose of introducing to you the winsound module  the task of generating or playing sound or a sound file.
The winsound module is defined only for execution on a Windows Platform, hence the name WINsound
Installation
the winsound module is a builtin, there is no need for you to install it prior to executing it.
The basic action would be to import it by 
import winsound
Functions
winsound.Beep( )
This function is used to generate a ‘Beep’ sound. However, the user is required to input the frequency 
 value and the duration of the sound (these are parameters that shall be passed while calling the function).
Note: The frequency must be in the range 37 through 32,767 hertz.

#code
import winsound 
# frequency is set 
freq = 400
  
# duration is set to 100 milliseconds             
dur = 100
               
winsound.Beep(freq, dur)
#output
system will produce a ‘Beep’ sound with the given frequency 
for the given duration of time.
winsound.PlaySound()
It has two parameters first sound and otherone is flag. The sound parameter may be a filename, a system sound alias, audio data as a bytes-like object, or none .Its interpretation depends on the value of flags, which can be a bitwise ORed combination of the constants described below. If the sound parameter is None, any currently playing waveform sound is stopped. If the system indicates an error, RuntimeError is raised.

Flags and their description
SND_FILENAMEThe sound parameter is the name of a WAV file.
SND_LOOPPlay the sound repeatedly
SND_MEMORYThe sound parameter to PlaySound() is a memory image of a WAV file, as a bytes-like object.
SND_ASYNCReturn immediately, allowing sounds to play asynchronously.
SND_NODEFAULTIf the specified sound cannot be found, do not play the system default sound.

    SND_NOSTOP    Do not interrupt sounds currently playing.

#code 
import winsound

print("Playing the file 'Police siren.wav'")

# winsound.PlaySound('filename', flag)
winsound.PlaySound('mixkit-police-siren-us-1643.wav', winsound.SND_FILENAME)


#output
The respective audio file named 'mixkit-police-siren-us-1643.wav' is executed.	

Here, mixkit-police-siren-us-1643 is .wav formate file name 
and SND_FILENAME  is flag name
