Sound-playing interface for Windows in Python (winsound)
The winsound module is specific to Python installation on Windows operating system. The module defines following functions −
Beep()
When this function is called a beep is heard from the PC’s speaker. The function needs two parameters. The frequency parameter specifies frequency of the sound, and must be in the range 37 through 32,767 hertz. The duration parameter specifies duration of sound in .
>>> import winsound >>> winsound.Beep(1000,500)
MessageBeep()
This function plays a sound as specified in the registry. The type argument specifies which sound to play. Possible values are −
-1, MB_ICONASTERISK, MB_ICONEXCLAMATION, MB_ICONHAND, MB_ICONQUESTION, and MB_OK (default).
The value -1 produces a "simple beep"
>>> winsound.MessageBeep()
PlaySound()
This function Calls the underlying PlaySound() function from the Platform API. The function needs two parameters. The sound parameter may be a filename, a system sound alias, or audio data as a bytes-like object. Its interpretation depends on the value of flags. The flags are as defined below:
| SND_FILENAME | The sound parameter is the name of a WAV file. |
| SND_LOOP | Play the sound repeatedly |
| SND_MEMORY | The sound parameter to PlaySound() is a memory image of a WAV file, as a bytes-like object. |
| SND_ASYNC | Return immediately, allowing sounds to play asynchronously. |
| SND_NODEFAULT | If the specified sound cannot be found, do not play the system default sound. |
| SND_NOSTOP | Do not interrupt sounds currently playing. |
Following statement plays the given WAV file.
>>> winsound.PlaySound('sample.wav', winsound.SND_FILENAME|winsound.SND_NOWAIT)SND_ALIAS
The Windows registry keys are associated with sound names.If the registry contains no such name, play the system default sound unless SND_NODEFAULT. All Win32 systems support the following:
| PlaySound() name | Corresponding Control Panel Sound name |
|---|---|
| 'SystemAsterisk' | Asterisk |
| 'SystemExclamation' | Exclamation |
| SystemExit' | Exit Windows |
| 'SystemHand' | Critical Stop |
| SystemQuestion' | Question |
For example following statement plays Windows Exit sound.
>>> winsound.PlaySound("SystemExit", winsound.SND_ALIAS)The winsound module also defines following sounds
| MB_ICONASTERISK | Play the SystemDefault sound. |
| MB_ICONEXCLAMATION | Play the SystemExclamation sound. |
| MB_ICONHAND | Play the SystemHand sound. |
| MB_ICONQUESTION | Play the SystemQuestion sound. |
| MB_OK | Play the SystemDefault sound |
