I was generating an audio file on WSL and wanted to play it from a command. It was an exaggeration to run the sound server, so I made a simple program in Python on the Windows side and called it via a wrapper.

Library

In the next article, you'll find a lot of Python sound libraries.

Handling sound with Python

This time we will use playsound. Install with pip on Python on the Windows side.

`Library installation`


py.exe -m pip install playsound

Since py.exe is located in the path (C: \ WINDOWS) on the Windows side, you can call it from WSL by adding .exe.

Body

playsound is easy to use by simply importing and passing the filename.

Added a function to specify multiple files and display the name of the file being played. (-P option)

`winplay.py`


import sys, playsound
if len(sys.argv) < 2:
    print("usage: %s [-p] sound [...]" % sys.argv[0])
    print("    -p: show file name")
    exit(1)
argp = 2 if sys.argv[1] == "-p" else 1
args = sys.argv[argp:]
argl = len(args)
format = "[%%%dd/%%d] %%s" % len(str(argl))
for i, arg in enumerate(args):
    if argp > 1: print(format % (i + 1, argl, arg))
    playsound.playsound(arg)

WSL

Place wintts.py somewhere visible to Windows. Write a simple wrapper like the following and place it wherever the path is in WSL and add the execute attribute.

`winplay`


#!/bin/sh
py.exe 'C:\Script storage\winplay.py' "$@"

You can now use it as if it were a WSL command.

`Example of use`


winplay test.wav
winplay -p *.wav

MP3

MP3s can be played for the time being, but in my environment, playback was interrupted and other phenomena occurred.

This time, the purpose is a WAVE file, so we have not investigated it.

About the name

I prefixed it with win- to indicate that it works on the Windows side.

Actually, at first, I tried to name the library as it is playsound, but I canceled it because I was addicted to import.

File name is bad in Python and I was addicted to import
