Beep for WSL Ubuntu and OpenSUSE in Windows 10, and Cygwin. The
built-in beep in
Ubuntu/OpenSUSE doesn't work in WSL (Windows Subsystem for Linux), but I've modified it to use
Windows Beep()
e.g. powershell.exe "[console]::beep(261.6,700)". In a WSL Linux the frequency must be between 37.0 and 32767.0 Hz,
but it pauses the right time if the frequency is less than 37.0. The original beep supported floating point frequences,
but in Windows they are probably truncated to integers.
Build and install in Ubuntu, Cygwin and OpenSUSE using:
make
sudo make install
In Cygwin you need to leave out sudo. In OpenSUSE you have to also do:
unalias beep
export PATH=$PATH:/mnt/c/Windows/System32/WindowsPowerShell/v1.0
Then you can try beep -f 261.6 -l 700. To read the manual using man beep doesn't work well in OpenSUSE for unknown reasons.
This makes it possible to play the files in https://github.com/ShaneMcC/beeps or https://github.com/Josef-Friedrich/beep-melodies or the command-lines in https://www.reddit.com/r/linux/comments/18h8v5/does_anyone_have_or_know_a_source_for_beep_scripts/.
You can break out of the playing scripts by pressing Ctrl C for a long time.
Now I use system(), but one might use a more direct call with less overhead, but I don't know how. Another alternative would
be to write a TCP/IP sound server.
It is possible to install this beep without compiling using a repository: https://github.com/cerebrate/wsl-translinux.
