Fun with /dev/speaker

Haha, fun. I bookmarked your original post and finally tried it on my FreeBSD NAS (no speaker in the FW). Is the alpha the note and the numeric the duration?

@provels my understanding is that speaker understands some form of Music Macro LanguageMML

Yes, it’s note followed by duration as a fraction of a note.

@provels BTW a lot of boards don’t have piezo speakers on the board, but do have a pair of header pins and a piezo speaker runs a couple of bucks on Amazon etc.

Reminds of my old days with DOS 3.1 on my IBM clone. Thanks for the wiki link. Now to compose the "Office" theme...

@provels ooh, cool. Maybe the theme from “The Equalizer” too? ;-)

Trying to find an online convertor for MIDI to MML, but the output does not resemble your original post. Obvs, too many < > < < ...

@provels Do see spkr (4) for the exact syntax supported.

Yeah, you need quotes around it.
spkrtest(8) is also included for further fun.
