[[File:Metronome.jpg|420px||right]]
The task is to implement a [https://en.wikipedia.org/wiki/Metronomemetronome metronome].
The metronome should be capable of producing high and low audio beats, accompanied by a visual beat indicator, and the beat pattern and tempo should be configurable.
For the purpose of this task, it is acceptable to play sound files for production of the beat notes, and an external player may be used.
However, the playing of the sounds should not interfere with the timing of the metronome.
The visual indicator can simply be a blinking red or green area of the screen (depending on whether a high or low beat is being produced), and the metronome can be implemented using a terminal display, or optionally, a graphical display, depending on the language capabilities.
If the language has no facility to output sound, then it is permissible for this to implemented using just the visual indicator.

Using <code>usleep</code> with self correcting delays. Audio is the bell character, which will definitely drive one insane (but I'm ok: my computer doesn't have the bell device). Invoke with <code>./a.out [beats_per_minute]</code>, default to 60.

An Apple Mac application that, when compiled with FB, produces a packaged, stand-alone 64-bit application that will run on either Intel or the newer M-series Macs. It's GUI includes a slider control to adjust speed, as well as blinking indicator and a sound, to indicate tempo. The code has been tested on Catalina (10.15.x) to Monterey (12.4.x) with Ventura still in beta at the time of this post. The free FB compiler is available on the

As with the [[#Raku|Raku example]], just simple text output.
It would be reasonably simple (but covered better in other tasks)
to change bpm and bpb into command line arguments,
make it a function/object,
and/or substitute sound production instead of text output.
<code>time.Ticker</code>'s documentation says that it
"adjusts the intervals or drops ticks to make up for slow receivers".
So, as long as the output or sound production finishes before the next tick,
the timing will be reliable and will not drift which is the gist of this task.

The explicit version (nbars,t) MET (barlengths;bpm) prints a bell character every beat, accompanied by a sequence of slashes, spaces, and backspaces to create a little animation. It includes a beat hand and a measure (or bar) hand.<br>
MET can take several barlengths and bpm values, in which case it will cycle through them individually at each measure, creating (perhaps) interesting patterns. It will stop when nbars measures have been cycled through, or at the end of the current measure if the time limit is exceeded. The clock is self correcting.<br>
MET returns the total number of measures, beats, and elapsed time.<br>
If you leave out the left arguments, it will set them to infinity, so you can go insane without worrying about the metronome ever stopping.

This code only uses textual output, but any noise-generating commands may be substituted; as long as they are executed synchronously, and do not run longer than the specified duration, the timing loop will compensate, since the sequence operator is determining a list of absolute times for each <tt>sleep</tt> to target.
