(formerly Perl 6)
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.
<lang perl6>sub MAIN ($beats-per-minute = 72, $beats-per-bar = 4) {
my $duration = 60 / $beats-per-minute;
my $base-time = now + $duration;
my $i;
for $base-time, $base-time + $duration ... * -> $next-time {
if $i++ %% $beats-per-bar {
print "\nTICK";
}
else {
print " tick";
}
sleep $next-time - now;
}
