My other software was a failure; I should think of others rather than what I found back then good or useful, and I was an idiot. So I got digging and researching, and I think I’m the only one who made something like this. What it does is let you pick three options at the beginning of a terminal window.

[1] Enter Millisecond(s)-per-beat to get statistics

[2] Enter Beat(s)-per-second to get statistics

[3] Enter Beat(s)-per-minute to get statistics

If you pick [1], enter Millisecond(s)-per-beat to get statistics, and you enter the number 500. This is what it’ll show you.

Scroll up to see the calculated data

[R]edo or [Q]uit?

You get the idea. If you want 4 beats per second in the second option, just type in and enter 4 when you pick that option. If you want BPM statistics, type in the BPM value. Decimals are also allowed. And I put no limit on how high it can go, only what the computer can handle; it also handles negative numbers just for fun, I guess. It also goes up to 256 lines per beat just for the sake of completion; I think what you’d want is up to 64. Anyways, The calculations are seemingly instant, and I ran it on a netbook, and on Linux, the software uses 4.0 KB of RAM. I’m sure someone can find this useful; I sometimes like messing with it. A Linux executable is included with the source code. So if you want to run it on Windows or macOS, you’d have to compile it yourself.
