time_calc 
A library for music/DSP time conversions!
time_calc provides functions and methods for converting between ticks, ms, samples, bars, beats and measures.
It looks like this:
const SAMPLE_HZ: SampleHz = 44_100.0;
let bpm: Bpm = 120.0;
let time_sig = TimeSig { top: 4, bottom: 4 };
println!("Convert 4 bars to samples where the tempo is 120bpm, the time signature is 4/4
and the sample rate is 44,100 samples per second: {}",
Bars(4).samples(bpm, time_sig, SAMPLE_HZ))Usage
Add time_calc to your cargo dependencies like this:
[dependencies]
time_calc = "*"
