Implementation of an ADSR envelope.

Basic usage

use std::time::Duration;

use augmented_adsr_envelope::Envelope;

// Create an exponential envelope.
// The envelope configuration uses atomics, so it doesn't need
// to be an immutable reference.
let envelope = Envelope::exp();

// Set settings
envelope.set_sample_rate(1000.0);
envelope.set_attack(Duration::from_millis(200));

// Trigger the envelope
envelope.note_on();
for i in 0..10000 {
  // Tick the envelope by 1 sample
  envelope.tick();
  // Get the current volume
  let _volume = envelope.volume();
}
// Trigger the release stage
envelope.note_off();
