Module silence 

Silence detection and trimming utilities

Detects silent regions in audio and trims leading/trailing silence.

Algorithm:

1. Frame audio into chunks
2. Compute RMS energy per frame
3. Mark frames below threshold as silent
4. Merge consecutive silent frames (< 500ms)
5. Trim leading/trailing silence

Example

use stratum_dsp::preprocessing::silence::{detect_and_trim, SilenceDetector};

let samples = vec![0.0f32; 44100 * 5]; // 5 seconds
let detector = SilenceDetector::default();
let (trimmed, silence_map) = detect_and_trim(&samples, 44100, detector)?;
