Expand description

Loudness metadata for a single track

Fields§

§track_id: String

Unique identifier (file path or hash)

§file_path: String

Original file path

§integrated_lufs: f64

Integrated loudness in LUFS

§true_peak_dbtp: f64

True peak in dBTP

§loudness_range: Option<f64>

Loudness range in LU (optional)

§track_gain_db: f64

Pre-computed track gain in dB (target - integrated)

§album_gain_db: Option<f64>

Album gain in dB (optional, for album mode)

§scan_version: i32

Scanner algorithm version

§scanned_at: i64

Unix timestamp of scan

§file_mtime: Option<i64>

Implementations§

Source §

impl TrackLoudness

Source

pub fn new( file_path: &str, integrated_lufs: f64, true_peak_dbtp: f64, loudness_range: Option<f64>, target_lufs: f64, ) -> Self

Create a new loudness record from measurement results

FIX for Defect 40: Record file mtime and size for change detection. If file metadata cannot be read (e.g., HTTP URL), these will be None.

Source

pub fn gain_for_target(&self, target_lufs: f64) -> f64

Get gain in dB for a specific target loudness

Source

pub fn gain_linear(&self, target_lufs: f64) -> f32

Convert dB gain to linear coefficient
