Crate lufsgen 

LUFS Generator Library for Android

A memory-efficient streaming LUFS (Loudness Units Full Scale) calculator that processes audio chunk-by-chunk without loading entire files into memory.

Features

• Streaming audio decoders for MP3, OGG, WAV, FLAC, AAC, M4A, and MP4 formats
• Automatic format detection from stream content (magic bytes)
• Memory-efficient chunk-based processing
• EBU R128 compliant loudness measurement

Example

use lufsgen::LufsCalculator;
use std::path::Path;

let calc = LufsCalculator::default();

// From file path - format is auto-detected
let lufs = calc.calculate_from_file(Path::new("song.mp3"))?;

// Supports many formats: mp3, ogg, wav, flac, aac, m4a, mp4
let lufs_flac = calc.calculate_from_file(Path::new("song.flac"))?;
