audiotags

This crate makes it easier to parse tags/metadata in audio files of different file types.

This crate aims to provide a unified trait for parsers and writers of different audio file formats. This means that you can parse tags in mp3 and m4a files with a single function: audiotags::from_path() and get fields by directly calling .album(), .artist() on its result. Without this crate, you would otherwise need to learn different APIs in id3, mp4ameta crates in order to parse metadata in different file foramts.

Example

use audiotags;

fn main() {
    const MP3: &'static str = "a.mp3";
    let mut tags = audiotags::from_path(MP3).unwrap();
    // without this crate you would call id3::Tag::from_path()
    println!("Title: {:?}", tags.title());
    println!("Artist: {:?}", tags.artist());
    tags.set_album_artist("CINDERELLA PROJECT");
    let album = tags.album().unwrap();
    println!("Album title and artist: {:?}", (album.title, album.artist));
    println!("Track: {:?}", tags.track());
    tags.write_to_path(MP3).unwrap();
// Title: Some("お願い！シンデレラ")
// Artist: Some("高垣楓、城ヶ崎美嘉、小日向美穂、十時愛梨、川島瑞樹、日野茜、輿水幸子、佐久間まゆ、白坂小梅")
// Album title and artist: ("THE IDOLM@STER CINDERELLA GIRLS ANIMATION PROJECT 01 Star!!", Some("CINDERELLA PROJECT"))
// Track: (Some(2), Some(4))

    const M4A: &'static str = "b.m4a";
    let mut tags = audiotags::from_path(M4A).unwrap();
    // without this crate you would call mp4ameta::Tag::from_path()
    println!("Title: {:?}", tags.title());
    println!("Artist: {:?}", tags.artist());
    let album = tags.album().unwrap();
    println!("Album title and artist: {:?}", (album.title, album.artist));
    tags.set_total_tracks(4);
    println!("Track: {:?}", tags.track());
    tags.write_to_path(M4A).unwrap();
// Title: Some("ふわふわ時間")
// Artist: Some("桜高軽音部 [平沢唯・秋山澪・田井中律・琴吹紬(CV:豊崎愛生、日笠陽子、佐藤聡美、寿美菜子)]")
// Album title and artist: ("ふわふわ時間", Some("桜高軽音部 [平沢唯・秋山澪・田井中律・琴吹紬(CV:豊崎愛生、日笠陽子、佐藤聡美、寿美菜子)]"))
// Track: (Some(1), Some(4))
