bliss audio library
bliss is a library for making “smart” audio playlists.
The core of the library is the Song
object, which relates to a
specific analyzed song and contains its path, title, analysis, and
other metadata fields (album, genre…).
Analyzing a song is as simple as running Song::new("/path/to/song")
.
The analysis field of each song is an array of f32, which makes the comparison between songs easy, by just using euclidean distance (see distance for instance).
Once several songs have been analyzed, making a playlist from one Song is as easy as computing distances between that song and the rest, and ordering the songs by distance, ascending.
It is also convenient to make plug-ins for existing audio players. It should be as easy as implementing the necessary traits for Library. A reference implementation for the MPD player is available here
Examples
Analyze & compute the distance between two songs
use bliss_audio::{BlissResult, Song}; fn main() -> BlissResult<()> { let song1 = Song::new("/path/to/song1")?; let song2 = Song::new("/path/to/song2")?; println!("Distance between song1 and song2 is {}", song1.distance(&song2)); Ok(()) }
Make a playlist from a song
use bliss_audio::{BlissResult, Song}; use noisy_float::prelude::n32; fn main() -> BlissResult<()> { let paths = vec!["/path/to/song1", "/path/to/song2", "/path/to/song3"]; let mut songs: Vec<Song> = paths .iter() .map(|path| Song::new(path)) .collect::<BlissResult<Vec<Song>>>()?; // Assuming there is a first song let first_song = songs.first().unwrap().to_owned(); songs.sort_by_cached_key(|song| n32(first_song.distance(&song))); println!( "Playlist is: {:?}", songs .iter() .map(|song| song.path.to_string_lossy().to_string()) .collect::<Vec<String>>() ); Ok(()) }
