Lala Sing

Lala Sing is a singing practice app. Split a song into the backing track and the vocals, sing along over the original melody, and get your pitch and timing scored — the separation and the scoring run on your phone.

AI VOCAL SEPARATION
• Splits music files (MP3, M4A, FLAC, WAV) into the backing track and the vocals
• Keep songs unseparated and separate them whenever you like

SINGING PRACTICE
• Your pitch is drawn live over the reference melody taken from the original vocals
• Pitch accuracy is scored while you sing, with a score report at the end
• Key change (the tempo stays), loop a passage, countdown before the song starts
• Backing, vocal and microphone levels, reverb and echo, hear yourself through headphones
• Use the phone's microphone, wired earphones or a Bluetooth headset

LYRICS AND RECORDINGS
• Synced lyrics from the music file (LRC and more) follow the song
• Look up synced lyrics in the public LRCLIB database only when you ask, or type them in and time them yourself
• Record while you practise, listen back and compare with the original melody
• Save and export the backing track and the vocals as lossless FLAC

ORGANISE AND SHARE
• Your library: folders, search, tidy many songs at once
• Export and import song files, save to your own Google Drive or Dropbox (optional)

GOOD TO KNOW
• Free with a small banner ad; a one-time purchase removes the ads for good
• No account needed
• Songs, recordings and scores stay on your phone (except in a drive you connect yourself)
• 41 languages
• Separation speed depends on your phone; a newer phone is much faster.
• You bring the music files to separate and practise with; use copyrighted songs for personal practice only.
