Lacuna

What is Lacuna?

Lacuna is a web-based AI audio studio that generates, edits, and processes music, vocals, and MIDI files. It serves musicians and creators who need to produce songs from text, hummed melodies, or images, as well as those requiring stem separation, mastering, and notation conversion. An account is required to generate and save tracks, though signing up is free and does not require a credit card.

What are the features of Lacuna?

• Music generation canvas

  Generates songs from text descriptions, hummed melodies, photos, or MIDI files, producing two draft directions per request on a visual editing canvas.
• Stem separation

  Splits uploaded or generated tracks into two, four, or six stems including vocals, drums, bass, guitar, and piano for individual download or rebalancing.
• MIDI and notation conversion

  Transcribes sheet music PDFs and images to editable MIDI, converts between MusicXML, ABC notation, and MIDI, and renders MIDI back to sheet music or audio.
• Voice cloning and covers

  Trains a private singing voice model from 2–30 minutes of recordings and applies it to existing tracks or new generations while preserving melody and backing.
• Section-level lyric editing

  Regenerates a selected portion of a song's waveform with new lyrics without altering the rest of the track.
• Audio mastering

  Matches a mix to reference presets like Balanced & Clear or Loud & Punchy, outputting WAV (16- or 24-bit) or 320 kbps MP3 with LUFS and true peak readings.

What are the use cases of Lacuna?

• Karaoke and backing track creation

  Isolating or removing lead vocals, backing vocals, or specific instruments from an uploaded song to produce practice or performance tracks.
• Sheet music digitization

  Converting printed multi-page PDF scores or phone photos into editable MIDI or MusicXML files for further arrangement.
• Personalized song gifting

  Generating custom birthday, lullaby, or holiday songs incorporating specific names and memories provided by the user.
